At a special event before CES 2018, AMD released new mobile processors and announced desktop chips with integrated graphics. And Radeon Technologies Group, a structural division of AMD, announced Vega mobile discrete graphics chips. The company also revealed plans to switch to new technical processes and promising architectures: Radeon Navi graphics and Zen+, Zen 2 and Zen 3 processors.

New processors, chipset and cooling

The first Ryzen desktops with Vega graphics

Two Ryzen desktop models with integrated Vega graphics will go on sale on February 12, 2018. The 2200G is an entry-level Ryzen 3 processor, while the 2400G is a mid-range Ryzen 5 processor. Both models dynamically boost clock speeds by 200 and 300 MHz from base frequencies of 3.5 GHz and 3.6 GHz, respectively. In fact, they replace the ultra-budget models Ryzen 3 1200 and 1400.

The 2200G has only 8 graphics units, while the 2400G has 3 more. The frequency of the 2200G graphics cores reaches 1,100 MHz, and the 2400G is 150 MHz more. Each graphics unit contains 64 shaders.

The cores of both processors have the same code name as mobile processors with integrated graphics - Raven Ridge (literally Raven Mountain, a rock formation in Colorado). But nevertheless, they are connected to the same LGA AMD AM4 socket as all other Ryzen 3, 5 and 7 processors.

Reference: Sometimes AMD calls processors with integrated graphics not CPU (Central Processing Unit, English Central processing unit), and APU (Accelerated Processor Unit, English. Accelerated processing unit, in other words, a processor with a video accelerator).
Tabletop AMD processors with built-in graphics are marked with the letter G at the end, after the first letter of the word graphics ( English graphic arts). Mobile processors from both AMD and Intel are marked with the letter U at the end, after the first letter of the words ultrathin ( English ultra-thin) or ultra-low power ( English above low power consumption) respectively.
At the same time, you should not think that if the model numbers of the new Ryzen begin with the number 2, then their core architecture belongs to the second generation of the Zen microarchitecture. This is not true - these processors are still in the first generation.

New Ryzen mobiles with Vega graphics

Last year, AMD already brought the first mobile Ryzen to the market under the code name Raven Ridge. The entire Ryzen mobile family is designed for gaming laptops, ultrabooks and tablet-laptop hybrids. But there were only two such models, each in the middle and high-end segments: Ryzen 5 2500U and Ryzen 7 2700U. The junior segment was empty, but the company corrected this right at CES 2018 - two models were added to the mobile family: Ryzen 3 2200U and Ryzen 3 2300U.

AMD Vice President Jim Anderson demonstrates the Ryzen mobile family

The 2200U is the first dual-core Ryzen CPU, while the 2300U is quad-core as standard, but both run four threads. At the same time, the base frequency of the 2200U cores is 2.5 GHz, and the lower 2300U is 2 GHz. But with increasing loads, the frequency of both models will rise to the same level - 3.4 GHz. However, laptop manufacturers can lower the power ceiling, because they also need to calculate energy costs and think through the cooling system. There is also a difference in cache size between the chips: the 2200U has only two cores, and therefore has half the cache of levels 1 and 2.

The 2200U has only 3 graphics units, but the 2300U has twice as many, as well as processor cores. But the difference in graphics frequencies is not so significant: 1,000 MHz versus 1,100 MHz.

The first mobile Ryzen PRO

AMD has planned release for the second quarter of 2018 mobile versions Ryzen PRO, processors corporate level. Characteristics mobile PRO identical to the consumer versions, with the exception of the Ryzen 3 2200U, which did not receive a PRO implementation at all. The differences between desktop and mobile Ryzen PRO are in additional hardware technologies.

Ryzen PRO processors are complete copies of regular Ryzen, but with additional features

For example, TSME, hardware encryption is used to ensure security random access memory“on the fly” (Intel only has software-intensive SME encryption). And for centralized management of a fleet of machines, the open standard DASH (Desktop and mobile Architecture for System Hardware) is available. system devices) - support for its protocols is built into the processor.

Laptops, ultrabooks and hybrid tablet-laptops with Ryzen PRO should primarily be of interest to companies and government agencies that plan to purchase them for employees.

