Intel® Xeon™ Gold 6238

The Intel Xeon Gold 6238 is a server processor with 22 cores and 44 threads, built on the Cascade Lake architecture. It launched in Apr 2019. Clocks run from 2.1 GHz base to 3.7 GHz boost. A 30.25-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 140 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6238 scores 1,978 in single-core performance and 29,057 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 7,581 for overall performance, 21,656 for productivity performance, 19,542 for creator performance, 36,140 for engineering performance and 13,198 for gaming performance. Its multi-core throughput works out to 1,321 per core, 660 per thread and 208 per watt. Its computed efficiency index is 641. Its performance index is 94, so its overall performance is 6% 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 Gold 6238 scores 111,160 in integer math, 68,709 in floating-point math, 486,644 in compression, 11,687 in cryptography, 1,871 in physics simulation, 36,746 in vector SIMD, 131 in the prime sieve and 60,553 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 89% above in integer math, 50% above in floating-point math, 113% above in compression, 2% above in cryptography, 72% above in physics simulation, 137% above in vector SIMD, 96% above in the prime sieve and 167% 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 Gold 6238 has 22 physical cores and runs 44 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 Gold 6238 is a server processor, belongs to the Intel Xeon Gold family, uses the Cascade Lake architecture, carries the codename Cascade Lake and is manufactured on a 14 nm process. It launched in Apr 2019.

The Intel Xeon Gold 6238 has 64 KB of L1 cache, 22 MB of L2 cache and 30.3 MB of L3 cache. That adds up to about 52.3 MB of cache, or 2.38 MB per core.

The Intel Xeon Gold 6238 has a 3-level cache hierarchy: L1 at 64 KB, L2 at 22 MB and L3 at 30.3 MB. L3 is the largest level and makes up about 58% of the cache listed here.

The Intel Xeon Gold 6238 supports DDR4 memory, addresses up to 1,024 GB of memory, uses 6 memory channels, runs memory at up to 2,933 MT/s and delivers up to 140.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Gold 6238 does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6238 uses the FCLGA3647 socket, supports PCI Express 3.0 and provides up to 48 PCIe lanes.

The Intel Xeon Gold 6238 has a rated TDP of 140 W.
