Ah, finally some competition. It's good to see AMD coming out of the gate strong and forcing a move by Intel. Hopefully this time Intel properly tries to compete. Last time AMD had a hit, Intel strong armed OEMs into making AMD disappear from their products.
On a side note, I can't help but notice some irony in AMD's product line. I still remember when Phenom launched and AMD poked at Intel for their quad cores being a pair of 2 core dies on one chip with AMD having the only "true" 4 core die; now here they are with 2 4 core dies in one package.
I do understand why, of course: parts commonality/modularity. it's easier to design the 4 core complex and mix and match it with 1 or 2 complexes for their CPUs and adding a GPU for the APU lineup, than to have separate 4 and 8 core dies like Intel does.
