Intel® Xeon™ Platinum 8158

The Intel Xeon Platinum 8158 is a server processor with 12 cores and 24 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 3.0 GHz base to 3.7 GHz boost. A 24.75-MB L3 cache backs the cores (3.1 MB per core). It addresses DDR4 memory up to 768 GB across 6 channels. The chip drops into the FCLGA3647 socket and exposes PCIe 3.0 (48 lanes). Rated TDP is 150 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8158 has 12 physical cores and runs 24 logical threads. It runs 2 threads per core. It runs at a base clock of 3.00 GHz and boosts up to 3.70 GHz.

The Intel Xeon Platinum 8158 is a server processor, belongs to the Intel Xeon Platinum family, uses the Skylake architecture, carries the codename Skylake and is manufactured on a 14 nm process. It launched in Jul 2017.

The Intel Xeon Platinum 8158 has 12 MB of L2 cache and 24.8 MB of L3 cache. That adds up to about 36.8 MB of cache, or 3.06 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8158 has a 2-level cache hierarchy: L2 at 12 MB and L3 at 24.8 MB. L3 is the largest level and makes up about 67% of the cache listed here.

The Intel Xeon Platinum 8158 supports DDR4 memory, addresses up to 768 GB of memory, uses 6 memory channels, runs memory at up to 2,666 MT/s and delivers up to 128.0 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Platinum 8158 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8158 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8158 has a rated TDP of 150 W.
