Intel accused of inflating CPU benchmark results
SPEC says Intel's Xeon processors were using a compiler that artificially inflated the results of its industrial benchmark by as much as 9%.
In layman’s terms, SPEC is accusing Intel of optimizing the compiler specifically for its benchmark, which means the results weren’t indicative of how end users could expect to see performance in the real world. Slightly newer versions of the compilers used in the latest industrial Xeon processors, the 5th-gen Emerald Rapids series, do not use these allegedly performance-enhancing APIs. I’ll point out that both the Xeon processors and the SPEC 2017 test are some high-level hardware meant for “big iron” industrial and educational applications, and aren’t especially relevant for the consumer market we typically cover.
