AMD’s Ryzen 9 7950X, the flagship Zen 4 CPU, is going to offer an insanely high clock speed of up to 5.85GHz, an increase of nearly 1GHz over the Zen 3 5950X.
AMD Ryzen 9 7950X is going to be a beast with clock speeds, Zen 4 “Persephone” cores can clock up to 5.85GHz
The latest details for AMD’s flagship Ryzen 9 7950X CPU come from “Venom Warlock Marvin” at Weibo (via HXL). The user seems to be holding a retail monster that he says isn’t even top-tier, but he claims the chip can hit an absolutely phenomenal maximum clock speed of 5.85GHz. Angstronomics was the first to point this out, as the “F-Max” clocks back a while, which we’ve covered here. With PBO & XFR enabled, the chip can reach an even higher clock speed.
In addition, the leaker reports on the code names for the CCDs and cores of the AMD Ryzen 7000 CPU. The Raphael “Ryzen 7000” CPUs will contain up to two “Durango” CCDs, and each CCD will have a total of 8 “Persephone” Zen 4 cores. A block diagram shows that each CCD has a 32 MB cache (L3) pool and a GMI3 interface on each CCD connects it to the IOD (IO Die) which will use a 6nm process node.

AMD Ryzen 9 7950X 16 Core “Zen 4” Desktop CPU
Starting with the flagship of them all, we have the AMD Ryzen 9 7950X which retains its healthy 16-core and 32-thread count of the previous two generations. The CPU has an impressive base frequency of 4.5 GHz and a boost clock of up to 5.7 GHz, which should make it 200 MHz faster than Intel’s Alder Lake Core i9-12900KS with a boost frequency of 5.5 GHz on a single-core.
It seems AMD is extracting every ounce of Hertz it could within that 170W TDP (230W PPT) for the Ryzen 9 chips. As for the cache, the CPU comes with 80 MB of which 64 MB from L3 (32 MB per CCD) and 16 MB from L2 (1 MB per core).
The AMD Ryzen 7 7700X “Zen 4” CPU will launch next month along with the rest of the lineup. AMD also plans to make a full disclosure tomorrow.
