Re: For procurement...
Err no to your first statement, kind of ok with the rest.
In some very precise benchmarks they have 30%. and precisely in those benchmarks the loss is about 17-18% (my own testing, but there are many more in the web).
It is in databases etc that intel shines.. and with Platinum processors at 10.000$ a pop.
i would say that for mainstream server processors AMD makes more sense right now.. who knows in the future. If you use AVX-512 a lot then of course not, but then you are not using it for mainstream uses...
