AMD EPYC 9755
The AMD EPYC™ 9755 stands as the pinnacle of the standard performance line. Unlike the “dense” models, this processor uses full-fat Zen 5 cores, packing 128 Cores and a massive 512MB L3 Cache into the socket. It is designed for the most demanding enterprise workloads, including in-memory databases, heavy simulation (CFD), and AI model training. With a boost clock of 4.1 GHz and support for AVX-512, the 9755 delivers “no-compromise” performance, offering the core count of a dense chip with the per-core speed and cache depth of a performance chip.
