Although we tested the Core i7 and Core i5 configurations on Gigabyte's P55-UD6, our Turbo Boost, Hyper-Threading, memory performance, and Windows 7 versus Vista power measurements were all taken on Intel's DP55KG motherboard.
Remember that we ran all of our gaming analysis separately in order to fit in single- and dual-card CrossFire and SLI configurations across two resolutions and seven different titles. That story can be found right here.

Dang! AMD better get their $4iT together. Now I need to decided between i7, i5 or phenom II when I do my next upgrade........technology happens too fast. Looking forward to more reviews on the i5 and mb prices.Reply
People need to be careful when comparing the i7-870 to a i7-920, alot of people pre-release were worried that the 1156 platform was going to dominate the 1366. However when you see the 870 out perform the 920 people need to remember that a 870 is double the price of a 920, and even when you factor in a motherboard a 920 setup comes out cheaper than a 870.Reply
Now the i5 750 on the other hand is great performance at a great price, and would certainly be the budget gamers new weapon of choice.
I currently have an i7-920 setup which is my main rig and am very happy with it and not at all upset to the see the 870 outperform it (since the 870 would cost me twice as much). I also have had an i5 750 setup now for over a week (the 1156 processors and motherboards have been available here in Australia for nearly 2 weeks now) and it is an amazing processor for the price of it.
So what am I trying to say? 1366 is still a good platform for the top end of the market. The i5 are fantastic new processors for their price, and the 1156 i7's are just confusing and I'm not really sure who they are going to appeal to? I could understand it if Intel launched the 1156 i7's in 6months time when alot of users are already using the 1156 platform and are looking to upgrade their CPU without a new mobo. But to anyone looking at getting a 870, just get an 920 and use the extra cash on the mobo and ram to go with it.
A little confusing the charts.Reply
I would prefer a bench with HD4890. They scale better in CF.
I can tell, I'm gonna fall in love with the i5 processorReply
Intel needs to come up with a simplified naming system for their products. They are as bad as NVIDIA is right now in terms of naming their products.Reply
There is sooo much to learn and there is so much information here.... I feel confused!!
Well, I just hope that the Core 2 Quads will drop in prices significantly so that I could grab the high-end one for my final LGA775 upgrade!Reply
Well this is good news for consumers. I'm not certain why it took so long for Intel to make some mainstream proc like i5, but for intel fans it seems worth the wait.Reply
This will also compel AMD to bring some more value to the market. Nice article.
damn, 150 watts at idle?? Is that just the cpu? I hope the gaming rigs built on these processors are not left on 24/7. My old AMD X2 3800 system including the monitor uses less than 150 watts at idle (50 of which is the 22" LCD).Reply
i7 Turbo is a good tool to monitor the multiplier of Core i5/i7 CPUs.Reply
It uses the method that Intel recommends in their November 2008 Turbo White Paper.
"Intel Core i7-920 Extreme (Bloomfield) 2.66 GHz, LGA 1366, 4.8 GT/s QPI, 8 MB L3, Power-savings enabled"Reply
Since when has the I7-920 become an extreme?
