Have said it before and will say it again...
...thank Intel for delaying 22nm E5/E7 Xeon's.
If you consider the fact that servers need to last a good many years it does make one hell of a difference in power and cooling costs when you compare 22nm versus 32nm. And even as we speak right now Intel's 22nm E5 Xeon parts are STILL not out.
Yes, I'm aware that they'll hit the market in Q3, but the fact is this delay has caused us to pretty much eradicate all server upgrades over the past 15 months. And I know I'm not the only one.
After all the primary benefit for me to upgrade my servers is to reduce power and cooling costs. Performance is a plus point, sure, but it's a secondary benefit for most part.
