The Ryzen 9 9950X is AMD’s next flagship processor, boasting 16 cores and 32 threads, with a combined 80MB of L2+L3 cache and a boost clock speed of 5.7GHz. During the Ryzen 9000 launch at Computex, AMD claimed a 16% increase in instructions per cycle (IPC) performance, which is mostly due to the new Zen 5 architecture built on a 4nm node. The company had also claimed up to 56% performance gains in Blender compared to Intel’s Core i9-14900K and a 21% improvement in Cinebench 2024.

While these alleged performance gains are promising, it is important to note that the new Ryzen 9000 series CPUs will not surpass the gaming performance of the previous generation’s Ryzen 7000X3D models. AMD’s senior technical marketing manager confirmed this information in an interview that while these new chips will come close, they won’t match the gaming performance of their predecessors equipped with 3D V-Cache. In short, if you are aiming to buy the fastest gaming CPU, you might as well go for the Ryzen 9 7950X3D.

It is expected that preorders for AMD’s Ryzen 9000 chips will begin at 9 a.m. ET on July 31 with pricing starting around $315 for the Ryzen 5 9600X, going up to $610 for the Ryzen 9 9950X.
