AMD's biggest fight with stock is brand recognition. Everybody knows that amd stock coolers really suck. Why? Because most ppl had either Phenoms/Athlon or FX cpus, and the stock coolers were abysmal noise monsters compared to Intel stock, which were actually functional. Just so happens to be totally reversed position now, amd coolers are superb, bordering the same performance as a CM hyper212, yet Intel still hands out the barely adequate. But just like any fanboy is stuck with gusto to vote for his team, so have many decided that the red team just plain sucks and changing their minds is an uphill battle, both ways, through deep snow drifts on a really cold day in (that place). Stubborn.
Fact is, amd has always been a leader in innovation, everything from tri-core, quad-core, Hexa-core, octo-core, all amd. Intel took the safer route and increased performance in what was already there. And now amd ups the game again with stock coolers, some even led/RGB that are far superior to the cpus needs.
Amd may not be quite as good as Intel, on some stuff, but give'm a break, compared to Intel 'tick-tock', Ryzens 40% IPC increase is huge.
