I can't remember where I read this, but there was an argument somewhere that worrying about downclocking only really makes sense when the instruction set in question is new. (Which AVX-512 certainly is, to be fair.) Eventually, when the instruction set is more widely used, you'll probably already be paying the downclocking penalty anyway because of someone else's code, and you might as well go ahead and use the fancy instructions in your own code. Do you think that's valid?
