AMD® EPYC™ 9734

The AMD EPYC 9734 is a server processor with 112 cores and 224 threads, built on the Zen 4 architecture (5 nm process). It launched in Jun 2023. Clocks run from 2.2 GHz base to 3.0 GHz boost. A 256-MB L3 cache backs the cores (3.4 MB per core). It supports DDR5 memory. The chip drops into the SP5 socket and exposes PCIe 5.0 (128 lanes). Rated TDP is 340 W. Notable platform capabilities: AVX-512, AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 9734 scores 2,310 in single-core performance and 102,286 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 15,371 for overall performance, 69,720 for productivity performance, 60,415 for creator performance, 143,200 for engineering performance and 32,502 for gaming performance. Its multi-core throughput works out to 913 per core, 457 per thread and 301 per watt. Its computed efficiency index is 834. Its performance index is 190, so its overall performance is 90% 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 9734 scores 823,150 in integer math, 549,045 in floating-point math, 2,900,008 in compression, 179,390 in cryptography, 6,747 in physics simulation, 205,925 in vector SIMD, 829 in the prime sieve and 357,638 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 1,298% above in integer math, 1,096% above in floating-point math, 1,172% above in compression, 1,461% above in cryptography, 519% above in physics simulation, 1,228% above in vector SIMD, 1,137% above in the prime sieve and 1,479% 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 9734 has 112 physical cores and runs 224 logical threads. It runs 2 threads per core. It runs at a base clock of 2.20 GHz and boosts up to 3.00 GHz. Its clock multiplier is unlocked for overclocking.

The AMD EPYC 9734 is a server processor, belongs to the AMD EPYC family, uses the Zen 4 architecture, carries the codename Bergamo and is manufactured on a 5 nm process. It launched in Jun 2023.

The AMD EPYC 9734 has 7 MB of L1 cache, 112 MB of L2 cache and 256 MB of L3 cache. That adds up to about 375.0 MB of cache, or 3.35 MB per core. Each core has 1 MB of private L2 cache.

The AMD EPYC 9734 has a 3-level cache hierarchy: L1 at 7 MB, L2 at 112 MB and L3 at 256 MB. L3 is the largest level and makes up about 68% of the cache listed here.

The AMD EPYC 9734 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 9734 does not include integrated graphics, so a discrete graphics card is required for display output.

The AMD EPYC 9734 uses the SP5 socket, supports PCI Express 5.0 and provides up to 128 PCIe lanes.

The AMD EPYC 9734 has a rated TDP of 340 W.
