brettjv's 470 SLI vs 670 Bench-Off (both OC'd) ... (Now with 7970 OC'd!) - Page 13

Poll Results: What are you thinking: Used Fermi for SLI, or go with Kepler?

 
  • 18% (20)
    Thinking of getting adding another cheap, used Fermi for SLI!!!
  • 64% (70)
    Thinking of selling my Fermi and going with Single High-End Kepler (670/680)!!!
  • 17% (19)
    Thinking of waiting to see what lower-end/cheaper Keplers bring to the table!!!

Sorry to disappoint you ZK ... I think I may have figured it though. Gimme a few here ...

AFA my tests go in the OP, they're still legit, apples-to-apples for the 470's vs the 670 ... now we're just trying to run down why a few people here have so much higher scores than others ...

As Brett's i7 920 is at 3.9GHz, perhaps people using a SB can downclock to ~3.9GHz and rerun the Crysis benchmark? This should provide a more accurate comparison between 670 vs 680 vs 7970 etc by minimizing the CPU factor.

Okay, starting to buy the CPU hypothesis a bit more, based on these results ... I forced resolution to 1080p and AA down to 4x in the game and re-ran. The resolution definitely changed, I got bars on top/bottom. However, the FPS gain (around 5%) seems awful low ... it's like the AA level really didn't change. However, there's more signs of CPU BN as my usage is definitely down vs. my earlier run, which was at 1920x1080 and (probably) 16xQAA.

The thing that's confusing is that there's NO SIGN of the AA level in the config file at all. Does anyone know where the 'master' config file is for Crysis, the one that you can manually change and it results in the 'generated' config (the one in the Doc/Saves) getting changed?

364

Of course, the fact that the Benchmark tool is totally broken for me causes me to wonder ... is everyone else's results totally accurate as well thinking.gif

I'm still not convinced there's not something inherently different between how this bench runs on Arni and Dimmy's systems, vs. Youra and mine's. His and mine 'make sense' in terms of the perf difference to me. The difference between ours, and that of Dimmy and Arni ... really doesn't to me. Youra is rocking a ton of CPU power, and similar clocks, but he's only around 4% ahead of my last run here, which makes sense as a CPU discrepancy, mitigated slightly by my higher GPU clocks (I'm at 1325/1800 on these last few runs) headscratch.gif

I'm wondering if there's any sort of mods involved ... mine is pure, unadulterated Steam install, totally untouched.

Also ... Dimmy and Youra, what DRIVERS are you on?

OK, I tried deactivating Turbo which puts my clock speed at it's stock of 3.4GHz:
570
About 10% decline in performance.

The CPU is no problem. With Core i7 920 @ 4.2Ghz and 2 x HD 6970s i got 80fps 1080p AA, I got 83fps with 2500K @ 4.8Ghz. Also try to change the slider in the Crysis in-game settings. I thinks its for View Distance.

@Bret: I'm on 301.10 WHQL. I don't know, I just showed that going from Nehalem @ 4.0 to SB @ 4.6 (all other things the same) netted 12% increase in FPS. As for why I'm THAT faster, my guess would be your 3.9 Nehalem vs 4.6 Sandy + my extra SMX cluster + drivers? They are diff revision for 670, aren't they?

I gotta go to work, but I say we switch to some Warhead testing. At least I know that damn tool works.

Do Frost, 4xAA, 1080p, maxed settings. I'll run 'em when I get home tonight ...

Now, this I didn't expect biggrin.gif
Almost 25% faster than a 680 in warhead.

I'm trying to install Crysis 2, but Origin is messed up.