New AMD 400 series chipsets

The second generation of Ryzen relies on the second generation of system logic: the 300th series of chipsets is replaced by the 400th. The flagship of the series, as expected, was the AMD X470, and later simpler and cheaper sets of circuits, such as the B450, would be released. The new logic has improved everything related to RAM: it has reduced access latency, raised the upper frequency limit, and added headroom for overclocking. Also in the 400 series, USB bandwidth has increased and the processor's power consumption has improved, and at the same time its heat dissipation.

But the processor socket has not changed. The AMD AM4 desktop socket (and its mobile non-removable version AMD FP5) is a special advantage of the company. The second generation has the same connector as the first. It will not change in the third and fifth generations. AMD promised, in principle, not to change AM4 until 2020. And for the 300 series motherboards (X370, B350, A320, X300 and A300) to work with the new Ryzen, you just need to update the BIOS. Moreover, in addition to direct compatibility, there is also reverse compatibility: old processors will work on new boards.

Gigabyte at CES 2018 even showed a prototype of the first motherboard based on the new chipset - the X470 Aorus Gaming 7 WiFi. This and other boards based on X470 and lower chipsets will appear in April 2018, simultaneously with the second generation of Ryzen on the Zen+ architecture.

New cooling system

AMD also introduced the new AMD Wraith Prism cooler. While its predecessor, the Wraith Max, was illuminated in a single color red, the Wraith Prism features motherboard-controlled RGB lighting around the perimeter of the fan. The cooler blades are made of transparent plastic and are also illuminated in millions of colors. Fans of RGB backlighting will appreciate it, and haters can simply turn it off, although in this case the point of buying this model will be negated.

Wraith Prism - a complete copy of Wraith Max, but with backlighting in millions of colors

The remaining characteristics are identical to the Wraith Max: direct contact heat pipes, programmable airflow profiles in overclocking mode and virtually silent operation at 39 dB under standard conditions.

There is no information yet on how much the Wraith Prism will cost, whether it will come bundled with processors, or when it will be available for purchase.

New Ryzen laptops

In addition to mobile processors, AMD is also promoting new laptops based on them. In 2017, the HP Envy x360, Lenovo Ideapad 720S and Acer Swift 3 models were released on mobile Ryzen. In the first quarter of 2018, the Acer Nitro 5, Dell Inspiron 5000 and HP series will be added to them. They all run on last year's mobile Ryzen 7 2700U and Ryzen 5 2500U.

The Acer Nitro family is all about gaming machines. The Nitro 5 line is equipped with 15.6-inch IPS displays with a resolution of 1920 × 1080. And some models will be equipped with a discrete Radeon RX 560 graphics chip with 16 graphics units inside.

The Dell Inspiron 5000 line of laptops offers models with display diagonals of 15.6 and 17 inches, equipped with either hard drives or solid state drives. Some models in the line will also receive discrete video card Radeon 530 with 6 graphics units. This is a rather strange configuration, because even the integrated graphics of the Ryzen 5 2500U have more graphics units - 8 pieces. But the advantage of a discrete card may be higher clock speeds and separate graphics memory chips (instead of the RAM section).

Price reduction for all Ryzen processors

Plans until 2020: Navi graphics, Zen 3 processors

2017 was a completely turning point for AMD. After years of troubles, AMD completed development of the Zen core microarchitecture and released the first generation of CPUs: the Ryzen, Ryzen PRO and Ryzen Threadripper family of PC processors, the Ryzen and Ryzen PRO mobile family, and the EPYC server family. In the same year, the Radeon group developed the Vega graphics architecture: Vega 64 and Vega 56 video cards were released on its basis, and by the end of the year, Vega cores were integrated into Ryzen mobile processors.

Dr. Lisa Su, CEO of AMD, assures that the company will release 7 nanometer processors before 2020

The new products not only attracted the interest of fans, but also captured the attention of ordinary consumers and enthusiasts. Intel and NVIDIA had to quickly counter: Intel released six-core Coffee Lake processors, the unplanned second “so” of the Skylake architecture, and NVIDIA expanded the 10th series of video cards based on the Pascal architecture to 12 models.

Rumors about AMD's future plans accumulated throughout 2017. Until now, Lisa Su, CEO of AMD, has only noted that the company plans to exceed the 7-8% annual rate of productivity growth in the electronics industry. Finally, at CES 2018, the company showed a “road map” not just until the end of 2018, but right up to 2020. The basis of these plans is improving chip architectures through the miniaturization of transistors: a progressive transition from the current 14 nanometers to 12 and 7 nanometers.

