AMD has just introduced the first Ryzen 7000 models, its new desktop PC processors. Leveraging the new Zen 4 architecture and 5nm etching, these powerful CPUs outperform the latest Intel flagships.
We have been waiting for them for several months. They finally arrive! AMD has just introduced the first models of Ryzen 7000, its new generation processors for fixed PCs. At a conference held on August 30, Lisa Su, CEO of the American company, officially presented four CPU models: 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 its impressive technical characteristics, but already known via leaks, these new chips promise unprecedented performance, even surpassing the best current Intel processors, the famous Alder Lake. Enough to relaunch the great race for power and, above all, to satisfy the most demanding users, both gaming and 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). Called to gradually replace the current Ryzen 5000 in desktop PCs, they will be complemented by other models in the coming months. Here you have 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 has taken care to stage its range well, both in number of cores -and therefore power- and in price, following the same numbering principle as in previous generations. However, be careful because, as always with American products, the prices indicated are for the United States and, therefore, without taxes. The rates in Europe, and therefore in France, will be notably increased, on the one hand by the exchange rate, currently unfavorable to the euro, and by the 20% VAT. The good news is that despite component shortages and inflation, AMD hasn’t raised its prices above the Ryzen 5000.
Beyond the technical features, it is above all the performance advanced by AMD that caught the eye during the official presentation. Especially since AMD was not only talking about children compared to the previous generation Ryzen: the American dared to face the latest generation Intel chips, the famous Alder Lake, but already very efficient. Better yet, AMD has pushed the envelope to put its “weakest” model, the Ryzen 5 7600X, up against Intel’s flagship. And the “small” need not be ashamed of the comparison, competing foot to foot with the Core i9-12900K!
Compared to the best Intel processor, the Core i9-12900K, AMD claims up to 11% single-core and 44% multi-core performance increase for its Ryzen 9 7950X, with up to 47% more performance per watt consumed, resulting in a particular design result in 5nm technology.
AMD: a return to grace
AMD has clearly returned to the forefront of the computing scene in recent years. And he intends to keep it that way! Thus, after a long period of hiatus in which it was far behind Intel with unattractive processors, the American company was able to rebound and even lead the technological race with its famous Ryzen, CPUs with a performance/price ratio especially advantageous. that have reaped enviable success, to the point of having become a benchmark for gamers, always fans of computing power. And if Intel, struck in its pride, was able to close the gap with respect to its eternal competitor with its Core 12 familyme generation, known as Alder Lake (see our article), some of whose representatives claim the best places in the benchmarks, AMD intends to regain the upper hand with its new Ryzen 7000 range that should arrive in the fall of 2022.
Thus, while rumors and leaks have abounded for several months, AMD took advantage of the opening of the Computex 2022 fair in Taiwan to officially present its future processors for fixed PCs. Next generation and decidedly high-end CPUs that will benefit from several improvements over the current models of the already high-performing Ryzen 5000 series. But also compared to the chips of the recent Ryzen 6000 Mobile family, intended for laptops.
Ryzen 7000: new generation CPUs with Zen 4 architecture
On a technical level, the Ryzen 7000 processors -which, like all the others, will be available in multiple versions- will launch a new architecture, Zen 4, which will succeed the current one, Zen 3, bringing several improvements at the internal organization level. The Ryzen 7000, which can have up to 16 physical cores and 32 logical cores (for parallel processing, threads), will be built on a fairly clever hybrid structure made up of two identical chiplets embossed in 5nm technology and an input-output module. (I / O) manufactured in 6nm technology, taking advantage of new techniques developed by TSMC, the great specialist in electronic circuits -which also manufactures Apple’s M1 chips, among many others-. Going from the 7nm etching, used for the Zen 3 architecture of the current top Ryzen 5000, to a fineness of 5nm, AMD should be able to integrate more transistors into its compute units and optimize power consumption. An advantage over Intel, which continues to use 10nm technology in its Core 12me generation -which does not prevent them from offering excellent performance-, but not compared to Apple that has already gone to 5nm in its M1 chips.
