The alleged benchmarks come from Anandtech forum member, igor_kavinski, who reportedly got the test results from someone who had access to an early engineering sample of the AMD Ryzen 9 9950X CPU. The user was running the chip on an AM5 motherboard with DDR5-8000 memory that was operating with CL34-45-40-42 timings.

The AMD Ryzen 9 9950X "100-000001277" CPU is the flagship offering with two Zen 5 CCDs and a single IOD. The CPU offers 16 cores, 32 threads, a base clock of 4.3 GHz, and a max boost clock of up to 5.7 GHz. It comes with 80 MB of cache (64 MB L3 + 16 MB L2) and has a TDP of 170W. Now in terms of clock speed, while the boost clock is identical to the Ryzen 9 7950X, the base clock is slightly dialed down by -200 MHz but we can expect a lot of efficiency coming out of this flagship product, especially in terms of multi-threaded performance.
