Second generation AMD Ryzen

Second generation AMD Ryzen

Ryzen 2nd Gen is not Ryzen 2

Leaks on the new CPU from AMD, the updated Ryzen line, have been circulating on the Web for quite some time – in fact, it’s not even streamlets, but full-flow information flows. About Ryzen 2nd Gen it was known, it seems, almost all before the official announcement – but nonetheless, it was very interesting to receive first-hand information subsequent to the presentation of AMD, which the company held on April 2018 in Munich. Let share about the announcement in details.

So, Ryzen 2nd Gen is not Ryzen 2, we are still waiting for its appearance (maybe next year?), This is the updated and improved “first” Ryzen, built on the Zen + architecture. But – in order. First in front of journalists was Jim Anderson, senior vice president and general manager of the computer and graphics systems division of AMD.

Ryzen 2nd Gen is not Ryzen 2

He began “from afar” – he remembered the first Ryzen release in 2017 and how he influenced the market (read: forced Intel to move), and that in addition to twenty different Ryzen processors of the first generation, AMD then also released a powerful Radeon RX Vega GPU and a line of processors for servers EPYC – according to Jim, the release of three products of this level within one year means that AMD is returning to high-performance “computing”. In support of these words, he recalled the first desktop 16-core Ryzen Threadripper, as well as Ryzen Mobile, which appeared at the end of the year, in which, quote, “Zen Meets Vega”, which allowed obtaining high gaming performance in thin laptops without a discrete video card his words,

And naturally, he could not resist the hairpin to Intel, mentioning the “Ryzen effect”: “The competition of manufacturers is always good for the consumer, see – Intel had 10 cores in desktop systems for 10 years, but after the appearance of the eight-core AMD Ryzen 7 1800X suddenly there were six; for thin notebooks Intel has offered dual-core processors since 2010, and after the release of AMD Ryzen 7 2700U and Intel also suddenly appeared kvadkory.

2018, says Jim, should become even more productive for AMD – Ryzen CPUs with Vega graphics have already managed for both ultra-thin laptops and desktop systems. In the coming months, mobile Ryzen PRO is expected, again with Vega, in the second half of the year – the second generation of Ryzen PRO for business and Ryzen Threadripper for “ultimate” desktop systems with maximum performance; and, of course, today’s official exit of the protagonist of this presentation is Ryzen 2nd Gen, performed on a 12 nm process technology, the first processor on the Zen + architecture.

So, the flagship processor in the second generation of “raizen” is Ryzen 7 2700X: the base clock speed is 3.7 GHz (4.3 GHz in Max Boost mode), 20 MB cache, 8 cores and 16 streams, it comes with a proprietary cooler Wraith Prism, the recommended cost is $ 329. The younger version of this processor, without the X index, costs $ 30 less – it’s just below the frequency (3.2 GHz / 4.1 GHz), the same number of cores and threads, the same cache size, and the simpler complete cooler Wraith Spire. Also in the second generation, there are two versions of the Ryzen 5 2600: the older 2600X (6 cores, 12 streams, 19 MB cache, 3.6 GHz / 4.2 GHz frequencies, recommended price $ 229) and the younger one, down to 3.4 GHz / 3.9 GHz frequencies, priced at $ 199.

The rest of the presentation was built primarily against Intel’s competitive models, and the main idea was “the same performance in games, the higher in application applications, all for less money, plus a cool cooler included.”

So, according to Jim Anderson, the second generation Ryzen shows itself much better in multi-threaded computing – editing photo, video, audio and other typical tasks for the average user is performed on average 20% faster than on the “analog from Intel.”

In more detail on performance and other technical details, the next speaker was the speaker – Joe Macri, technical director of AMD’s customer direction.

According to him, when developing the updated Zen + architecture on which the second generation AMD Ryzen is based, special attention was paid to reducing memory access delays: compared with Zen, the new architecture can boast 11% less latency of access to RAM, at ~ 15 % – to the cache memory of the first and third levels, and a third smaller – to the cache memory of the second level. As a result, it allowed getting higher performance in single-threaded computations (3% more instructions per cycle than Zen).

