Intel® Xeon™ Platinum 8273CL

The Intel Xeon Platinum 8273CL is a server processor with 28 cores and 56 threads. Clocks run from 2.2 GHz base to 3.7 GHz boost. A 38.5-MB L3 cache backs the cores (1.4 MB per core). It supports DDR4 memory. It uses the FCLGA3647 socket. Rated TDP is 165 W. Notable platform capabilities: AVX-512, Extended Page Tables (EPT).

The Intel Xeon Platinum 8273CL scores 2,200 in single-core performance and 37,320 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 9,061 for overall performance, 27,338 for productivity performance, 24,486 for creator performance, 49,916 for engineering performance and 15,930 for gaming performance. Its multi-core throughput works out to 1,333 per core, 666 per thread and 226 per watt. Its computed efficiency index is 705. Its performance index is 112, so its overall performance is 12% 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.

Workload sub-scores (integer math, floating point, compression, encryption, physics, SIMD, prime sieve and sorting) are not recorded for the Intel Xeon Platinum 8273CL.

The Intel Xeon Platinum 8273CL has 28 physical cores and runs 56 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 2.20 GHz and boosts up to 3.70 GHz.
