https://www.techpowerup.com/322906/amd-ryzen-9000-zen-5-single-thread-performance-at-5-80-ghz-found-19-over-zen-4 An AMD Ryzen 9000 "Granite Ridge" desktop processor engineering sample with a maximum boost frequency of 5.80 GHz was found to offer an astonishing 19% higher single-threaded performance increase over an AMD Ryzen 9 7950X. "Granite Ridge" is codename for the Socket AM5 desktop processor family that implements the new "Zen 5" CPU microarchitecture. The unnamed "Granite Ridge" processor comes with an OPN code of 100-0000001290. Its CPU core count is irrelevant, as the single-threaded performance is in question here. The processor boosts up to 5.80 GHz, which means the core handling the single-threaded benchmark workload is achieving this speed. This speed is 100 MHz higher than the 5.70 GHz that the Ryzen 9 7950X processor based on the "Zen 4" architecture, boosts up to.
The single-threaded benchmark in question is the CPU-Z Bench. The mostly blurred out CPU-Z screenshot that reveals the OPN also mentions a processor TDP of 170 W, which means this engineering sample chip is either 12-core or 16-core. The chip posts a CPU-Z Bench single-thread score of 910 points, which matches that of the Intel Core i9-14900K with its 908 points. You've to understand that the i9-14900K boosts one of its P-cores to 6.00 GHz, to yield the 908 points that's part CPU-Z's reference scores. So straight off the bat, we see that "Zen 5" has a higher IPC than the "Raptor Cove" P-core powering the i9-14900K. Its gaming performance might end up higher than the Ryzen 7000 X3D family.
Not too bad for an engineering sample
