AMD repeatedly talks about the new generation of processors for desktop computers. Succeeding the Ryzen 5000s that were released less than two years ago today, the Ryzen 7000s ushered in a new platform called AM5 – the previous Ryzens were based on an AM4 platform that had the merit of being used in in 5 years. Under the bodywork, AMD is now using the 4th revision of the Zen architecture with the promise of significantly improved energy efficiency.
First of all, let’s remember that the Ryzen 7000 is the first consumer processor from AMD to benefit from 5 nm engraving. This makes it possible to increase the number of transistors per mm² but also to lower energy consumption, producing higher frequencies than the Ryzen 5000s with a maximum peak of 5.7 GHz when cooling conditions good.
AMD thus indicates that single-core performance is increased by 13% on average at the same frequency and up to 44% in applications that take advantage of all cores. Enough to pass the 12th generation Intel Core chips, in games and in applications according to AMD – but this generation of Ryzen processors will finally go to war against the 13th generation Core, let’s keep this in mind. AMD thus provides an example of 3D rendering in raytracing, implemented 57% faster on a Ryzen 9 7950X than on a Core i9-12900K. In games too, AMD is confident, assuring that a “simple” Ryzen 5 7600X is faster than a Core i9-12900K, with an average advantage of 5% in a selection of games developed by AMD .
At launch, only four references will be offered for 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 noticed that the number of cores does not change compared to Ryzen 5000, which is not the case of power consumption. Thus, the Ryzen 9 7950X and 7900X are provided for a maximum of 170 watts, while the Ryzen 9 5950X is satisfied with 105 watts. It’s a funny situation, AMD doesn’t stop mocking the 12th generation Cores for their high power consumption. A unique choice in addition, this unclamping certainly makes it possible to reach a higher frequency, but at the cost of the need to use a very efficient cooling system – and therefore quite expensive.
However, AMD assures us, this series of processors offers higher energy efficiency than the competition, that is to say the 12th generation Intel Core chips. Thus, architectural changes and the use of 5 nm engraving allow the company to put forward more flattering figures such as the use of a chip that is approximately 50% smaller and offers approximately 47% higher energy efficiency. Other interesting data, the Ryzen 7000 will consume 62% less energy than the Ryzen 5000 at the same performance or 49% more performance at the same power consumption.
Regarding the AM5 platform – which will be used at least until 2025 – itself, the new socket has good taste to use the same repair system as the AM4 socket. This allows current cooling systems to be perfectly compatible with new motherboards. With AM5, AMD provides a design that can withstand a maximum load of 230 watts, thus leaving the manufacturer room for overclocking or possibly more power-hungry chips.
Currently, two chipsets are planned, each reduced to Extreme versions – a total of 4 chipset references therefore. The high-end motherboards will be based on using the X670 Extreme or X670 chips and the entry-level versions will draw on the B650 Exteme and B650 chips. Both chipsets result in the same performance, but the X changes give more latitude for overclocking. Regarding the difference between Extreme and classic versions, it is PCIe 5, which is limited to graphics card support in classic versions while it can combine graphics cards and SSDs in Extreme versions. The opportunity is also for AMD to announce that PCIe 5 SSDs are not expected until November.
In terms of memory, it will be exclusive support for DDR5. Although it is more expensive than DDR4, AMD expects to sell both technologies at the same price until the end of the second half of 2023. This support for DDR5 is accompanied by a new technology named AMD Expo that allows you to overclock the memory with one click through a specific application. A recent innovation that although not exclusive, Intel offers a similar functionality to the 12th generation Core.
As for pricing, only dollar prices have been announced to us – French prices will follow shortly. So it is necessary to calculate $299 for the 7600X, $399 for the 7700X, $549 for the 7900X and $699 for the 7950X. The prices are close to those charged for the Ryzen 5000 at their launch. The availability is scheduled for September 27 and there is no doubt that AMD will deliver more technical details of its new platform, its new features or even the overclocking capacity of its chips. In the process, Intel should provide more details on the 13th generation of Core processors. The start of the school year promises to be busy.
