AMD Details Ryzen 7000 Launch: Ryzen 7950X and More, Coming Sept. 27th [anandtech.com]
Driving AMD's gains in this newest generation of desktop CPUs is a combination of architectural improvements underpinning the Zen 4 architecture, as well as moving production of the CPU core chiplets to TSMC's leading-edge 5nm process. The combination of which will allow AMD to deliver what they are saying is now a 13% increase in IPC over their Zen 3 architecture – up from an 11% claim as of Computex – as well as a sizable increase in CPU clockspeeds. The top-end Ryzen 9 7950X will have a maximum turbo clockspeed of 5.7GHz, 800MHz (16%) higher than the equivalent Ryzen 9 5950X. As a result, AMD expects to deliver a 29% generational increase in single-threaded performance, and even more in multi-threaded workloads.
Launching in conjunction with the new Ryzen 7000 series chips will be AMD's AM5 platform, which will be cornerstone of AMD's consumer desktop platform through at least 2025. AM5 introduces DDR5 and PCIe 5.0 support for AMD's chips, as well as a new LGA socket. 4 chipsets are planned thus far – X670 Extreme, X670, B660 Extreme, and B660 – with X670 series boards available for the September launch, and B660 series boards set to follow in October.

While top TDPs have increased to 170W (230W socket power delivery) for the 7950X and 7900X, power efficiency is up. Mark Papermaster called the 65W TDP a "sweet spot" for TSMC's N5 node, claiming that the 7950X is 74% faster than the 5950X when limited to 65W.
AVX-512 instruction set support has been added. Huge frequency drops seen on previous Intel implementations may be avoided due to the design. Up to 150% performance increase over Ryzen 5000 (INT8 VNNI).
PCIe 5.0 SSDs will become available in November 2022. Socket AM5 is planned to last through at least 2025, with Zen 5 CPUs arriving sometime in 2024.
No new details were given about the RDNA2 iGPU that will be found in Ryzen 7000 desktop CPUs, but the current expectation is 2 compute units (compare to 6-12 CUs in Rembrandt APUs).
