PostgreSQL benchmark with settings of Scaling Factor: 100, Clients: 800, Mode: Read Only. EPYC 8534P - 225W Power was the fastest.

Given the focus of AMD EPYC 8004 "Siena" processors for data center performance and efficiency, the first area of exploration was with various database workloads. Right off the bat with the very common PostgreSQL, the EPYC 8543P and EPYC 8534PN showed no troubles of competing with the Xeon Platinum 8468 comparable processor from the Sapphire Rapids line-up. At stock TDPs, the EPYC 8534P(N) performed similar to the Xeon Platinum 8468 but when running in the power determinism mode available from the BIOS is where the 64-core Siena CPUs shot out ahead of the Intel competition.

It was a similar story where it came to the latency metrics with PostgreSQL.

For as great and competitive as the PostgreSQL performance was with the EPYC 8534P(N) processors, when it came to the CPU power consumption is what made the results all the more impressive. The EPYC 8534P in power determinism mode was running 15% faster than the Xeon Platinum 8468 while doing so at 69% the power use!

Not only was the EPYC 8534P(N) more power efficient, but it was also much more cost effective than the Xeon Platinum 8468 when looking at the CPU + RAM pricing.

When ramping up PostgreSQL 16 with 1000 concurrent clients over 800 clients, the EPYC 8534P continued to offer similar performance out-of-the-box to the Xeon Platinum 8468 or a measurable lead operating in power determinism mode. All the while the Zen 4C cores with EPYC Siena were sipping on power in comparison to the Xeon Platinum Sapphire Rapids processor.

TiDB Community Server benchmark with settings of Test: oltp_read_write, Threads: 128. Xeon Platinum 8468 - 6c RAM was the fastest.

In the case of the TiDB database server from PingCAP, the Xeon Platinum 8468 did outperform the EPYC 8534P / 8534PN processors in raw performance, but when it came to the power consumption and in turn the efficiency it was a very different story:

The EPYC Siena processors were continuing to pull significantly less power than the Xeon Platinum processor and in turn these new AMD EPYC processors delivered a superb power efficiency advantage.

The EPYC 8534P was delivering the best value for TiDB of the processor / RAM combinations tested.
