i doubt that even spending 100B on ads would bump amd sales even by a bit.
Says a lot of about your products if in this marketing and brand concious era you can't get folks to buy your products after telling them how great and even "magical" they are.
Remember you can sell any old crap if you hype it enough. Apple havent done too bad with this approach. Nice looking products but decidely average internally and price them high. But it doesnt matter cos we'll sell them as the 'cool' thing to have.
I just dont think AMD has the will to fight anymore. It's a shame as I've been an AMD customer for well over 15 years.