12 nanometers: second generation Ryzen on Zen+

The Zen+ microarchitecture, the second generation of the Ryzen brand, is based on the 12-nanometer process technology. In fact, the new architecture is a modified Zen. The GlobalFoundries manufacturing standard is being converted from 14nm 14LPP (Low Power Plus) to 12nm 12LP (Low Power). The new 12LP process technology should provide chips with a 10% performance increase.

Reference: The GlobalFoundries network of factories are former AMD manufacturing facilities that were spun off into a separate company in 2009 and merged with other contract manufacturers. In terms of contract manufacturing market share, GlobalFoundries shares second place with UMC, significantly behind TSMC. Chip developers - AMD, Qualcomm and others - order production both from GlobalFoundries and other factories.

In addition to the new technical process, the Zen+ architecture and chips based on it will receive improved AMD Precision Boost 2 and AMD XFR 2 (Extended Frequency Range 2) technologies. In mobile Ryzen processors you can already find Precision Boost 2 and a special modification of XFR - Mobile Extended Frequency Range (mXFR).

The second generation will see the release of the Ryzen, Ryzen PRO and Ryzen Threadripper family of PC processors, but so far there is no information about updating the generations of the Ryzen and Ryzen PRO mobile family, and the server EPYC. But it is known that some models of Ryzen processors will have two modifications from the very beginning: with graphics integrated into the chip and without it. Entry- and mid-level models Ryzen 3 and Ryzen 5 will be released in both versions. And the high level Ryzen 7 will not receive any graphical modification. Most likely, the code name Pinnacle Ridge (lit. sharp mountain ridge, one of the peaks of the Wind River Range in Wyoming) is assigned to the core architecture for these particular processors.

The second generation of Ryzen 3, 5 and 7 will begin selling in April 2018 along with the 400 series chipsets. And the second generation of Ryzen PRO and Ryzen Threadripper will be late until the second half of 2018.

7 nanometers: third generation Ryzen on Zen 2, discrete Vega graphics, Navi graphics core

In 2018, the Radeon group will release discrete graphics Vega for laptops, ultrabooks and laptop tablets. AMD does not share any special details: it is known that discrete chips will work with compact multi-layer memory like HBM2 (integrated graphics use RAM). Separately, Radeon emphasizes that the height of the memory chips will be only 1.7 mm.

Radeon exec shows off integrated and discrete Vega graphics

And in the same 2018 year Radeon will transfer graphics chips based on Vega architecture from the 14 nm LPP process technology directly to 7 nm LP, completely jumping over 12 nm. But first, new graphics units will be supplied only for the Radeon Instinct line. This is a separate family of Radeon server chips for heterogeneous computing: machine learning and artificial intelligence- the demand for them is ensured by the development of unmanned vehicles.

And already at the end of 2018 or the beginning of 2019, ordinary consumers will wait for Radeon and AMD products on the 7-nanometer process technology: processors based on Zen 2 architecture and graphics based on Navi architecture. Moreover, the design work for Zen 2 has already been completed.

AMD partners are already familiarizing themselves with Zen 2 chips and will create motherboards and other components for the third generation Ryzen. AMD is gaining such momentum due to the fact that the company has two teams “jumping” over each other to develop promising microarchitectures. They started with parallel work on Zen and Zen+. When Zen was completed, the first team moved to Zen 2, and when Zen+ was completed, the second team moved to Zen 3.

7 nanometers “plus”: fourth generation Ryzen on Zen 3

While one AMD department is solving the problems of mass production of Zen 2, another department is already designing Zen 3 at a technological standard designated as “7 nm+”. The company does not disclose details, but indirect data suggests that the process will be improved by complementing the current deep ultraviolet lithography (DUV, Deep Ultraviolet) with a new hard ultraviolet lithography (EUV, Extreme Ultraviolet) with a wavelength of 13.5 nm.

GlobalFoundries has already installed new equipment for the transition to 5 nm

Back in the summer of 2017, one of the GlobalFoundries factories purchased more than 10 lithographic systems from the TWINSCAN NXE series from the Netherlands ASML. With partial use of this equipment within the same 7 nm process technology, it will be possible to further reduce power consumption and increase chip performance. There are no exact metrics yet - it will take some more time to debug the new lines and bring them to acceptable capacity for mass production.

