Frankly speaking, the Phenom is a lot closer in performance than A64 was to C2D. The stock price only continues to plummet while ATI's division hasn't looked this good in the last 2 years. AT the end of the day, you don't necessarily have to have the best product. AMD's biggest problem in my eyes has always been marketing and complete inability to get the average person to get excited about their products. I have never seen any clever in store presentations, commercials or any ad in any magazine. Just something simple as putting 5 AMD rigs at Best Buy and 5 Intel rigs and running a videogame would show consumers that a 10% difference in performance wasn't actually "felt" in gaming.
Even still, everyone knows marketing and sales can overcome a product that isnt the best -just look at AAPL. So at least AMD could have provided "cool factor" tower and notebook designs for their offerings...again they didnt do anything.
Unfortunately AMD was always run by engineers who were good at what they did for a while. But for 4 years after A64 all they could come up with was Phenom? That was just unbelievable. However, this is exactly a scenario that requires marketing to help you get to the next cycle. You need both successful engineers and marketers to have a truly successful company. Take any brand you want, whether it's SBUX, Coca Cola, NIKE, etc. That doesn't mean marketing and engineering will be enough to be successful, but without them, you are almost guaranteed NOT to be.
So my concern is despite Dirk being the new CEO, his background is one of an engineering not a marketer -- something AMD needs now more than ever.
