At the Supercomputing 2018 Conference, AMD announced a special high-frequency SKU in their first-generation 14nm AMD EPYC “Naples” line of server processors. This SKU will be the AMD EPYC 7371 processor. This upcoming processor will have 16C/32T, with a base clock speed of 3.1 GHz. It will boost up to 3.6 GHz on all 16 cores and up to 3.8 GHz on eight cores. It also has a 64MB L3 cache.
This is a significant clock speed increase over the existing AMD EPYC 7351 processor. The EPYC 7351 has a base clock speed of 2.4 GHz, with a max boost speed of 2.9 GHz. This is especially relevant for SQL Server 2017 usage. This is because SQL Server 2017 licensing is based on core counts, not clock speeds or actual performance.
Because of this, you want to get the most performance and capacity possible for each licensed CPU core. A base clock speed increase of 29.2% is going to be quite noticeable on a typical SQL Server instance.
I hope that mainstream vendors like Dell offer this SKU in their existing systems. For example, the Dell PowerEdge R7415 and R7425 would be great choices.