AMD expects to begin organizing sales of chips at the 7 nm+ standard from processors based on the Zen 3 microarchitecture by the end of 2020.

5 nanometers: fifth and subsequent generations of Ryzen on Zen 4?

AMD has not yet made an official announcement, but we can safely speculate that the next frontier for the company will be the 5 nm process technology. Experimental chips based on this standard have already been produced by a research alliance of IBM, Samsung and GlobalFoundries. Crystals using a 5 nm process technology will no longer require partial, but full use of hard ultraviolet lithography with an accuracy above 3 nm. This is exactly the resolution that the TWINSCAN NXE:3300B lithography system from ASML purchased by GlobalFoundries provides.

A layer one molecule thick of molybdenum disulfide (0.65 nanometers) exhibits a leakage current of only 25 femtoamps/micrometer at 0.5 volts.

But the difficulty also lies in the fact that at the 5 nm process it will probably be necessary to change the shape of the transistors. The long-proven FinFETs (fin-shaped transistors, from English fin) may give way to promising GAA FETs (shape of transistors with surrounding gates, from English gate-all-around). It will take several more years to set up and deploy mass production of such chips. The consumer electronics sector is unlikely to receive them before 2021.

Further reduction of technological standards is also possible. For example, back in 2003, Korean researchers created a 3-nanometer FinFET. In 2008, a nanometer transistor was created at the University of Manchester based on graphene (carbon nanotubes). And in 2016, Berkeley Lab research engineers conquered the sub-nanometer scale: such transistors can use both graphene and molybdenum disulfide (MoS2). True, at the beginning of 2018, there had not yet been a way to produce an entire chip or substrate from new materials.

Sergey Pakhomov

Sales of laptops have long surpassed sales of desktop PCs, and today most home users rely on laptops. IN retail network A huge number of different laptop models are offered on both Intel and AMD platforms. On the one hand, such abundance pleases the eye, but on the other, the problem of choice arises. As you know, the performance of a computer is largely determined by the processor installed in it, but understanding modern families and symbols processors are not so easy. And if with the designations of mobile processors Intel everything is more or less clear, but AMD is in complete confusion with this. Actually, it was precisely this circumstance that prompted us to compile a kind of guide to mobile processors from AMD.

The range of AMD processors for laptops is more than diverse (see table). However, if we talk about modern processors, which makes sense to focus on, then we can limit ourselves to considering only 45-nm processors of the Phenom II, Athlon II, Turion II, V-series, Sempron families with the following core code names: Champlain, Geneva and Caspian.

Processors codenamed Champlain were announced by the company quite recently - in May 2010, while 45 nm processors codenamed Caspian were announced in September 2009.

The AMD family of mobile processors includes both quad-core and triple-, dual- and single-core models.

Each processor core has a 128 KB Level 1 (L1) cache, which is divided into a dual-channel 64 KB data cache and a dual-channel 64 KB instruction cache. In addition, each processor core has a dedicated L2 cache of 512 KB or 1 MB.

But AMD mobile processors do not have third-level cache memory (L3) (unlike their desktop counterparts).

All AMD mobile processors feature AMD 64 technology (64-bit computing support). In addition, all AMD processors are equipped with MMX, SSE, SSE2, SSE3 and Extended 3DNow! instruction sets, Cool'n'Quiet power saving technologies, NX Bit virus protection and AMD Virtualization technology.

So, let's look at the families of modern AMD mobile processors in more detail. And we will begin, naturally, by considering the AMD Phenom II family of quad-core processors.

AMD's mobile quad-core processor family is the 900 series of Phenom II processors.

All Phenom II 900 series processors have a 2 MB L2 cache (512 KB per processor core) and an integrated DDR3 memory controller. Additionally, all of these processors use 128-bit FPUs. The differences between the quad-core Phenom II 900 series processors include clock speed, power consumption, and supported memory. For its processors, AMD indicates another rather strange and, in our opinion, completely illogical characteristic - Maximum processor-to-system bandwidth (MAX CPU BW). We are talking about the total bandwidth of all buses between the processor and the system, or more precisely, the total bandwidth of the HyperTransport (HT) bus and the memory bus. If, for example, the processor works with DDR3-1333 memory, then the memory bus bandwidth is 21.2 GB/s (in dual-channel mode). Further, if the HyperTransport (HT) bus throughput is 3600 GT/s, which corresponds to a throughput of 14.4 GB/s, then the total throughput of the HyperTransport bus and the memory bus will be 35.7 GB/s. Of course, it would be more logical to indicate in the processor specification the maximum memory frequency that the processor supports, but... it is what it is. Fortunately, knowledge of the HyperTransport bus bandwidth and such a parameter as MAX CPU BW allows you to unambiguously determine the maximum memory frequency supported by the processor.

