I'm sure this delivered large performance improvements and I wouldn't try arguing against it. Only in extreme circumstances does the cost (in processor time and I-cache footprint) translate to a tangible benefit - circumstances which usually resort to hand-coded assembly anyway.

Back in 2016, I gave a talk outlining the causes and effects of the terrible performance of web apps built using popular tools on the fastest-growing device segment: low-end to mid-range Android phones. Poor performance has a compound effect on user expectations at an ecosystem level. Live by the link, die by the link.

The L3 cache size is 64MB. The AMD EPYC 7551 processor has slightly lower single-threaded CPU performance when compared to the older 2.3 I wrote about using CPU-Z to benchmark the Intel Xeon E5-2673 v3 processor in an Azure VM in this article. Figure 1: CPU-Z Benchmark Results for LS16v2. The L3 cache size is 64MB.

Classics of the genre include: Apple's just focused on performance! The Performance Argument. As an engineer on a browser team, I'm privy to the blow-by-blow of various performance projects, benchmark fire drills, and the ways performance marketing (deeply) impacts engineering priorities. This is as it should be.

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.
