AMD® EPYC™ 7662

The AMD EPYC 7662 is a server processor with 64 cores and 128 threads, built on the Zen 2 architecture. It launched in Aug 2019. Clocks run from 2.0 GHz base to 3.3 GHz boost. A 256-MB L3 cache backs the cores (4.6 MB per core). It supports DDR4 memory. The chip drops into the SP3 socket and exposes PCIe 4.0 (128 lanes). Rated TDP is 225 W. Notable platform capabilities: AMD-V (Hardware Virtualization), AMD SEV.

The AMD EPYC 7662 scores 2,102 in single-core performance and 72,298 in multi-core performance (PassMark CPU Mark ratings). From those two ratings Feex computes 12,328 for overall performance, 49,937 for productivity performance, 43,548 for creator performance, 101,217 for engineering performance and 24,381 for gaming performance. Its multi-core throughput works out to 1,130 per core, 565 per thread and 321 per watt. Its computed efficiency index is 822. Its performance index is 153, so its overall performance is 53% 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 7662 scores 396,692 in integer math, 229,270 in floating-point math, 1,473,281 in compression, 110,044 in cryptography, 6,710 in physics simulation, 80,798 in vector SIMD, 541 in the prime sieve and 175,277 in sorting. Higher is better. Compared with the Intel Core i5-12400, it is 574% above in integer math, 400% above in floating-point math, 546% above in compression, 858% above in cryptography, 516% above in physics simulation, 421% above in vector SIMD, 707% above in the prime sieve and 674% 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 7662 has 64 physical cores and runs 128 logical threads. It does not use a hybrid performance and efficiency core layout. It runs 2 threads per core. It runs at a base clock of 2.00 GHz and boosts up to 3.30 GHz.

The AMD EPYC 7662 is a server processor, belongs to the AMD EPYC family and uses the Zen 2 architecture. It launched in Aug 2019.

The AMD EPYC 7662 has 4 MB of L1 cache, 32 MB of L2 cache and 256 MB of L3 cache. That adds up to about 292.0 MB of cache, or 4.56 MB per core. Each core has 512 KB of private L2 cache.

The AMD EPYC 7662 has a 3-level cache hierarchy: L1 at 4 MB, L2 at 32 MB and L3 at 256 MB. L3 is the largest level and makes up about 88% of the cache listed here.

The AMD EPYC 7662 supports DDR4 memory, uses 8 memory channels, runs memory at up to 3,200 MT/s and delivers up to 204.8 GB/s of memory bandwidth. It does not support DDR5 and LPDDR memory.

The AMD EPYC 7662 uses the SP3 socket, supports PCI Express 4.0 and provides up to 128 PCIe lanes.

The AMD EPYC 7662 has a rated TDP of 225 W.
