The AMD Ryzen 9 7900 is a powerhouse in the world of desktop processors. Part of the Raphael series, this processor boasts 12 cores with hyperthreading (SMT), allowing it to handle an impressive 24 threads simultaneously. Launched in early 2023, the Ryzen 9 7900 stands out as the fastest 12-core processor with a 65-watt TDP.
Performance
With a base clock of 3.7 GHz and the ability to reach up to 5.4 GHz on a single core in Turbo mode, the Ryzen 9 7900 offers a remarkable performance boost. The internal structure retains the chiplet design, featuring two CCD clusters, each housing a CCX with 8 cores. The manufacturing process has seen an upgrade to 5 nm, contributing to higher clock rates. Additionally, the IO die, responsible for the memory controller and iGPU, is now manufactured in a 6 nm structure width.
One notable improvement is the processor's ability to impress in gaming scenarios, thanks to the significantly enhanced IPC (Instructions Per Cycle).
