post #14451 of 38701
If someone would be willing to run 3DMark 11 Performance test with stock HD7970 (925/1375MHz) I would be very thankful.

12.7 beta drivers and default settings in Catalyst (please don't disable tessellation)

I have a HD7950 @ 1000/1500MHz , so I would like to see how much is there difference compared to a stock HD7970.

Here's my 3DMark 11 P score with HD7950 @ 1000/1500MHz, beta 12.7 drivers.

3dmark depends to much on other factors for a comparison to be truly fair. Just know that if u clock ur 7950 to 1050/1400, you will be equaling or just a bit better than a 7970

On 1 GHz you will equal to stock HD 7970.
I have personally tested that.

HD7950 @ 1000/1500 is exactly 22% faster (GPU score) in 3DMark 11 than stock HD7950 @ 800/1250MHz.

1000/1500MHz 3DMark 11 run

800/1250MHz 3DMark 11 run

So I believe that already HD7950 @ 1000/1500MHz is equal/or maybe faster than a stock HD7970 (925/1375MHz).

I just want to know exact P score of stock HD7970 on 12.7 beta drivers.

You're missing the point. Your CPU speed, your ram and your background processes all make a difference. A brand new windows install can add 500 points alone to someone who hasn't reinstalled windows in 2 months

No sir, you're missing the point.

And that two 3DMark 11 scores are my,on the same rig with identical CPU OC and drivers, so I know for a fact that HD7950 @ 1000/1500 is 22% faster in GPU score than stock reference HD7950 (800/1250MHz).


I see you have 3 x 7970, instead of pointless discussion you could've disabled CF, set GPU speeds at 925/1375 and ran P score 3dMark 11.

He will have way higher P score, because of i7 3960X.
You need to look at GPU score, and GPU score with SB/SB-E/IB cpus for right comparison.

You'd have to disable PowerPlay to eliminate software throttling (that I know of).

That's why I think 480x480 and 320x320 have errors, they don't throttle for me... 480x480 at stock volts(1.09) 970 stable no throttling, and 320x320 if I go to 1100 mhz/1.23v. I watch the clock in MSI AB, HWinfo64. I also watch 12v current IN, and VDDC current to see at which resolution I get the highest current. GPU% lies, because if it throttles, it still counts that as 100% usage.

Can you run the 480x480 and 320x320, dx10, error checking on, shader 8, tests for me and tell me where you get errors popping up as compared to your known good overclock? I may very well have a dud card, who knows- if you pass those occt 4.3.1 tests at the same speed that passes games/benchmarks.

I contacted the OCCT creator, and mentioned my observations. He says that lower resolutions do stress the card more when cards throttle TDP, because if you run full res, you can see in MSI AB, it's basically throttled down to 700-800 mhz!


There are bioses that i found that seem to have a higher throttle limit, as seen in OCCT4/3/furmark/kombustor, by watching FPS and 12v Current IN.
The Sapphire 900mhz BIOS 1 on techpowerup, the sapphire 950 mhz bios, and of course the 7970 bioses (but they mess up my hdmi output- nothing detected). There may be other bioses, but I haven't tested them all, nor want to, LOL. IIRC, I was maxing out at 18 Amps 12v Input with stock bios, with the Sapphire bioses, along with the 7970 bioses, I could get the GPU to draw up to 23 amps! That is an extra 60 watts... oh and yes the PSU and PCIe power connectors handle it, stays above 11.8 v as seen as GPU, despite the card having only 2x6 connectors!

I agree with his contention that manufacturers that throttle cards are doing a disservice. Example, Heaven 3.0 and some other benchmarks, they saw that 7970 bios on 7950 would get higher scores at the same clock (by a little bit). I saw the same difference in scores between the stock gigabyte bios (that seems to have the stock 7950 max TDP, vs the sapphire bioses, that don't throttle as soon. I wonder if sapphire made a special bios for themselves, knowing that their VRM phases and cooling can handle it? I know my gigabyte can too.. very solidly built (but no VRM HEATSINK ***!?)

CHEERS..

:facepalm: come on man...please reread what I said. I don't care what scores you have. You are asking US To test OUR 7970s on OUR machines. My machine is completely different from yours, thus, it is not an accurate score because of the differences between our machines.

And I never even argued over what scores you have so I have no idea why you keep telling me you saw a 22% increase in performance and seem to think that I don't believe you or something.

Nice rig jomama22 thumb.gif Did you add all 3 7970's at the same time? Reason I ask is I am wondering if you noticed a difference going from 2 to 3 and if so how much.
