AMD had already repeatedly mentioned its new generation of processors for desktop computers. Succeeding the Ryzen 5000 launched just under two years ago, the Ryzen 7000 inaugurate a new platform called AM5: the previous Ryzen were based on an AM4 platform that will have had the merit of being used for 5 years. Under the body, AMD is now using the fourth revision of its Zen architecture with the promise of significantly improved power efficiency.
First of all, let’s remember that the Ryzen 7000 are the first AMD consumer processors to benefit from 5nm etching. This allows the number of transistors per mm² to be increased but also power consumption to be reduced, resulting in much higher clock rates than the Ryzen 5000 with a maximum peak of 5.7 GHz when cooling conditions are optimal.
AMD thus indicates that the performance of a single core increases by 13% on average at the same frequency and up to 44% in applications taking advantage of all the cores. Enough to outperform 12th Gen Intel Core chips in both gaming and apps according to AMD, but this generation of Ryzen processors will eventually go into battle against 13th Gen Cores, let’s keep that in mind. AMD thus puts the example of 3D rendering in raytracing, executed 57% faster on a Ryzen 9 7950X than on a Core i9-12900K. In games too, AMD is confident, saying a “simple” Ryzen 5 7600X would be faster than a Core i9-12900K, with an average 5% advantage over a selection of AMD-made games.
At launch, only four references will go on sale: the Ryzen 5 7600X (6 cores), the Ryzen 7 7700X (8 cores), the Ryzen 7 7900X (12 cores), and the Ryzen 9 7950X (16 cores). We notice that the number of cores does not change compared to the Ryzen 5000, which does not happen with the power consumption. Thus, the Ryzen 9 7950X and 7900X are given for a maximum of 170 watts, when the Ryzen 9 5950X was content with 105 watts. A funny situation, AMD has never stopped making fun of 12th Gen Cores for their high power consumption. A curious choice moreover, this unlocking certainly makes it possible to reach a higher frequency, but at the cost of the need to use a very efficient and therefore quite expensive cooling system.
However, AMD assures us, this series of processors offers eminently better energy efficiency than the competition, that is, that of the 12th generation Intel Core chips. Thus, the architectural changes and the use of 5nm engraving allow the firm to advance quite favorable figures such as the use of a chip that is approximately 50% smaller and that offers approximately 47% greater energy efficiency. Other interesting data, the Ryzen 7000 would consume 62% less power than the Ryzen 5000 with equivalent performance or 49% more performance with similar power consumption.
Regarding the AM5 platform -which will be used at least until 2025- itself, the new socket has the good taste of using the same fixing system as the AM4 socket. This allows current cooling systems to be fully compatible with new motherboards. With the AM5, AMD has provided a design that will be able to handle a maximum load of 230 watts, leaving room for the manufacturer to overclock or possibly more power-hungry chips.
At the moment two chipsets are planned, each declined in Extreme versions, thus for a total of 4 chipset references. High-end motherboards will be based on the use of X670 Extreme or X670 chips and entry-level versions will be based on B650 Exteme and B650 chips. Both chipsets will result in similar performance, but the X revisions will offer more freedom for overclocking. As for the difference between the Extreme and Classic versions, this is PCIe 5, which will be limited to graphics card support in the Classic versions, while you can mix graphics cards and SSDs in the Extreme versions. The opportunity also for AMD to announce that PCIe 5 SSDs are not expected until November.
On the memory side, it will be exclusive support for DDR5. Although it is still much more expensive than DDR4, AMD expects the two technologies to be sold at the same price by the end of the second half of 2023. This support for DDR5 is accompanied by a new technology called AMD Expo that will allow memory to be overclocked with a single click through to a specific application. A novelty that, however, is not exclusive, Intel offers similar functionality in its 12th generation Core.
Regarding prices, only prices in dollars have been communicated to us; French prices will be published shortly. Therefore, it is necessary to count $299 for the 7600X, $399 for the 7700X, $549 for the 7900X and $699 for the 7950X. Prices quite close to those charged by the Ryzen 5000 at launch. Availability is scheduled for September 27 and there is no doubt that AMD will provide more technical details about its new platform, its new features or even the overclocking capabilities of its chips by then. In the process, Intel should give more details about its 13th generation of Core processors. The start of the school year promises to be busy.
