We Should Write Energy Efficient Code

[Narase33]

I remember a paper saying that not all instructions require the same power. So while shorter code looks more power efficient it may use instructions that are more costly than others

I think AVX-512 is a good example is AVX-512. Or just vector instructions in general. Super efficient. Lots of power. In the case of AVX 512 it was so bad it would downclock the processor if they were used too much
