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.
Compare the AMD Phenom X3 8450 with the Intel Core 2 Duo E7200 and other CPUs in our
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.
