A Look At The GCC Compiler Tuning Performance Impact For Intel Ice Lake

For the SciMark2 micro-benchmarks, the skylake-avx512 microarchitecture optimizations performed the best on this Core i7 Ice Lake consumer laptop.

Some of the SciMark2 sub-tests like Monte Carlo did perform at their best with icelake-client.

The GraphicsMagick image manipulation benchmarks generally regressed with skylake-avx512/icelake-client tuning.

The Dav1d AV1 video decoder while relying upon hand-tuned x86_64 Assembly did see lower performance with the options past Skylake.

Intel's Scalable Video Technology encoders also saw a performance drop from those compiler tuning levels with AVX-512 on the Core i7-1065G7.
