Last week for the AMD EPYC 4th Gen "Genoa" launch day I published initial AMD EPYC 9554 and EPYC 9654 Linux benchmarks as part of my review. Those 64-core and 96-core Zen 4 processors performed phenomenally with Genoa having AVX-512, twelve channels of DDR5-4800 system memory support, higher TDP allowance, and other improvements over prior Milan(X) server processors. The other SKU that AMD sent over for review is the EPYC 9374F as their new 32-core high frequency part. For less than $5k, the EPYC 9374F is a high frequency Zen 4 32-core part with a 320 Watt TDP. Today's benchmarks are looking at the EPYC 9374F against the EPYC 9554/9654 and various other AMD EPYC and Intel Xeon Scalable processors under Linux.

The EPYC 9374F features 32 cores / 64 threads, boasts a 256MB L3 cache, runs at a 3.85GHz base frequency and 4.3GHz boost frequency. For hitting these high frequencies on 32 cores, the EPYC 9374F has a default TDP of 320 Watts and a configurable TDP from 320 to 400 Watts. The 3.85GHz base frequency is the second highest in the EPYC Genoa line-up only to the EPYC 9274F 24-core processor that is a 320 Watt CPU with a 4.05GHz base frequency while having a 4.3GHz maximum boost frequency just like the larger 9374F. The EPYC 9374F has a suggested price of $4850 USD.

In comparison, the prior generation EPYC 75F3 was their 32-core high frequency part for Milan. The EPYC 75F3 had a 2.95GHz base clock and 4.0GHz maximum boost clock while having a 280 Watt TDP. With the EPYC 9374F, generationally that is a 30% increase to the base clock and 7.5% higher on the boost clock while the default TDP is 14% higher. The 1KU pricing at launch for the EPYC 75F3 was $4860, so basically the same price as the new EPYC 9374F. Buying the EPYC 75F3 new right now can be found for $5195 USD or even up around $5600 from some Internet retailers.

In addition to the EPYC 9274F and 9374F, there is also the EPYC 9174F as a high frequency 16-core part and then the EPYC 9474F as the 48-core high frequency part -- a 3.6GHz base frequency and 4.1GHz boost frequency there for that 360 Watt TDP processor. These Genoa "F" processors have the same Zen 4 architectural features in common with the rest of the EPYC 9004 series line-up including twelve channels of DDR5-4800 memory, PCIe 5.0, CXL 1.1+, and the other Genoa features covered last week.

Similar to last week's EPYC 9554/9654 Linux review, the EPYC 9374F was benchmarked in both 1P and 2P configurations. In both configurations also tested in the default "performance" determinism mode and then opting from the BIOS for the "power" determinism mode too.

While Ubuntu 22.04 LTS works great for the Genoa processors and AMD Titanite reference server platform, for all of this launch benchmarking I have been using Ubuntu 22.10 with the Linux 6.0 kernel for providing a very fresh and up-to-date look at the Linux performance, including with the use of the GCC 12 system compiler rather than GCC 11 as the default on 22.04 LTS, etc.
