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

[Brolloks]

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.

Some runs on the 940 and 920

[White_Pawn]

can't wait brolloks.

[w2richwood]

looking forward to this first hand thank's brolloks.

[Evilsizer]

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. i7@2.66ghz = C2Q@3.2ghz, 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.

[Brolloks]

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

[don'tknow]

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).

[Mr.Guvernment]

this will be good to compare vs [H] results and guru3d that have their benchs up.

Kudos to that. Good choice. Real life tests.

IMO it will be fair if you compare them clock-per-clock with a decent OC. Let's say something like 3.8 GHz.

Hmm...I'd say, put the Nehalem at 5 GHz, the Yorkfield at 5.5GHz, and the Wolfdale at 6.

...oh wait...wrong thread.

[don'tknow]

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.

Can't wait!

Subscribed!! This'll be fun and VERY informative. Thank you Brolloks

What's all that supposed to imply?

ooooh

Alright good There is more then one of us in the house with early access to Intel stuff

[w2richwood]

btw what kind of cooling you going to be using on the i7 chip

Wow, since when do people game, fold, 24/7 use their PC's with LN2?

[Shiggity]

Yay, finally some trustworthy overclocked results. Gettin' pretty sick of these stock results.

<3

[Badbonji]

I am just wondering what ram will you be using and how many channels for Nehalem?

[Brolloks]

I will bench on air untill I can get a 1366 adaptor for the GTZ, will also use regular DDR3 untill I get the tri-channel sticks.

[Shiggity]

the diff in dual channel / tri channel is pretty much 0 anyways (under 5%)

Looking forward to a great weekend. Thanks bud.

hahahahahaaa.....I'd love to try though, some method of directly plumbing from the gas farm to me. j/k

Seriuosly though, these chips are going to be great for people with cascades. I'm going to start looking for a builder as soon as I get back from LA.

[ozzlo]

Yes, I am interested in seeing some pure Clock for clock comparisons.

If your not using multiple graphics cards I can already say the results gonna be within 5&#37; for gaming but I'm still interested anyways.
