Re: None of the above
"More to the point here, buying a processor module without performing a minimal evaluation of how it works, and in particular whether its performance is suitable for its intended purpose, is not due diligence."
Buying processors involves careful evaluation, I come back to the processor market every 2 to 3 years and I have to re-educate myself each time to understand the technology of the day and it's pros and cons.
The terminology varies over this time period, with terms changing their meaning. Additionally AMD and Intel call similar features by different names simultaneously. It's always like comparing apples to oranges.
The key factor is never the marketing guff, it's the real world experience of running your particular workload.
If you know enough to understand what "cores" means then you know enough to understand that implementations vary even sticking with the same manufacturer from generation to generation. And if you don't dig into the specifics and their significance to you then you're one core short of a full die, and probably sharing a FP unit too.
