The terminology isn't great, but I think it's at least better than the marketing terms for the levels which use something like "non-AVX turbo", "AVX2 turbo" and "AVX-512 turbo" for L0,1,2 respectively. This is really confusing because most AVX code will actually run in the faster non-AVX turbo and similarly for AVX-512 as described. So the marketing names are actually too pessimistic.
