Intel® Xeon™ Platinum 8170

The Intel Xeon Platinum 8170 is a server processor with 26 cores and 52 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 2.1 GHz base to 3.7 GHz boost. A 35.75-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 8170 scores 2,162 in single-core performance and 27,957 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,775 for overall performance, 21,199 for productivity performance, 19,268 for creator performance, 36,519 for engineering performance and 13,475 for gaming performance. Its multi-core throughput works out to 1,075 per core, 538 per thread and 169 per watt. Its computed efficiency index is 605. Its performance index is 96, so its overall performance is 4% 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 8170 scores 134,566 in integer math, 71,568 in floating-point math, 554,062 in compression, 16,876 in cryptography, 749 in physics simulation, 34,360 in vector SIMD, 77 in the prime sieve and 43,229 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 128% above in integer math, 56% above in floating-point math, 143% above in compression, 47% above in cryptography, 31% below in physics simulation, 122% above in vector SIMD, 15% above in the prime sieve and 91% 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 8170 has 26 physical cores and runs 52 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.70 GHz.

The Intel Xeon Platinum 8170 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 8170 has 26 MB of L2 cache and 35.8 MB of L3 cache. That adds up to about 61.8 MB of cache, or 2.38 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Platinum 8170 has a 2-level cache hierarchy: L2 at 26 MB and L3 at 35.8 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon Platinum 8170 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 8170 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Platinum 8170 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Platinum 8170 has a rated TDP of 165 W.