So, let's return to the family of quad-core Phenom II 900 series processors. This family is headed by the Phenom II X920 Black Edition(BE) with unlocked multiplier. This processor has the highest clock speed (2.3 GHz) in the AMD family of quad-core mobile processors and is the hottest - its power consumption is 45 W. The HyperTransport bus bandwidth is 3600 GT/s, and the MAX CPU BW parameter value is 35.7 GB/s. As you can easily calculate, this means that the built-in DDR3 memory controller supports memory with a maximum frequency of 1333 MHz (in dual-channel operating mode).

Two more models of AMD quad-core mobile processors are the Phenom II N930 and Phenom II P920. The Phenom II N930 has a clock speed of 2 GHz and a power consumption of 35 W, while the Phenom II P920 has a clock speed of 1.6 GHz and a power consumption of 25 W. For both processor models, the HyperTransport bus bandwidth is 3600 GT/s, but the Phenom II N930 processor supports DDR3-1333 memory, and the Phenom II P920 processor only supports DDR3-1066 memory.

AMD's tri-core mobile processor family is the 800 series of Phenom II processors. Today there are only two three-core models of mobile processors: Phenom II N830 and Phenom II P820, both equipped with a 1536 KB L2 cache (512 KB for each processor core) and an integrated DDR3 memory controller. The difference between these models is the clock speed, power consumption and the maximum frequency of supported DDR3 memory. Thus, the Phenom II N830 processor operates at a clock frequency of 2.1 GHz with a power consumption of 35 W, and the maximum frequency of DDR3 memory supported by the processor is 1333 MHz. The Phenom II P820 processor operates at a clock speed of 1.8 GHz with a power consumption of 25 W and supports DDR3-1066 memory.

In passing, we note that if the letter “P” is present in the marking of AMD processors, this means that the processor’s power consumption is 25 W. The presence of the letter “N” indicates a processor power consumption of 35 W, and the letter “X” indicates 45 W.

The Phenom II family of dual-core processors is the 600 series. This series today includes two models: Phenom II X620 BE and Phenom II N620. Both of them have a 2 MB L2 cache (1 MB per core) and 3600 GT/s HT bus bandwidth. Moreover, both processor models support DDR3-1333 memory (MAX CPU BW is 35.7 GB/s). The difference between the processors is that the Phenom II X620 BE model has a power consumption of 45 W and a clock speed of 3.1 GHz. In addition, this processor has an unlocked multiplier. The Phenom II N620 processor with a power consumption of 35 W has a clock speed of 2.8 GHz.

Concluding the review of mobile processors of the Phenom II family, we note once again that it includes four, triple and dual-core processors with a 128-bit FPU, the power consumption of which can be 45, 35 or 25 W. All of these processors have HT 3600 GT/s bus bandwidth and support DDR3 memory with a maximum frequency of 1333 or 1066 MHz. The size of the L2 cache depends on the number of processor cores and per one processor core is 512 KB (for four and three-core models) or 1 MB (for dual-core models).

The next family of 45nm mobile processors based on the Champlain core is the Turion II family of dual-core processors, which is represented by two models: Turion II N530 and Turion II P520. These processors differ from each other only in clock speed and power consumption. The Turion II N530 has a clock speed of 2.5 GHz and a power consumption of 35 W, while the Turion II P520 has a clock speed of 2.3 GHz and a power consumption of 25 W. In all other respects, the characteristics of these processors are the same. Thus, both models are equipped with 128-bit FPUs, have a 2 MB L2 cache (1 MB per core), and the HT bus bandwidth is 3600 GT/s. In addition, both processor models support DDR3-1066 memory. Note that dual core processors The characteristics of the Turion II 500 series family are practically no different from the dual-core models of the Phenom II 600 series processor family. The differences are only in the clock speed and the maximum frequency of supported memory. Actually, it’s not very clear why these two processor models needed to be separated into a separate Turion II family, because they could be classified as part of the Phenom II family of dual-core processors.

