Xeon Platinum 8256 is a 64-bit 4-core x86 high-performance server microprocessor introduced by Intel in early 2019. The Platinum 8256 is based on the Cascade Lake microarchitecture and is manufactured on a 14 nm process. This chip supports 8-way multiprocessing, sports 2 AVX-512 FMA units as well as three Ultra Path Interconnect links. This microprocessor supports up 1 TiB of hexa-channel DDR4-2933 memory, operates at 3.8 GHz with a TDP of 105 W and features a turbo boost frequency of up to 3.9 GHz.
