The new 975 Extreme has moved to Stepping D0, and we're told that the new 950 also uses D0:
We had a word with Intel and were promised a 920 on Stepping D0 that would do wonderful things in the overclocking stakes. We duly received a new 920 and it had exactly the same performance as our existing 920. CPU-Z identifies it as a Stepping C0/C1:
so we guess it's actually a C1. We then received another package and this time it was indeed a Core i7 920 D0:
less power = less heat = less cooling required
This means less noise, greater stability and potentially increased headroom for further overclocking.
power draw? who cares?
I am sure that sounds very mean spirited and anti-earth, but who is reading these evaluations? Dell? HP? Nooooo, people who are going to build a few machines at best and likely only 1, this year. They want maximum smoke ... as in speed.
Ok, I know that is is all pc to talk about crunch per watt, so fine.
Damn, no bitey ;-)
To be fair, if you are running [good] water cooling then it will probably go usefullyt further than a 920 - but even if I had a hypothetical £2k to wang on a rig, I still think that, say, three or four high end GPUs SLI/Crossfired up would make more of a difference than the Extreme. especially once the OpenCL-esque code starts appearing in a couple of years for GPGPU tasking - such as on Snow Leper, er, Leopard, etc.
That said, if I had £3k to spend...well, you're then in the position to start being a badge snob, and I'm always a sucker for that if I can when it comes to tech kit....
[PS: Should I come into £3k, I'll get your psychologists number...]
