Overview
SummaryThe AMD EPYC 8434P is a server processor with 48 cores and 96 threads, built on the Zen 4 architecture (5 nm process). It launched in Sep 2023. Clocks run from 2.5 GHz base to 3.1 GHz boost. A 128-MB L3 cache backs the cores (2.7 MB per core). It supports DDR5 memory. The chip drops into the SP6 socket and exposes PCIe 5.0 (96 lanes). Rated TDP is 200 W.
Performance
12 metricsThe AMD EPYC 8434P scores 2,448 in single-core performance and 66,490 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,758 for overall performance, 46,646 for productivity performance, 40,976 for creator performance, 93,086 for engineering performance and 23,967 for gaming performance. Its multi-core throughput works out to 1,385 per core, 693 per thread and 332 per watt. Its computed efficiency index is 902. Its performance index is 158, so its overall performance is 58% 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 8434P scores 385,290 in integer math, 215,669 in floating-point math, 1,412,835 in compression, 97,254 in cryptography, 4,036 in physics simulation, 86,189 in vector SIMD, 298 in the prime sieve and 125,932 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 554% above in integer math, 370% above in floating-point math, 520% above in compression, 746% above in cryptography, 270% above in physics simulation, 456% above in vector SIMD, 345% above in the prime sieve and 456% 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.
