But it does make sense in the context of real-world code optimization/execution.
Do you really hear from me for the first time that most non-SIMD code can't utilize a modern CPU in the way that SIMD code can ?
The only way to reach TDP limits of a modern CPU is from optimized SIMD code.
There are other limits to reach before power limits for non-AVX code.
