Intel® Xeon™ Gold 6338N

The Intel Xeon Gold 6338N is a server processor with 32 cores and 64 threads, built on the Ice Lake architecture. It launched in Apr 2021. Clocks run from 2.2 GHz base to 3.5 GHz boost. A 48-MB L3 cache backs the cores (2.8 MB per core). It addresses DDR4 memory up to 6 GB across 8 channels. The chip drops into the FCLGA4189 socket and exposes PCIe 4.0 (64 lanes). Rated TDP is 185 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6338N scores 2,066 in single-core performance and 42,086 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,325 for overall performance, 30,248 for productivity performance, 26,866 for creator performance, 58,920 for engineering performance and 16,720 for gaming performance. Its multi-core throughput works out to 1,315 per core, 658 per thread and 228 per watt. Its computed efficiency index is 686. Its performance index is 116, so its overall performance is 16% 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.

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 6338N scores 177,468 in integer math, 103,931 in floating-point math, 642,024 in compression, 33,510 in cryptography, 2,864 in physics simulation, 47,612 in vector SIMD, 208 in the prime sieve and 77,628 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 201% above in integer math, 126% above in floating-point math, 182% above in compression, 192% above in cryptography, 163% above in physics simulation, 207% above in vector SIMD, 210% above in the prime sieve and 243% 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 6338N has 32 physical cores and runs 64 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.50 GHz.

The Intel Xeon Gold 6338N is a server processor, belongs to the Intel Xeon Gold family, uses the Ice Lake architecture, carries the codename Ice Lake and is manufactured on a 10 nm process. It launched in Apr 2021.

The Intel Xeon Gold 6338N has 40 MB of L2 cache and 48 MB of L3 cache. That adds up to about 88.0 MB of cache, or 2.75 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Gold 6338N has a 2-level cache hierarchy: L2 at 40 MB and L3 at 48 MB. L3 is the largest level and makes up about 55% of the cache listed here.

The Intel Xeon Gold 6338N supports DDR4 memory, addresses up to 6 GB of memory, uses 8 memory channels, runs memory at up to 2,666 MT/s and delivers up to 170.6 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The Intel Xeon Gold 6338N does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6338N uses the FCLGA4189 socket, supports PCI Express 4.0 and provides up to 64 PCIe lanes.

The Intel Xeon Gold 6338N has a rated TDP of 185 W.
