Overview
SummaryThe AMD EPYC 7343 is a server processor with 16 cores and 32 threads, built on the Zen 3 architecture. It launched in Mar 2021. Clocks run from 3.2 GHz base to 3.9 GHz boost. A 128-MB L3 cache backs the cores (8.6 MB per core). It supports DDR4 memory. The chip drops into the SP3 socket and exposes PCIe 4.0 (128 lanes). Rated TDP is 190 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.
Performance
12 metricsThe AMD EPYC 7343 scores 2,752 in single-core performance and 43,778 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 10,976 for overall performance, 32,309 for productivity performance, 29,032 for creator performance, 50,345 for engineering performance and 19,201 for gaming performance. Its multi-core throughput works out to 2,736 per core, 1,368 per thread and 230 per watt. Its computed efficiency index is 796. 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.
How these scores are computed
Single-core and multi-core performance are PassMark CPU Mark single-thread and multi-thread ratings. Every other figure on this page's performance section is computed by Feex from those two ratings plus core count, thread count and TDP, so it is a derived value and not a separate benchmark run.
- Overall performance is the geometric mean of the two ratings: the square root of single-core times multi-core.
- Productivity performance is 0.65 times multi-core plus 1.4 times single-core.
- Creator performance is 0.55 times multi-core plus 1.8 times single-core.
- Engineering performance is multi-core times the smaller of 1.4 and (0.9 plus cores divided by 64).
- Gaming performance is 3 times single-core plus 0.25 times multi-core.
- Performance per core, per thread and per watt divide the multi-core rating by physical cores, logical threads and TDP in watts.
- The efficiency index is the square root of single-core times multi-core, divided by the square root of TDP.
- The performance index is overall performance divided by the overall performance of the Intel Core i5-12400 (8,069), times 100.
Workload Benchmarks
8 workloadsScores 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 7343 scores 156,089 in integer math, 86,396 in floating-point math, 589,078 in compression, 37,698 in cryptography, 4,823 in physics simulation, 35,218 in vector SIMD, 378 in the prime sieve and 68,751 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 165% above in integer math, 88% above in floating-point math, 158% above in compression, 228% above in cryptography, 342% above in physics simulation, 127% above in vector SIMD, 464% above in the prime sieve and 204% 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.
