The Phenom II X4 810 & X3 720: AMD Gets DDR3 But Doesn't Need Itby Anand Lal Shimpi on February 9, 2009 12:00 AM EST

The Economic Problem
For the consumer, AMD's pricing strategy is incredible. For AMD and its shareholders however, the pricing is a bit tough. The Phenom II X4 940 is priced similarly to the Core 2 Quad Q9400, a chip that is 36% smaller than AMD's offering. The Phenom II X4 810 goes up against the Q8300, again, a chip that's 36% smaller. The Phenom II X3 720 is even worse shape; AMD is selling a chip that's 258 mm2 at the same price Intel sells a 82 mm2 chip; that's a 68% smaller die at the same price.
|AMD CPU||AMD Die Size||Competitive Intel CPU||Competitive Intel Die Size||Intel Size Advantage|
|AMD Phenom II X4 900 series||258 mm2||Intel Core 2 Quad Q9xxx/Q8xxx||164 mm2||36%|
|AMD Phenom II X4 800 series||258 mm2||Intel Core 2 Quad Q8xxx||164 mm2||36%|
|AMD Phenom II X3 700 series||258 mm2||Intel Core 2 Duo E7xxx series||82 mm2||68%|
AMD in many cases delivers greater performance than the similarly priced Intel CPUs, but not nearly a large enough performance gap to make up for the difference in die size. Again, great for consumers, but potentially painful for AMD in the long run. As yields improve AMD should be able to make more of these cores members of the 900 family, but without a separate, smaller die there will still be economic inefficiencies at the lower end.
