Overview
SummaryThe Intel Xeon Silver 4108 is a server processor with 8 cores and 16 threads, built on the Skylake architecture. It launched in Jul 2017. Clocks run from 1.8 GHz base to 3.0 GHz boost. A 11-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 85 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).
Performance
12 metricsThe Intel Xeon Silver 4108 scores 1,549 in single-core performance and 9,225 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 3,780 for overall performance, 8,165 for productivity performance, 7,862 for creator performance, 9,456 for engineering performance and 6,953 for gaming performance. Its multi-core throughput works out to 1,153 per core, 577 per thread and 109 per watt. Its computed efficiency index is 410. Its performance index is 47, so its overall performance is 53% 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
