Intel® Xeon™ E-2388G

The Intel Xeon E-2388G is a server processor with 8 cores and 16 threads, built on the Rocket Lake architecture. It launched in Jul 2021. Clocks run from 3.2 GHz base to 5.1 GHz boost. A 16-MB L3 cache backs the cores (2.3 MB per core). It addresses DDR4 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1200 socket and exposes PCIe 4.0 (20 lanes). Rated TDP is 95 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon E-2388G scores 3,399 in single-core performance and 23,458 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,929 for overall performance, 20,006 for productivity performance, 19,020 for creator performance, 24,044 for engineering performance and 16,062 for gaming performance. Its multi-core throughput works out to 2,932 per core, 1,466 per thread and 247 per watt. Its computed efficiency index is 916. Its performance index is 111, so its overall performance is 11% 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 E-2388G scores 85,558 in integer math, 45,999 in floating-point math, 291,289 in compression, 16,880 in cryptography, 1,130 in physics simulation, 17,212 in vector SIMD, 72 in the prime sieve and 36,699 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 45% above in integer math, equal in floating-point math, 28% above in compression, 47% above in cryptography, 4% above in physics simulation, 11% above in vector SIMD, 7% above in the prime sieve and 62% 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 E-2388G has 8 physical cores and runs 16 logical threads. It runs 2 threads per core. It runs at a base clock of 3.20 GHz and boosts up to 5.10 GHz.
