Phenom Models and Details, Continued

AMD Phenom vs. Athlon Core Shootout

We were particularly interested in AMD's claims of Phenom performing up to 25% faster per clock than the recent Athlon 64 X2 processors. Given that there hasn't been any architectural revolution like the one that Intel initiated when switching from Netburst to Core, a 25% performance enhancement per clock is significant. It even appears a bit hard to believe, which is why decided to have a close look at the new processor. We compared the Athlon 64 X2 and Phenom 9900 at a 2.6 GHz base clock speed, using only a single core.

Phenom CPUs
Name Clock Speed L2 Cache L3 Cache TDP
AMD Phenom 9700 2.4 GHz 4x 512 kB 2 MB 125 W
AMD Phenom 9600 2.3 GHz 4x 512 kB 2 MB 95 W
AMD Phenom 9500 2.2 GHz 4x 512 kB 2 MB 95 W

Phenoms all look alike: this is our engineering sample, which is multiplier-unlocked.