In practice, the Zen 4 architecture allows each core’s level 1 cache to be increased from 512 KB to 1 MB on a Ryzen 7000. It may not seem like much, but this ultra-fast memory, located inside the chip itself, allows significantly speed up processing. Also, without giving details, AMD promises that the Ryzen 7000 will exceed 5 GHz in turbo mode, during intensive calculations. During her demo presentation on stage, AMD boss Lisa Su demoed a 16-core Zen 4 model that maxes out at 5.5GHz. An impressive frequency that should allow these new CPUs to deliver a very high performance. However, it’s hard to know what these improvements will do in a real world situation, because AMD remained relatively vague on this point, limiting itself to evoking a relatively modest 15% gain for single-core operations. (single thread), but without specifying the reference model or the measurement conditions. It is to be expected that the Ryzen 7000 will make more of a difference in reality, even in multi-core operations (multithreaded) in order to justify its next-gen high-end status and take precedence over the latest Intel chips…
Ryzen 7000: DDR 5 and PCIe 5.0 for high performance
Of course, the Ryzen 7000 brings many other novelties compared to the 5000 generation. To the point that AMD had to change the type of support (socket) that will accommodate them on motherboards. Thus, the AM4 format introduced in 2017 and used in the current Ryzen will give way to AM5. Main consequence: the obligation to install the Ryzen 7000 on new motherboards, without the possibility of recovering the current ones. As a consolation, AMD has ensured that the Ryzen 7000’s Metal Shroud (IHS) remains compatible with cooling devices designed for socket AM4. Short of savings – you’ll still have to buy a processor, motherboard and RAM… – this will give you plenty of choice as soon as these CPUs arrive. Be careful though, because the maximum TDP (the thermal envelope) ranges from 105 W to 170 W. Expect CPUs to get significantly hotter during heavy operations.
Another notable new feature: RAM. In fact, the Ryzen 7000 handles DDR5, the new generation of Ram that offers much higher speeds than the DDR4 currently used in all current PCs. Along the same lines, they also support the PCIe (PCI Express) 5.0 standard instead of PCIe 4.0, which also offers higher transfer rates, allowing you to take full advantage of the new generation of high-performance SSDs.
Who says new support also says new chipset, the “chipset” that manages the processor and the other elements of the motherboard. AMD has designed three new ones: the B650, the X670 and the lX670E, aimed respectively at entry-level, mid-range and high-end PCs. We should see them quickly find their way to motherboards from specialists like Asus or MSI.
iGPU: RDNA 2 as standard on all Ryzen 7000
In addition, it seems that unlike the Ryzen 5000, all Ryzen 7000 come equipped with an integrated graphics circuit (an iGPU as they are called) as standard, which avoids the use of a dedicated graphics card, except for the most demanding. players And it will not be a discounted section since this module will be of the RDNA 2 type, that is, the technology found in the Ryzen 6000 but also the Steam Deck hybrid console or the essential Xbox Series and the PS5, equipped with a standard AMD chip. . It is true that, due to lack of details, we still do not know the number and frequency of the graphics 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 separate graphics card. Enough to be more than enough for most applications, including 3D in most games, which is no less valuable in these times of component shortage…
At the moment, we do not know the exact composition of the Ryzen 7000 family, which will obviously evolve gradually, like all the other ranges. We only know that AMD plans to launch them in the fall of 2022. And we can imagine that the brand will distill other information for the launch date. We will therefore have to wait a little longer to find out more about the 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. See you in a few months to see what the new AMD champions are really worth against the competition, as we suspect that Intel will not sit idle. And that Apple is also preparing new ARM architecture chips that are even more impressive than the current M1. Without a doubt, after a few years of relative calm, the processor wars are off to a good start!
