Phenom X3 8450Let's have a look at the exterior of the processor.
(Click to Zoom)The chip was assembled in week 8 of 2008, which makes it a fairly new processor on the market. The X3's are basicly X4's with one core disabled, be it because it's broken or isn't capable of working at a frequency that's high enough to sell it as an X4 model.

(*): We downclocked our E8500 to run at stock E8200 speeds for easier comparison.
(*²): At the moment of testing, our Commando board was no longer available, so we used a P35 instead.
MethodologyThe following benchmarks were used:
Lavalys Everest: Memory latency
SuperPi 1M
Wprime 32M
Wprime 1024M
PCMark05
TechArp X264 HD benchmark
Cinebench 10
3DMark2001SE
3DMark06
Prey
Crysis
We ran the CPU at stock settings and overclocked at 250HTT with the standard multiplier applied, which is 10,5x. The memory settings were identical to those we've used in the quadcore article, so:
Stock at 200HTT: 533MHz 4-6-6-22(*) - Unganged
Overclocked to 250HTT: 500MHz 4-4-4-10 - Unganged
Both ganged and unganged are dual channel memory settings, but in ganged mode the memory is seen as a 1x128bit block and in unganged, the memory is seen as a 2x64bit block. Ganged has more synthetical bandwidth, unganged is overall faster.
