The fastest dual-core and quad-core processors from AMD and Intel go head to head in this performance comparison at Digit-Life (Intel Core 2 Duo E8500; Intel Core 2 Extreme QX9770; AMD Athlon 64 X2 6400+; AMD Phenom X4 9850):
The top processor from AMD is outscored by the top processor from Intel by 45%. There is actually nothing to comment on. We could have added "we have food for thought now". However, there is nothing much to think about.
Do you want to know what clock rate the Phenom X4 must have to catch up with the existing Core 2 Extreme QX9770, even if we assume that Phenom performance grows strictly proportional to its clock rate? The current clock rate of the top Phenom is 2.5 GHz. The target clock rate (according to our total performance score) is 132/91*2.5=~3.6 GHz. So, in order to reach parity with Intel, AMD has to raise the clock rate by 1.1 GHz. Given Intel is not launching any faster processors that is.
