Son, you can find this shit on AMD brochure at the time. They went all in to advertise that "new way to do multithreading". They really through it would catch on, just like inter thought P4's idea of "just fucking single thread maximum megahurtz" would work.
Both companies had to reset and go back to basics after those stupid misadventures where they tried to reinvent their CPUs. And both succeeded.
And I have zero company loyalty. I've owned CPUs from both AMD and intel. I've owned GPUs from ATI/AMD and Nvidia. I literally do not give a fuck about which company is the one that makes the best thing. I just want to know which thing is best so I don't buy a P4, or a Bulldozer, or a geforce FX and end up with a shitty product.
Hell, I owned a slot A Athlon of all things. It was great, kicked the shit out of P3.
