AMD has revealed the new architecture with Zen4 desktop CPUs, codenamed "Raphael". All four new CPUs will be available from September 27th.
AMD today unveiled its 5 nm Ryzen 7000 lineup, detailing four new models ranging from the top-of-the-line $699 16 core Ryzen 9 7950X, which AMD claims is the world's fastest CPU, to the $299 six-core Ryzen 5 7600X, the current entry-level processor among Zen 4 processors.
Ryzen 7000 chips have a maximum of 16 cores. So, across the AMD product range, the number of cores is the same in this generation as in the previous one. AMD's flagship SKU will offer 16 cores, followed by 12, 8, and finally 6 CPU cores. As before, AMD builds its own chips using up to two chiplets of Zen 4 CPU cores (CCDs), each of which includes 8 Zen 4 CPU cores.
|MSRP||Core / Thread||Base / Boost Clock||Cache (L2+L3)||TDP||Memory|
|Ryzen 9 7950X||$699||16 / 32||4.5 / 5.7 GHz||80 MB||170 W||DDR5-5200|
|Ryzen 9 7900X||$549||12 / 24||4.7 / 5.6 GHz||76 MB||170 W||DDR5-5200|
|Ryzen 7 7700X||$399||8 / 16||4.5 / 5.4 GHz||40 MB||105 W||DDR5-5200|
|Ryzen 5 7600X||$299||6 / 12||4.7 / 5.3 GHz||38 MB||105 W||DDR5-5200|
Performance compared to the current generation
The Ryzen 7000 series will have an increase in IPC of about 13% compared to its predecessors and up to 29% higher single-threaded performance. This is mainly due to the higher clock speeds, which now reach 5.7 GHz on the flagship model, with an increase of 800 MHz compared to the current generation.
In the head-to-head with Intel's chips, AMD claims that the 7950X is overall 11% faster in games than Intel's fastest processor, the 12900K, and that the low-end Ryzen 5 7600X also beats the 12900K by about 5% in games.
New socket and chipsets
The new AM5 socket is based on a Lane Grid Array (LGA) socket with 1718 pins, called LGA1718. Among the significant advantages of the AM5 is the native support of PCIe 5.0 by the CPU, not only for the use of PCIe slots, but also for PCIe 5.0 storage, for which it is expected that the first consumer drives will begin to be sold around November 2022.
AMD also announced four chipsets for the Ryzen 7000:
The B650E chipset will complement the already well-known B650 chipset, but because it's part of AMD's “Extreme” chipset series, it will benefit from PCIe 5.0 lanes for at least one M.2 slot, as well as optional PCIe 5.0 support for a PCIe graphics slot, features not available with standard B650 cards.
This means AMD will have a mainstream platform with PCIe 5.0 by default (B650E) and a low-cost alternative with only PCIe 4.0 lanes for PEG and M.2 slots.
Support for this new platform is expected to last at least until 2025.
