AMD® EPYC™ 7303

The AMD EPYC 7303 is a server processor with 16 cores and 32 threads, built on the Zen 3 architecture. It launched in Sep 2023. Clocks run from 2.4 GHz base to 3.4 GHz boost. A 64-MB L3 cache backs the cores (4.6 MB per core). It supports DDR4 memory. Rated TDP is 130 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 7303 scores 1,460 in single-core performance and 28,572 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 6,459 for overall performance, 20,616 for productivity performance, 18,343 for creator performance, 32,858 for engineering performance and 11,523 for gaming performance. Its multi-core throughput works out to 1,786 per core, 893 per thread and 220 per watt. Its computed efficiency index is 567. Its performance index is 80, so its overall performance is 20% below 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 7303 scores 113,422 in integer math, 64,940 in floating-point math, 428,319 in compression, 25,167 in cryptography, 1,792 in physics simulation, 31,603 in vector SIMD, 180 in the prime sieve and 42,259 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 93% above in integer math, 41% above in floating-point math, 88% above in compression, 119% above in cryptography, 64% above in physics simulation, 104% above in vector SIMD, 169% above in the prime sieve and 87% 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 7303 has 16 physical cores and runs 32 logical threads. It runs 2 threads per core. It runs at a base clock of 2.40 GHz and boosts up to 3.40 GHz.

The AMD EPYC 7303 is a server processor, belongs to the AMD EPYC family and uses the Zen 3 architecture. It launched in Sep 2023.

The AMD EPYC 7303 has 1 MB of L1 cache, 8 MB of L2 cache and 64 MB of L3 cache. That adds up to about 73.0 MB of cache, or 4.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD EPYC 7303 has a 3-level cache hierarchy: L1 at 1 MB, L2 at 8 MB and L3 at 64 MB. L3 is the largest level and makes up about 88% of the cache listed here.

The AMD EPYC 7303 supports DDR4 memory and uses 8 memory channels. It does not support DDR5 and LPDDR memory.

The AMD EPYC 7303 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 7303 supports PCI Express 4.0.

The AMD EPYC 7303 has a rated TDP of 130 W.
