"... make sure you're running in a 64-bit environment if you want to come anywhere close to taking advantage of this platform's potential in threaded software. ... What we can say definitively is that the Xeon X5680—despite running 133 MHz faster than Intel's older Xeon W5580—operates more efficiently than its predecessor in threaded software. It's significantly more complex, what with its two extra cores and 4 MB of extra L3 cache. But it fits within the same thermal envelope thanks to 32 nm manufacturing, and even manages to use less average power ..."

"... In a bid to reduce power consumption, Intel Xeon X5600 series CPUs can in essence gate off unused cores and shut them down to reduce power, saving their state in cache. ... If virtualization or highly threaded workloads are your game, the six-core Intel Xeon X5600 models are definitely the way to go. If you're looking for raw clock speed on single-threaded workloads, the four-core models will give you better bang for your CPU buck. For the power miser, or those wanting to cram lots of lower-power CPUs into a rack, the 40-watt chips may be right up your alley. In essence, there seems to be a Westmere chip to fit just about every scenario."
