Intel® Xeon™ E-2456

The Intel Xeon E-2456 is a server processor with 6 cores and 12 threads, built on the Raptor Lake architecture. It launched in Oct 2023. Clocks run from 3.3 GHz base to 5.1 GHz boost. A 18-MB L3 cache backs the cores (3.0 MB per core). It addresses DDR5 memory up to 128 GB across 2 channels. The chip drops into the FCLGA1700 socket and exposes PCIe 5.0 (20 lanes). Rated TDP is 80 W. Notable platform capabilities: Extended Page Tables (EPT).

The Intel Xeon E-2456 scores 3,568 in single-core performance and 20,808 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 8,616 for overall performance, 18,520 for productivity performance, 17,867 for creator performance, 20,678 for engineering performance and 15,906 for gaming performance. Its multi-core throughput works out to 3,468 per core, 1,734 per thread and 260 per watt. Its computed efficiency index is 963. Its performance index is 107, so its overall performance is 7% 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-2456 scores 64,992 in integer math, 49,646 in floating-point math, 230,096 in compression, 12,342 in cryptography, 1,600 in physics simulation, 15,176 in vector SIMD, 98 in the prime sieve and 24,822 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 10% above in integer math, 8% above in floating-point math, 1% above in compression, 7% above in cryptography, 47% above in physics simulation, 2% below in vector SIMD, 46% above in the prime sieve and 10% 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-2456 has 6 physical cores and runs 12 logical threads. It runs 2 threads per core. It runs at a base clock of 3.30 GHz and boosts up to 5.10 GHz.
