Intel® Xeon™ Platinum 8347C

The Intel Xeon Platinum 8347C is a server processor with 36 cores and 72 threads. Clocks run from 2.1 GHz base to 3.5 GHz boost. A 54-MB L3 cache backs the cores (1.5 MB per core). It supports DDR4 memory. It uses the FCLGA4189 socket. Rated TDP is 210 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8347C scores 2,445 in single-core performance and 49,386 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,989 for overall performance, 35,524 for productivity performance, 31,563 for creator performance, 69,140 for engineering performance and 19,682 for gaming performance. Its multi-core throughput works out to 1,372 per core, 686 per thread and 235 per watt. Its computed efficiency index is 758. Its performance index is 136, so its overall performance is 36% 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 Platinum 8347C scores 235,261 in integer math, 129,334 in floating-point math, 813,570 in compression, 46,939 in cryptography, 2,293 in physics simulation, 43,509 in vector SIMD, 189 in the prime sieve and 90,262 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 299% above in integer math, 182% above in floating-point math, 257% above in compression, 309% above in cryptography, 110% above in physics simulation, 181% above in vector SIMD, 182% above in the prime sieve and 298% 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 Platinum 8347C has 36 physical cores and runs 72 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.10 GHz and boosts up to 3.50 GHz.
