Nvidia would have been the more logical choice for many reasons.
1. Close working relationship with AMD
2. Intel haters...no Intel business to lose
3. Fat juicy margins of 40% +...positive cash flow from the start
4. A combined Nvidia/AMD would have likely put even more pressure on ATI and produced even greater market share gains for Nvidia
The problems with the aquisition?
1. The price would have been at least $12 billion...over double ATI.
2. Jen has a HUGE ego and would have asked for the moon as far as the price and his position within AMD/Nvidia was concerned.
There is a theory, that I support, that AMD tried to purchase Nvidia well before they aquired ATI. The timing of this was at a MUCH stronger time for AMD share price and technology leadership (pre Conroe) but they couldn't get the deal done. That is why the ATI deal feels late, at least to me, and seems like a head scratcher to many.
The two biggest "why in the heck did they do that?" questions in the PC/semi market recently for me have been:
1. Apple goes with Intel to replace IBM for processors. Are you kidding me? AMD is lower power, higher performance and Steve Jobs is supposed to be savy about tech? Intel must have bought him off and God knows what else. Little did we know that Intel showed Stevie boy the goods before they were released...Conroe...Core2Duo. He was smart after all and we were just in the dark.
2. AMD buys ATI? Are you kidding me? AMD loves Nvidia! AMD and Nvidia are almost cobranded in most gaming rigs and tech sites. ATI=Intel...AMD=Nvidia....everybody knows that! Well it seems AMD DID try and buy Nvidia first but the price was too high and maybe Jen wasn't selling. So they settled for the runnerup...ATI. That makes more sense now to me.
