next-gen CPUs are coming

AMD has just unveiled the first Ryzen 7000 models, its new processors for desktop PCs. Taking advantage of the new Zen 4 architecture and 5 nm engraving, these powerful CPUs outperform the latest flagships from Intel.

We have been waiting for them for months. They finally arrived! AMD recently presented the first Ryzen 7000 models, its new generation of processors for fixed PCs. At a conference held on August 30, Lisa Su, the CEO of the American company, officially introduced four CPU models – – the Ryzen 5 7600X, Ryzen 7 7700X, Ryzen 9 7900X and Ryzen 9 7950X – which will hit the market on September 27, 2022 to inaugurate the new range. Beyond their impressive technical characteristics, but already known through leaks, these new chips promise unprecedented performance, surpassing the best Intel processors today, the famous Alder Lake. Enough to relaunch the great race for power, and, above all, to satisfy the most demanding users, for gaming as well as for digital creation.

Ryzen 7000: four models from 6 to 16 cores

After several weeks of leaks and rumors, we know the list of the first representatives of the Ryzen 7000 family, all based on the same architecture (see below). Touted to gradually replace the current Ryzen 5000 in desktop PCs, they will be added to other models in the coming months. Here is a summary of the main technical characteristics and the prices of the new ones.

  • Ryzen 5 7600X: 6 cores, 12 threads, 4.7GHz/5.3GHz, 38MB L2+L3 cache, 105W TDP, $299
  • Ryzen 7 7700X: 8 cores, 16 threads, 4.5GHz/5.4GHz, 40MB L2+L3 cache, 105W TDP, $399
  • Ryzen 9 7900X: 12 cores, 24 threads, 4.7GHz/5.4GHz, 76MB L2+L3 cache, 170W TDP, $549
  • Ryzen 9 7950X: 16 cores, 32 threads, 4.5GHz/5.7GHz, 80MB L2+L3 cache, 170W TDP, $699

As we can see, AMD is careful to conduct its range well, in terms of the number of cores – and therefore power – and price, the numbering using the same principle as previous generations. Be careful, however, because, as always with American products, the prices shown are for the United States, and therefore do not include tax. The rates in Europe, and therefore in France, will be greatly increased, partly by the exchange rate, not in favor of the euro at the moment, and by the 20% VAT. The good news is that despite component shortages and inflation, AMD hasn’t raised its Ryzen 5000s prices.

Beyond the technical characteristics, it is above all the performance improved by AMD that caught the attention during the official presentation. Especially since AMD is not just talking about children compared to the previous generation Ryzen: the American dares to face the latest generation Intel chips, the famous Alder Lake, but already very efficient. Even better, AMD pushed the envelope to put the “weakest” model, the Ryzen 5 7600X, in front of Intel’s flagship. And “small” should not be ashamed of the comparison, competing toe to toe with the Core i9-12900K!

Against Intel’s best processor, the Core i9-12900K, AMD claims up to 11% performance gains in single-core and 44% in multi-core for its Ryzen 9 7950X, with up to of 47% more performance in the watt used, resulting in particular from the design of the 5 nm technology.

AMD: a return to grace

AMD has clearly returned to the forefront of the computing scene in recent years. And intend to stay that way! Thus, after a long period of slowness in which it was far behind Intel with unattractive processors, the American company was able to bounce back and even lead the technological race with the famous Ryzen, the CPU with a performance / price ratio is particularly useful. which has enjoyed rousing success, to the point of becoming a staple for gamers, always fond of computing power. And if Intel, hit by its pride, was able to close the gap compared to its eternal competitor in the Core 12 family.e generation, known as Alder Lake (see our article), some of whose representatives claim the best places in the benchmarks, AMD intends to regain the advantage with the new Ryzen 7000 range that should arrive in the fall of 2022.

So, while rumors and leaks have been increasing for several months, AMD took advantage of the opening of the Computex 2022 trade show in Taiwan to officially present its future processors for fixed PCs. Next-generation and decidedly high-end CPUs benefit from many improvements over current models of the already high-performance Ryzen 5000 series. But also compared to the chips of the recent Ryzen 6000 Mobile family, which are intended for laptops.

