So does anyone want to weigh in on the i7's. I know their hyperthreading is the shiznit but in real world performance, how much more work do you get actually get done. I though I had read about 20%, but maybe as high as 30%. Does that sound about right?

Not to make you change your choice, simply to state the facts: when I have run these tests it was with HCC WUs because they are the more consistent as far as duration is concerned. With other projects you can never know if a WU runs faster because it ran better or because the work to do was smaller. More details on these tests are there comparing the quad core 2.4ghz to the p4 3.2ghz - and the i7 After the tests I have finally chosen Rice or normal work because I prefer when WUs are not lasting too long, not because HCC was causing problems. Cheers. Jean. Well I've decided to give CEP a run using both virtual cores in the P4 2.93 I have here. If it comes up as you say, then I guess I have a little back-tracking to do.

Well I've decided to give CEP a run using both virtual cores in the P4 2.93 I have here. If it comes up as you say, then I guess I have a little back-tracking to do. Mine has contributed about half of my gold badge, with only one error (I think) which was in the same vein as errors reported by others during the launch of CEP. Be ready to see these WUs running high priority most or all of the time... and to last many many hours. Cheers.

Someone must have an opinion on the i7's. Are there any reviews that focus on comparative crunching ability?

I think I read that when it was first posted, but he says
----------------------------------------From the brief numbers I can see it looks like this machine at 3733mhz will pull just over 20,800 points a day with HT off and well over 30,000 a day with HT enabled. For comparison a Q6600 machine at 3600 will pull between 15,000-16,000 a day. That's a 50% improvement on cpu intensive tasks. Maybe that's true, but I could have sworn I had seen numbers that were in the 20-30% range. Still impressive though. Also, that was for a 965 - that's out of my league. A 920 would be more my speed.  Then when you consider the price, a Phenom II might be a better deal. |
