Intel® Xeon™ Gold 6418H

The Intel Xeon Gold 6418H is a server processor with 24 cores and 48 threads, built on the Sapphire Rapids architecture. It launched in Jan 2023. Clocks run from 2.1 GHz base to 4.0 GHz boost. A 60-MB L3 cache backs the cores (2.5 MB per core). It addresses DDR5 memory up to 4 GB across 8 channels. The chip drops into the FCLGA4677 socket and exposes PCIe 5.0 (80 lanes). Rated TDP is 185 W. Notable platform capabilities: AMX (Advanced Matrix Extensions), AMX, AVX-512, Extended Page Tables (EPT).

The Intel Xeon Gold 6418H scores 2,741 in single-core performance and 51,711 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 11,905 for overall performance, 37,450 for productivity performance, 33,375 for creator performance, 65,932 for engineering performance and 21,151 for gaming performance. Its multi-core throughput works out to 2,155 per core, 1,077 per thread and 280 per watt. Its computed efficiency index is 875. Its performance index is 148, so its overall performance is 48% 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 6418H scores 180,810 in integer math, 141,053 in floating-point math, 708,539 in compression, 35,417 in cryptography, 5,250 in physics simulation, 55,195 in vector SIMD, 350 in the prime sieve and 77,661 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 207% above in integer math, 207% above in floating-point math, 211% above in compression, 208% above in cryptography, 382% above in physics simulation, 256% above in vector SIMD, 422% 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 6418H has 24 physical cores and runs 48 logical threads. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 4.00 GHz.

The Intel Xeon Gold 6418H is a server processor, belongs to the Intel Xeon Gold family, uses the Sapphire Rapids architecture and carries the codename Sapphire Rapids. It launched in Jan 2023.

The Intel Xeon Gold 6418H has 60 MB of L3 cache. That adds up to about 60.0 MB of cache, or 2.50 MB per core. Feex has no recorded L1 cache size for this processor.

The Intel Xeon Gold 6418H supports DDR5 memory, addresses up to 4 GB of memory and uses 8 memory channels. It does not support DDR4 and LPDDR memory.

The Intel Xeon Gold 6418H does not include integrated graphics, so a discrete graphics card is required for display output.

The Intel Xeon Gold 6418H uses the FCLGA4677 socket, supports PCI Express 5.0 and provides up to 80 PCIe lanes.

The Intel Xeon Gold 6418H has a rated TDP of 185 W.
