AMD Zen 5 Execution Engine Leaked, Features True 512-bit FPU AMD "Zen 5" CPU microarchitecture will introduce a significant performance increase for AVX-512 workloads, with some sources reported as high as 40% performance increases over "Zen 4" in benchmarks that use AVX-512. A leaked AMD slide detailing the execution engine of "Zen 5" holds the answer to how the company managed this—using a true 512-bit FPU. Currently, AMD uses a dual-pumped 256-bit FPU to execute AVX-512 workloads on "Zen 4." The updated FPU should significantly improve the core's performance in workloads that take advantage of 512-bit AVX or VNNI instructions, such as AI. https://www.techpowerup.com/321201/a...ue-512-bit-fpu |
