Overview
SummaryThe Intel Xeon Gold 6238R is a server processor with 28 cores and 56 threads, built on the Cascade Lake architecture. It launched in Jan 2020. Clocks run from 2.2 GHz base to 4.0 GHz boost. A 38.5-MB L3 cache backs the cores (2.4 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 165 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).
Performance
12 metricsThe Intel Xeon Gold 6238R scores 2,168 in single-core performance and 34,751 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,680 for overall performance, 25,623 for productivity performance, 23,015 for creator performance, 46,479 for engineering performance and 15,192 for gaming performance. Its multi-core throughput works out to 1,241 per core, 621 per thread and 211 per watt. Its computed efficiency index is 676. Its performance index is 108, so its overall performance is 8% above 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.