The next family of AMD dual-core mobile processors based on the Champlain core is the Athlon II family, which is also represented by two models: Athlon II N330 and Athlon II P320. These processors are really very different from the dual-core Phenom II and Turion II processors. First of all, their L2 cache is reduced to 1 MB (512 KB per core). In addition, these processors have 64-bit FPUs and an HT bus bandwidth of 3200 GT/s. In addition, these processors only support DDR3-1066 memory. The differences between the Athlon II N330 and Athlon II P320 models themselves are in clock speed and power consumption.

Single-core mobile processors based on the Champlain core are represented by the V-Series family, which today includes only one model - the V120 with a clock frequency of 2.2 GHz and a 512 KB L2 cache. This processor is equipped with 64-bit FPUs, and the HT bus bandwidth is 3200 GT/s. In addition, the V120 processor supports DDR3-1066 memory and its power consumption is 25 W. In general, according to its characteristics, the V120 processor is a single-core version of the Athlon II P320 processor.

All of the AMD mobile processors we reviewed are 2010 processors (the company announced them in May) aimed at performance, general purpose, and entry-level laptops. However, AMD's product range also includes processors with reduced power consumption - they are aimed at ultra-thin laptops and netbooks. These dual-core and single-core 45nm processors, also announced in May, are codenamed Geneva and include the Turion II Neo, Athlon II Neo and V-Series

Dual-core processors of the Turion II Neo series (Turion II Neo K665, Turion II Neo K625) have a power consumption of 15 W, dual-core and single-core processors of the Athlon II Neo series (Athlon II Neo K325, Athlon II Neo K125) have a power consumption of 12 W, but the power consumption of a single-core The V105 processor is only 9 Watts.

The Turion II Neo series dual-core processors feature 128-bit FPUs and 2 MB L2 cache (1 MB per core). The HT bus capacity is 3200 GT/s.

Athlon II Neo series processors have 64-bit FPUs and 1 MB L2 cache per core, and HT bus bandwidth is 2000 GT/s. Well, the single-core V105 processor differs (except for the clock frequency) from the single-core Athlon II Neo K125 processor in that the L2 cache is halved.

Note that all Geneva processors support DDR3-1066 memory in dual-channel mode.

In addition to the Champlain and Geneva mobile processors, AMD's product range also includes other 45 nm mobile processors. We are talking about processors codenamed Caspian, which were announced in September 2009 and are not yet outdated. Caspian mobile processors are represented by the Turion II and Turion II Ultra dual-core processor families, the Athlon II dual-core processor family, and the Sempron single-core processor family.

All dual-core Caspian processors have a power consumption of 35 W, and single-core processors have a power consumption of 25 W. In addition, all Caspian processors only support DDR2-800 memory (in dual-channel operating mode).

The Turion II and Turion II Ultra processor families feature 128-bit FPUs and HT bus bandwidth of 3600 GT/s. The difference between the Turion II Ultra and Turion II family of processors is that the Turion II Ultra processors have a 2 MB L2 cache (1 MB per core), while the Turion II processors have a 1 MB L2 cache (512 KB per core).

Processors of the Athlon II and Sempron families have 64-bit FPUs and 512 KB L2 cache per core. In addition, the HT bus bandwidth for these processors is 3200 GT/s.

This article will compare laptop processors from two leading semiconductor manufacturers - Intel and AMD. The products of the first of them are equipped with an improved processor part and in this regard have a higher level of performance. In turn, AMD solutions boast a more powerful graphics subsystem.

Division into niches

Comparison and Intel for laptops would be best done in three niches:

• Budget-class processors (they are also the most affordable).
• Mid-level CPUs that combine both high speed and acceptable energy efficiency.
• Chips with maximum performance levels. In this case, performance, autonomy and energy efficiency fade into the background.

If in the first two cases AMD can provide a worthy alternative to Intel, then the latter company has reigned supreme in the premium segment for quite some time. The only hope in this regard is new processor solutions based on the Zen architecture, which AMD should present next year.

Entry-level Intel products

Until recently, this niche from Intel was occupied by products from the Atom line. But now the situation has changed and entry-level laptops are now based on processors. The most modest products in this class include only 2 cores, and the most advanced - 4. The following models are relevant for the 3rd quarter of 2016, which are shown in Table 1.

Table 1 - Current models Intel CPU for entry-level mobile PCs.

