AMD® EPYC™ 9634

The AMD EPYC 9634 is a server processor with 84 cores and 168 threads, built on the Zen 4 architecture (5nm process). It launched in Nov 2022. Clocks run from 2.25 GHz base to 3.7 GHz boost. A 384-MB L3 cache backs the cores (5.6 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0 (128 lanes). Rated TDP is 290 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9634 scores 2,924 in single-core performance and 107,944 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 17,766 for overall performance, 74,257 for productivity performance, 64,632 for creator performance, 151,122 for engineering performance and 35,758 for gaming performance. Its multi-core throughput works out to 1,285 per core, 643 per thread and 372 per watt. Its computed efficiency index is 1,043. Its performance index is 220, so its overall performance is 120% 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 9634 scores 725,356 in integer math, 353,784 in floating-point math, 2,236,412 in compression, 151,943 in cryptography, 12,291 in physics simulation, 137,543 in vector SIMD, 1,176 in the prime sieve and 261,134 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 1,132% above in integer math, 671% above in floating-point math, 881% above in compression, 1,223% above in cryptography, 1,028% above in physics simulation, 787% above in vector SIMD, 1,655% above in the prime sieve and 1,053% 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 9634 has 84 physical cores and runs 168 logical threads. It runs 2 threads per core. It runs at a base clock of 2.25 GHz and boosts up to 3.70 GHz.

The AMD EPYC 9634 is a server processor, belongs to the AMD EPYC family, uses the Zen 4 architecture, carries the codename Genoa and is manufactured on a 5nm process. It launched in Nov 2022.

The AMD EPYC 9634 has 5.25 MB of L1 cache, 84 MB of L2 cache and 384 MB of L3 cache. That adds up to about 473.3 MB of cache, or 5.63 MB per core. Each core has 1 MB of private L2 cache.

The AMD EPYC 9634 has a 3-level cache hierarchy: L1 at 5.3 MB, L2 at 84 MB and L3 at 384 MB. L3 is the largest level and makes up about 81% of the cache listed here.

The AMD EPYC 9634 supports DDR5 memory, uses 12 memory channels, runs memory at up to 4,800 MT/s and delivers up to 460.8 GB/s of memory bandwidth. It does not support DDR4 and LPDDR memory.

The AMD EPYC 9634 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9634 uses the SP5 socket, supports PCI Express 5.0 and provides up to 128 PCIe lanes.

The AMD EPYC 9634 has a rated TDP of 290 W.
