Intel® Xeon™ Platinum 8176

The Intel Xeon Platinum 8176 is a server processor with 28 cores and 56 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.1 GHz base to 3.8 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 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 165 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8176 scores 1,976 in single-core performance and 29,836 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,678 for overall performance, 22,160 for productivity performance, 19,967 for creator performance, 39,906 for engineering performance and 13,387 for gaming performance. Its multi-core throughput works out to 1,066 per core, 533 per thread and 181 per watt. Its computed efficiency index is 598. Its performance index is 95, so its overall performance is 5% below the Intel Core i5-12400 (index 100). Each bar shows the score as a share of a reference ceiling, which is the larger of the 99th-percentile score across the Feex CPU database and a fixed baseline.

Scores for individual PassMark CPU Mark test categories. Higher is better. These are measured test scores, not computed from the single-core and multi-core ratings.

In the individual workload tests the Intel Xeon Platinum 8176 scores 142,674 in integer math, 82,533 in floating-point math, 593,418 in compression, 15,167 in cryptography, 1,774 in physics simulation, 39,639 in vector SIMD, 147 in the prime sieve and 71,967 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 142% above in integer math, 80% above in floating-point math, 160% above in compression, 32% above in cryptography, 63% above in physics simulation, 156% above in vector SIMD, 119% above in the prime sieve and 218% above in sorting. Each bar shows the score as a share of that workload's reference ceiling, the larger of the 99th-percentile score across CPUs with a recorded value and a fixed baseline.

The Intel Xeon Platinum 8176 has 28 physical cores and runs 56 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.80 GHz.

The Intel Xeon Platinum 8176 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 8176 has 1 MB of L1 cache, 28 MB of L2 cache and 38.5 MB of L3 cache. That adds up to about 67.5 MB of cache, or 2.41 MB per core.

The Intel Xeon Platinum 8176 has a 3-level cache hierarchy: L1 at 1 MB, L2 at 28 MB and L3 at 38.5 MB. L3 is the largest level and makes up about 57% of the cache listed here.

The Intel Xeon Platinum 8176 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 8176 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8176 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8176 has a rated TDP of 165 W.
