AMD® EPYC™ 7773X

The AMD EPYC 7773X is a server processor with 64 cores and 128 threads, built on the Zen 3 architecture. It launched in Mar 2021. Clocks run from 2.2 GHz base to 3.5 GHz boost. A 768-MB L3 cache backs the cores (12.6 MB per core). It supports DDR4 memory. The chip drops into the SP3 socket and exposes PCIe 4.0 (128 lanes). Rated TDP is 280 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 7773X scores 2,531 in single-core performance and 90,279 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,116 for overall performance, 62,225 for productivity performance, 54,209 for creator performance, 126,391 for engineering performance and 30,163 for gaming performance. Its multi-core throughput works out to 1,411 per core, 705 per thread and 322 per watt. Its computed efficiency index is 903. Its performance index is 187, so its overall performance is 87% 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 AMD EPYC 7773X scores 527,534 in integer math, 296,559 in floating-point math, 1,718,301 in compression, 126,823 in cryptography, 15,721 in physics simulation, 95,714 in vector SIMD, 1,201 in the prime sieve and 206,407 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 796% above in integer math, 546% above in floating-point math, 653% above in compression, 1,004% above in cryptography, 1,342% above in physics simulation, 517% above in vector SIMD, 1,693% above in the prime sieve and 811% 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 AMD EPYC 7773X has 64 physical cores and runs 128 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.50 GHz.

The AMD EPYC 7773X is a server processor, belongs to the AMD EPYC family and uses the Zen 3 architecture. It launched in Mar 2021.

The AMD EPYC 7773X has 4 MB of L1 cache, 32 MB of L2 cache and 768 MB of L3 cache. That adds up to about 804.0 MB of cache, or 12.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD EPYC 7773X has a 3-level cache hierarchy: L1 at 4 MB, L2 at 32 MB and L3 at 768 MB. L3 is the largest level and makes up about 96% of the cache listed here.

The AMD EPYC 7773X supports DDR4 memory, uses 8 memory channels, runs memory at up to 3,200 MT/s and delivers up to 204.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD EPYC 7773X does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 7773X uses the SP3 socket, supports PCI Express 4.0 and provides up to 128 PCIe lanes.

The AMD EPYC 7773X has a rated TDP of 280 W.