There are essentially no fundamental differences between these CPU models. They are aimed at solving the simplest problems and have a minimum level of performance. Also, this manufacturer of semiconductor solutions has a strong point in the processor part, but the integrated graphics subsystem is very weak. Another strength of these products is the high degree of energy efficiency and the resulting improved autonomy.

Mid-range solutions from Intel

Core i3 and Core i5 are mid-range Intel processors for laptops. A comparison of their characteristics indicates that the first family is closer to entry-level solutions, and the second, under certain circumstances, can compete with the most productive chips of this company. Detailed specifications of this product family are given in Table 2.

Table 2 - Parameters of Intel processors for mid-range laptops.

The characteristics of CPUs of this class are almost identical. The key difference is the improved energy saving of the 7U54. As a result, autonomy in this case will also be better. Otherwise, there are no significant differences between these processors. The price for all chips of this family is the same - $281.

Premium processors for laptops from Intel

For the latest generation laptops, this indicates that the most powerful solutions include i7 family CPUs. Moreover, in architectural terms, they are practically no different from middle-class products. Even the video card models in this case are the same. But a higher level of performance compared to mid-range processors is provided by higher clock speeds and an increased size of Level 3 volatile memory. The main parameters of chips of this family are shown in Table 3.

Table 3 - Main characteristics of i7 family CPUs.

The difference between these products is that in the second case, energy efficiency is improved, but the performance will ultimately be lower.

AMD entry-level mobile processors

For laptops from the two leading manufacturers of these products, it indicates that Intel, as noted earlier, has a better processor part, and AMD has an integrated graphics subsystem. If the priority in a new laptop is an improved video system, then it is better to pay attention to laptops from a second manufacturer. Specific Models chips technical specifications are given in Table 4.

Table 4 - The latest AMD processors for entry-level laptops.

For the most part, these chips have almost identical technical specifications. The key difference here is only in the frequency range and the model of the integrated built-in accelerator. It is based on these parameters that you need to make a choice. If you need maximum autonomy, then we choose products with lower performance. If autonomy comes to the fore, then you will have to sacrifice dynamism for this.

AMD chips for organizing mid-range laptops

FX-9XXXP and A1X-9XXXP are for laptops. Comparison of their characteristics with entry-level products indicates that they already have 4 computing units versus 2, which are available in entry-level products. Also in this case it can be a worthy competitor to entry-level discrete accelerators. But the weak processor part is the factor today that significantly reduces the performance of laptops based on these chips. Therefore, you can only look in their direction when minimum cost A mobile computer needs the fastest possible graphics subsystem. The main specifications of this CPU family are listed in Table 5.

Table 5 - AMD CPU parameters for mid-range laptops.

The hardest comparison to make between laptop processors is in the entry-level product segment. On the one hand, Intel solutions in this case have a lower cost and an improved processor part. In turn, AMD offers mobile PCs with an improved graphics subsystem. Precisely starting from last parameter and is recommended to buy when choosing an entry-level laptop Pavilion 15-AW006UR from HP. All other things being equal to competing solutions, the video card in this case will have a certain performance margin, and the processor is not that much inferior to the Intel CPU. For a mid-level mobile PC, it is recommended to choose the Aspire E5 - 774 - 50SY from Acer. It has an i5 chip installed - 7200U, which is only slightly inferior to flagship products. Yes and others technical specifications It's at an acceptable level for a mid-class laptop. Comparison of laptop processors in the niche of the most productive solutions indicated which is best to buy mobile computers based on 7th generation i7 chips. The most affordable, but also very equipped laptop option is the IdeaPad 510-15 IKB from Lenovo. This is what we recommend buying when choosing the most productive mobile PC. At the same time, the price is quite affordable for this class of devices, and the equipment is excellent.

Results

A comparison of laptop processors from two leading chip manufacturers today clearly and clearly indicates that in most cases the leading positions are occupied by products from Intel. AMD, in turn, lags significantly behind its direct competitor. The only market segment where parity is still maintained is entry-level mobile products, where AMD has a worthy alternative. In all other cases, it would be more correct to purchase laptops based on Intel CPUs. The current situation can be radically changed by the release of processors based on the Zen architecture in 2017. But whether AMD will be able to do this - time will tell. Now, in the niche of mid-level and premium mobile PCs, it is most correct to rely on solutions from Intel. Although their price is somewhat high, the level of performance more than compensates for this shortcoming.
