No argument.
But I'm a developer on Linux who uses a couple of languages that compile to machine code. Which means that I don't care if AMD has something twice as fast, I'm going to buy Intel for one reason alone: their performance counters support running rr.
That's at least a factor of two improvement in my productivity right there.
Last I heard, Ryzen's perfcounters weren't deterministic enough for rr, so it's dead to me.

For others who aren't as knowledgeable, could you give a quick rundown of rr and what causes this massive AMD penelty? I've never heard of anything that is "switch to Intel for double the performance".
