Testbed and Methods

As we have already said, Phenom X3 processor family falls “in-between” Phenom X4 and Athlon 64 X2. Therefore, besides the entire Phenom X3 line-up, we have also tested the top dual-core AMD processor and the youngest Phenom X4 model.

On the competitor’s side, we will have dual-core processor from the same price range. After the recent price reduction these are two youngest models from the Wolfdale Core 2 Duo family including the new Core 2 Duo E7200 CPU. However, since there still are some availability issues with 45nm CPUs, we have also included older 65nm representatives of the Core 2 Duo family.

The testbed configuration is given below:

AMD platform:

• CPUs:
  • AMD Phenom X4 9550 (Socket AM2+, 2.2GHz, 4 x 512KB L2, 2MB L3, Agena);
