Intel® Xeon™ Platinum 8256

The Intel Xeon Platinum 8256 is a server processor with 4 cores and 8 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 3.8 GHz base to 3.9 GHz boost. A 16.5-MB L3 cache backs the cores (5.1 MB per core). It addresses DDR4 memory up to 1024 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 105 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8256 has 4 physical cores and runs 8 logical threads. It runs 2 threads per core. It runs at a base clock of 3.80 GHz and boosts up to 3.90 GHz.

The Intel Xeon Platinum 8256 is a server processor, belongs to the Intel Xeon Platinum family, uses the Cascade Lake architecture, carries the codename Cascade Lake and is manufactured on a 14 nm process. It launched in Apr 2019.

The Intel Xeon Platinum 8256 has 4 MB of L2 cache and 16.5 MB of L3 cache. That adds up to about 20.5 MB of cache, or 5.13 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8256 has a 2-level cache hierarchy: L2 at 4 MB and L3 at 16.5 MB. L3 is the largest level and makes up about 80% of the cache listed here.

The Intel Xeon Platinum 8256 supports DDR4 memory, addresses up to 1,024 GB of memory, uses 6 memory channels, runs memory at up to 2,933 MT/s and delivers up to 140.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Platinum 8256 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8256 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8256 has a rated TDP of 105 W.
