AMD EPYC 7543 ‘Milan’ Server CPU With 32 Zen 3 Cores & 3.7 GHz Clocks Benchmarked, Huge Single-Threaded Performance Increase

The latest AMD EPYC 7543 'Milan' Server CPU benchmarks have leaked out and showcase a huge single-core performance jump. Benchmarks for the same CPU also leaked out a while ago and we saw the 32 chip delivering performance on par with dual Intel Xeon CPUs that featured 56 cores & 112 threads.

The benchmarks are once again from a 1P (single-socket) server running the AMD EPYC 7543 CPU which is part of the 3rd Gen Milan lineup. The Milan lineup is based on the Zen 3 architecture and features a new core/cache configuration. The Wiwynn SV302A-U is a 1U rack that comes equipped with a total of 384 GB of DDR4 memory.

The AMD EPYC 7543 CPU features the Zen 3 core architecture and is comprised of 32 cores and 64 threads. As for clock speeds, the chip has a rated base clock of 2.80 GHz and boosts up to 3.70 GHz which is quite a respectable clock rate for the processor. Based on the clocks, we can assume that this part will have a TDP close to 200W. The CPU also features 256 MB of L3 cache and 16 MB of L2 cache. It confirms that the chip is actually making use of 8 CCD's instead of four. The four CCD 32 core part would be configured for a different SKU with 128 MB of L3 cache.

Looking at the performance numbers, the AMD EPYC 7543 was able to score 1343 points in single-core and 25909 points in multi-core tests. Do note that the multi-core performance is a bit lacking versus the Intel Xeon parts we will be using for comparison but that's mostly due to the fact that the benchmark makes use of AVX-512 speedup which gives the Intel CPUs an advantage so we will be primarily focusing on the single-core performance.

Versus its predecessor, the EPYC 7542, AMD's EPYC 7543 scores a 37% lead in single-core and a 2x increase in multi-core tests. These numbers are taken from the average results for the EPYC 7542 within Geekbench 5 database. Moving to the Intel Xeon parts, the chip scores a 25-30% lead over the Xeon Gold 6246R (32 Core Dual) & Xeon 6254 (36 core Dual) in single-core tests. The CPU also manages a 20% lead over the Xeon Gold 6258R which boosts up to 4.0 GHz.

Intel Xeon Gold 6248 (3.9GHz)
Intel Xeon Gold 6246R (4.10 GHz)
AMD EPYC 7542 (3.4 GHz)

So in apples to apple comparison, the AMD EPYC Milan CPUs will have a tremendously higher lead and we are just taking general performance without mentioning the better performance/value and perf per watt which would translate to lower TCO when building a Milan server. AMD also showed benchmarks of its 32 Core Milan server CPU which was 68% faster than a comparable Xeon Gold platform in their recent CES 2021 keynote, you can read more about that here.