Ryzen 7000: new generation CPUs with Zen 4 architecture

On a technical level, the Ryzen 7000 processors – which, like all, are available in several versions – will inaugurate a new architecture, Zen 4, which will succeed the current one, Zen 3 through bring many improvements at the level of the internal organization. Ryzen 7000s, which can have up to 16 physical cores and 32 logical cores (for parallel processing, threads), will be built on a relatively smart hybrid structure consisting of two parallel chiplets etched in 5 nm technology and an input module -outputs (I). /O) is manufactured in 6 nm technology, taking advantage of new techniques developed by TSMC, the famous specialist in electronic circuits – which also manufactures Apple’s M1 chips, among others. By going from 7 nm engraving, which is used for the Zen 3 architecture of the current best Ryzen 5000s, to the excellence of 5 nm, AMD should be able to integrate more transistors in its calculation units while optimizing power consumption. An advantage against Intel, which still uses 10 nm technology in its Core 12e generation – which does not prevent them from offering excellent performance – but not compared to Apple which has moved to 5 nm in its M1 chips.

In practice, the Zen 4 architecture makes it possible to increase the level 1 cache of each core, which goes from 512 KB to 1 MB in the Ryzen 7000. It may not be as much, but this ultra-fast memory, which located inside the chip itself, making it possible to speed up processing. In addition, without giving details, AMD promises that the Ryzen 7000 will exceed 5 GHz in turbo mode, during intensive calculations. During his demo presentation on stage, AMD boss Lisa Su showed off a 16-core Zen 4 model clocked at 5.5 GHz. An impressive frequency that should allow these new CPUs to offer very high performance. However, it is difficult to know what these improvements will provide in a real situation, since AMD remains somewhat vague at this point, limiting itself to the stimulation of a relatively modest which is a gain of 15% for single-core operations. (a thread), but neither the reference model nor the measurement conditions are specified. It is expected that the Ryzen 7000s will mark many differences in reality, including operations using multiple cores (multi-threaded) to justify their next-generation high-end status and be ahead of the latest Intel chips…

Ryzen 7000: DDR 5 and PCIe 5.0 for high performance

Of course, the Ryzen 7000s brings many other new features compared to the generation of 5000. To the point that AMD has to change the type of support (socket) that can accommodate them on motherboards. Therefore, the AM4 format introduced in 2017 and used by the current Ryzen will give way to AM5. Main consequence: the obligation to install Ryzen 7000 on new motherboards, with no possibility to recover the current ones. As a consolation, AMD ensured that the metal cover (the IHS) of the Ryzen 7000s remains compatible with cooling devices designed for socket AM4. If there are no savings – you still have to buy a processor, motherboard and RAM… – this will allow you to have a choice when these CPUs arrive. However, be careful, because the maximum TDP (the thermal envelope) is from 105 W to 170 W. It is expected that the CPUs will increase the temperature significantly during heavy operation.

Another notable new feature: RAM. The Ryzen 7000s actually handles DDR5, the new generation of Ram that offers much higher speeds than the DDR4 currently used in all PCs today. In the same vein, they also support the PCIe (PCI Express) 5.0 standard instead of PCIe 4.0, which also offers a higher transfer rate, which will allow you to take advantage of the new generation of high-performance SSDs. .

Who said the new support also said the new chipset, the “set of chips” that manages the processor and other elements of motherboards. AMD designed three new ones: the B650, the X670 and the lX670E, which are intended for entry-level, mid-range and high-end PCs. We should see that they come quickly with motherboards from specialists such as Asus or MSI.

iGPU: RDNA 2 as standard on all Ryzen 7000s

In addition, it seems that unlike Ryzen 5000s, all Ryzen 7000s are equipped as standard with an integrated graphics circuit (an iGPU as it is called), avoiding the use of a dedicated graphics card, except for most requested. players. And this is not a discounted section because this module can be of the RDNA 2 type, that is to say the technology found in the Ryzen 6000 but also the Steam Deck hybrid console or the essential Xbox Series and the PS5, equipped on the AMD chip standard. . True, due to the lack of details, we still do not know the number and frequency of graphic cores that will be integrated. But since an RDNA 2 core is up to twice as powerful as a Radeon Vega core, we can expect a very good level of performance, not to mention reduced power consumption compared to a graphics card. Enough to be more than enough for most applications, including 3D in most games, which is no less an asset in these times of component shortage…

At the moment, we do not know the exact composition of the Ryzen 7000 family, which will obviously develop slowly, like all other ranges. We only know that AMD plans to release them in the fall of 2022. And we can imagine that the brand will distill other information on the launch date. So we have to wait a bit to know more about other technical aspects, but also, and above all, about the actual performance and prices. And this last point is especially sensitive when we know that TSMC has decided to increase its prices. Let’s meet in a few months to see what the new AMD champions are really worth against the competition, because we suspect that Intel will not remain inactive. And that Apple is also preparing new ARM architecture chips that are even more impressive than the current M1s. Undoubtedly, after a few years of relative calm, the processor war is off to a good start!
