SQL Performance

JULY 16, 2019

For many years, I explicitly advised people not to run their SQL Server workloads on AMD hardware because of the much lower single-threaded CPU performance and consequently higher SQL Server core license costs. This has led to a very noticeable reduction in generational performance increases since Broadwell-EP, as shown in Figure 1.
