AMD hoped that its line of triple-core processors, the Phenom X3 series, would compete with Intel's Core 2 Duo range of a dual-core CPUs.

This is the slowest member of the X3 family we tested, at 2.1 GHz, and we found it to be around 15% slower than the next model up, the 2.3 GHz X3 8650.

That means that it takes 8 minutes 46 seconds to encode a DivX video file instead of 7 minutes 29 seconds.

Product Face-Off

The X3 8450 is less powerful for 3D gaming, too, only managing a frame rate of 23 fps in World in Conflict against 28 fps on the X3 8650 and 32 fps from Intel's Core 2 Duo 37200.

In terms of our physical measurements of the X3 processors, we were rather disappointed by how much power they used: this one caused our test PC to ramp consumption up to 206 W while idle and 286 W at full speed.

For comparison, the Intel Core 2 Quad Q8200 rates at 161 W and 222 W respectively for these two measures, and the Intel Core 2 Duo E7200 155 W and 195 W respectively.

  • Very fast for certain tasks


  • Two slow on most tasks
  • Very high power consumption


AMD's line of Phenom X3 processors can be very good if you limit your usage to certain applications where they perform well. In general, they did poorly on most of our tests, and used a lot of power.
