Intel Core 2 Extreme QX9650 45nm Quad Core CPU
29 August 2008
Conclusion: The QX9650 is the first of Intel's 45nm CPUs and won't really see its full potential until more SSE4-enabled applications arrive on the scene. Still, it offers excellent performance, albeit at a steep price.
Pros: Larger L2 cache. Good overclocking potential. SSE4 instructions and architectural improvements.
Cons: Performance gains limited over current generation CPUs in current apps. Expensive.
Summary: As usual there's a hefty price on this right now, but the new transistor technology and larger cache seem to have given this CPU a nice boost over its predecessor. If you want the extra speed and would also like to do some overclocking it's worth considering.
Pros: 45-nanometre transistors, overclockable, new SSE4 instruction set
Cons: Current motherboard's may need a BIOS upgrade before this CPU will work
