I'm sure a lot of people wants to know how Nehalem's Core i7 will stack up against a Penryn (Yorkfield and Wolfdale). So I'll use the same set of benchmarks I used to compare P45 vs X48/X38 in x-fire to see just what it looks like on a home setup, no Extreme Edition or LN2 or crazy GTX 280 tri-SLI, just setups regular folks use for gaming ;)

Setups will be:

Core i7 - Bloomfield

Mobo - Asus P6T Deluxe X58
CPU - Intel i7 940/i7-920
GPU - GTX 280 SLI

Core 2 - Penryn

Mobo - Abit IX38 QuadGT
CPU - Intel Q9650 ES
GPU - GTX 280 SLI



Benchmarking will commence this weekend, Nehalem setup will be up and running this weekend or early next week

As can be seen from these results the i7-940 setup had no improvement on gaming benchmarks, so all in all it seems that only synthetic benchmarks, encoding and other CPU intensive applications will benefit from the Nehalem platforn thus far. If you want to game, do everyday stuff with your PC, stay with LGA 775 daulies and quads.

thanks brolloks!!

i have to ask though are you going to be doing sli/cf or just single card per clock? i think that single card isnt going to work to compare the two platforms. as we can see per clock i7 is faster. even assuming at 16.7% increase in i7 as a low side number for clock to clock comparsion. [email protected] = [email protected], if you move i7 up to the same clock(ie 3.2ghz) then it equals 3.73ghz C2Q. im waiting to see if the number % wise matches up to what i figured. since we had to figure the % difference for core2 to equal a Amd setup. looks like we need to do the same agian.... i still say the biggest draw back gaming wise for i7 is the 256k L2 vs 4/8mb,6/12mb L2 on "core 2" quads.
 
I'm planning to do one card and with clocks that Jason suggested actually in another thread.

i7 940 ~ 3.6-3.8 Ghz
Q9650 ~ 4-4.2 Ghz
E8500 ~ 4.3-4.5 Ghz

I do not want to go SLI/CF just yet, will see how these results turn out before I embark on dual cards, my aim is to keep it closer to what most folks use.

I'm open to more suggestions on how to make the comparsion more realistic, so thanks Dr Evil for your comments/suggestions :)
 
This will be good.

I'd also suggest to list the approximate price of each setup but I guess we could just calculate that ourselves (depending on availability/location).
 
Well, I'd say from an overclocking standpoint it would be fair to compare the max OC of each. But since it might take a long time to find and stabilize the highest OC for each system, the initially planned clocks by Brolloks seem ok to me. Maybe do those clocks and then also do an 'even overclock number' between all of them like the 3.8ghz proposed above.

Power Consumption comparisons would also be cool.