In addition, the transition of GlobalFoundries (chip manufacturer for AMD) to a new 12-nm process technology allowed raising the maximum frequencies by ~ 250 MHz, and the overclocking of all cores can now reach 4.2 GHz, with the voltage at similar frequencies being lower by an average of 50 mV per compared with the first generation Ryzen. In more understandable numbers, the benefit of switching to 12 nm sounds like this: up to 11% less power consumption at the same frequencies, or up to 16% higher performance with the same TDP.

To get the maximum possible performance in each particular task, the updated technology Precision Boost 2, included in the proprietary “set” of AMD SenseMI, is called for. With its help, the system automatically raises the processor frequency to a certain safe maximum value, if it “sees” for this the need and possibility (taking into account the ambient temperature, supply voltage, etc.). And if the first version of Precision Boost operated only two concepts of “1-2-load load” and “load of 3 or more threads” (in the second case, immediately limiting the maximum possible frequency), Precision Boost 2 offers a linear schedule for reducing the maximum frequency in depending on the number of threads, which allows the processor to operate at higher frequencies in case of incomplete download (but exceeding two threads).

If we talk about the performance of new processors compared to the solutions from the competitor – according to AMD measurements, in multi-threaded calculations, the Ryzen 7 2700X is an average of ~ 21% faster than the Intel Core i7 8700K in popular benchmarks and application applications like Cinebench R15, Blender, Handbrake and etc.

In games, of course, the situation is different, AMD refers to the indicators of these two processors as “practically identical”, showing on the diagrams own results in a dozen popular gaming benchmarks in 1080p and 1440p (which differ little from each other, and not always in favor of Intel). Practically similar indicators in applications and games are shown for the younger “couple” – AMD Ryzen 5 2600X vs Intel Core i5 8600K. As summarized by this part of Joe Macri’s presentation, “the player is unlikely to understand on whose system he is playing – ours or Intel, because if there is a performance difference, it is so small that an ordinary person will not notice it.”

And the last, the third speaker that evening was Travis Kirsch, director of customer management for AMD. He told how important the company’s opinion is to the users, to which they listen very carefully – so in the second generation, Ryzen AMD, as before, uses solder: according to the company, this allows to reduce the temperature regime by at least 10 degrees compared to the thermal paste. This is good news for overclocking enthusiasts – as well as the fact that all the processors of the second generation Ryzen have a multiplier unlocked. Also on the enthusiasts are focused and complete coolers Wraith series, which are very different from what we used to call “box” – for example, the older, Prism (coming with the flagship Ryzen 7 2700X), direct contact of the heat pipes with the processor, the noise level does not exceed 39 dB, there is support for switchable fan speed profiles,

Separately, Travis mentioned the proprietary utility for overclocking AMD Ryzen Master, which is the new version 1.3 has learned to give extended information on the features of the motherboard, has received a built-in stability test, etc. All this taken together, summed up Travis, makes overclocking of the new Ryzen processors very simple and at the same time effective.

AMD offers Ryzen 2nd Gen processors within the existing Socket AM4 platform (its support is planned until at least 2020), which allows to keep compatibility with motherboards that have already been released (for which a BIOS update will be required – either it must be done on its own or “search in selling motherboards on the chipsets of the 300 series with the sticker AMD Ryzen Desktop 2000 Ready “).

Also, Travis Kirsch told about the new top-end chipset AMD X470 – motherboards based on it will receive an optimized power scheme for overclocking the processor, support for memory modules with a higher frequency and reduced power consumption in idle mode. In addition, the X470 supports AMD StoreMI technology, which combines all drives, SSDs and HDDs, into a kind of “pool” (adding up to 2 GB of RAM) and creates a single logical drive that speeds up the operating system and the launch of installed games (StoreMI automatically transfers the most frequently used files to the fastest drive in the system). Theoretically, this should help in the case when a relatively small system SSD is installed in the computer, and all games and applications are on a more capacious and slow HDD (according to the data announced by AMD,

This formal part of the presentation came to an end, and further communication with representatives of the company passed into a less formal plane – AMD arranged a kind of friendly “championship” among journalists on overclocking, having organized several stands with new processors with different cooling systems (both air and water, as well as with his own Wraith Prism). The organizers themselves undertook to show what the Ryzen 7 2700X is capable of under nitrogen – and at the end of the event, it was able to overclock it to almost 5.7 GHz.

This was, so to speak, a “correspondence” acquaintance with the second generation AMD Ryzen, in the near future we plan to publish our review of these processors, with detailed information and our own tests.
