So here is the thing, i just got a new core i7 and after running a few benchmarks such as the Far Cry 2 benchmark and 3DMark06 and for some reason my set up before with the Phenom II got a better score

here are the 3DMark06 Scores
Core i7




Phenom II




So why is the score so close when i have a better CPU ?

More about : core phenom 940

Last i checked 17332 was better than 16486. The i7 is scoring about 1k points more, what did you expect?

It's a 3d benchmarking program, processors don't play much role in the score.

Processors do play a pretty large role but not when the processors are that close in performance.

I have 3 8800GTX ACS3 cards and almost reach 20,000. I am running a Q9550 which is comparable to the PII.

Whats the BB Code to paste pics on the post again? I can never remember it. I will post my results once someone tells me, lol...

here ill show you another score


Phenom II







This score is better then the core i7 score

you need a photbucket account to do so (or so i was told) and i would really like to know how come im getting such a a low score with the i7 !

The 2nd score had the 4890 overclocked.

If you are running the same video card at its max capability from the cpu, you cant expect much more of an increase from any cpu upgrade if the cpu can't unlock anymore potential from the video card.

Also, you can run the same bench mark 12 times and get different results with the same setup. There are a lot of variables that effect the score.

The 2nd score has the 4890 overclocked somehow. Maybe fusion for gaming is running. Just check the SM3 scores in each, the cpu scores stay the same but in the one where the 940 scores highest, the SM3 score is a lot higher. That's a gpu overclock doing that.

Ok so what do you think i should do if the score is almost the same should i just return the core i7 or is it just the 4890 holding it back ?
July 31, 2009 2:41:29 AM

btw what im seeing in the photos look at them for the second time the CPU score is 1000 higher so does that mean what i said before that the GPU is holding it back ?

It's fine. A top end Phenom II will be pretty close to an i7 920 in 3dmark06 because at stock values they are almost identical in power.

When you overclock the i7 you will get much higher scores. The i7 scales a lot better in 3dmark06 when overclocked. Try upping it to 3.6ghz or something and you'll be close to 20k 3dmarks.

Are you for real ??? if I OC it to like 3.6 it will jump that high from 10K to 20K or even 15K?

You're already at 17k at 2.8ghz. Yes, if you overclock the i7 to 3.6ghz it will probably get close to 20k 3dmarks.

I have a phenom II 940 at 3.6ghz, and crossfired 4770's, and I get 20k 3dmarks. The i7 @ 4.2 ghz with the same cards scores 24k 3dmarks.

Another example is cjl's 4870x2 and i7 scoring 17500 at stock, and 24k with the i7 overclocked. 06 is old now and the i7 seems to take advantage of how it works, and with a high overclock you will get to huge scores.
July 31, 2009 3:06:14 AM

lol i just reilized that i do get 17K its Vatage i get 10K with but i dont seem to have a Key for it so i cant get it to work. im overlocking it now and going to run 06 and ill post the score in a few minutes

You'll break 20k without too much trouble, perhaps needing 3.7ghz or 3.8ghz but it shouldnt be difficult to get that on any i7 with a top end gpu.

I don't think 3DMark06 is much good at using 8 threads so the Phenom II will come close as jennyh said. But CPU score is not very important in the grand scheme of 06, your SM2 and SM3 scores are.

The game score used in the calculation is 0.5 x (SM3.0 + SM2.0)
3DMark06 score = 2.5 x 1 / ((1.7 / Game score + 0.3 / CPU scores points) / 2) rounded to the nearest unit.

The two bolded dividers are the important details here. The CPU score has a much smaller weighting than the game score, and your game scores are virtually identical for both rigs, so the final score will be similar.

For your i7 system:

0.5 x (SM3.0 + SM2.0) = 7335
2.5 x 1 / ((1.7 / 7335 + 0.3 / 5289) / 2) = 17332

For the Phenom II system:

0.5 x (SM3.0 + SM2.0) = 7273
2.5 x 1 / ((1.7 / 7273 + 0.3 / 4313) / 2) = 16485

Actually, it's even more dramatic than that. It's 24k at 3.73GHz (my normal daily use speed), and 27k at 4.2GHz (my benchmarking, Crysis, MATLAB, and Solidworks speed). Of course, that's a pair of 4870x2s, so it's basically completely CPU limited even on the graphics tests in 3dmark06. Still, overclocking the CPU is definitely worth a try.

Well i have the i7 @ 3.4 lets see whati get !?

Nah leave the 4890 for now, you can oc it once you get the i7 to it's highest.

That's only 3.2ghz, you can go higher. My 19600 @3.6ghz is out the window however.

Windows 7 is hurting it, I lost about 1k marks when I switched. You will get to 20k no problem, it just needs a bit more juice :)

Hm I'd go with that instead of the futuremark one then. Try 3.8, dont fry it tho :p  And yep no reason why you can't add 100mhz to the 4890 core for a test.

That's easy, the problem in'st your CPU, the problem is the program 'cause the DB of the program don't have another system like yours with a i7.....I have the same problem with my Phenom II X4 955
July 31, 2009 4:14:57 PM

Well here is the main question should i return the CPU or is it working ok and i was just stupid to get a i7 when i have a phenom II x4 ?

That depends. For some people, it's worth it. For others, it's a waste. Do you see enough of a speed benefit to justify it in your opinion?
August 2, 2009 6:38:41 PM

Well i dont think i see a good enough improvment now but i think later in the year games will start benefiting from the architecture of the Core i7 and the Hyper Threding is that a true statment ?

By the time games really need 8 threads you'd have 8 native cores and 16 threads at the very least. FSX is, as always, an exception.

-----------------------------

Not really, the 940 is really good, but whe you put both in the scale, the i7 is better that the 940.....maybe the "problem" is that you don't wait much time to try the potential of the 940...
August 3, 2009 3:31:22 PM

buy a second 4890 and try it on both platforms.

You wont see any improvements over a Phenom II in games. 3DMark itself is not a perfect judge either of it. Only games truly can tell you.

And the benefit of a Core i7 normally wont show until I would say the next gen of GPUs or multiple of current GPUs.

If it was me, I would stick with the Core i7 for the future. It will take some time for it to truly be fully utilized and hopefully it will be able to be a drop in CPU upgrade cuz even current GPUs don't fully saturate a single PCIe 1.1 x16 bus and wont for a PCIe 2.0 x16 buss until the next gen of graphics slot comes out.

Isn't a secret, i say in another reply.....the phenom can't compit with the i7, always will win the i7, inclusive...in some bechmarked the phenom is defeat for the core 2 quad....but i'm an AMD client...
August 5, 2009 4:12:14 PM

Well the i7 hands down has more brute power than the X4, but for games, I personally don't see the benefits from the i7 to be worth it....however, if you are using your comp for photo/video editing or rendering, then the i7 clearly pwns....

my 2 cents

btw: PsychoSaysDie put up a pic comparing the i7 and other processors to a Phenom I....now that's just plain mean...lol...
