Low performance for dual GTX 770?

GTX 770 - Half performance in osx compared to windows??

Hello,

I just added 2 GTX 770's to add some new life to my aging hackintosh and did a clean install of 10.9.2 (been running 10.6.8 for a little over 3 years now)

Everything seems to be working fine, installation went smoothly, however my graphics performance is significantly lower on Mac compared to Windows 7. I've tried the benchmarks on 10.9.1, tried with the latest nvidia web driver, latest cuda driver and nothing seems to make much difference. So I'm just wondering if there's something I'm missing or I'll just never be able to match my computers Windows performance on Mac?

Comp specs:
X58a-ud3r Rev 2
i7 970 6 core @ 4.2GHz
6x 2GB corsair DDR3 1600 triple channel
2x Zotac GeForce GTX 770 AMP! 2GB
1x EVGA GTX 470 1280MB

Benchmarks
LuxMark 2.1
Windows 7 - 3911
OSX 10.9.2 - 2159

Cinebench R15
Windows 7 - 116 Fps (no difference with sli enabled/disabled)
OSX 10.9.2 - 44fps

The weird thing is I built a friend a brand new Hackintosh a month ago (Z87X-UD5H, i7 4770k quad core @ 4.3GHz, 2x 8GB G.Skill DDR3 1866, MSI GeForce GTX 760 OC 2GB) and that got around 106FPS in Cinebench R15 on OSX 10.9.1 and I don't recall doing anything different... You would think a 770 should be able to out perform or at least match a 760...

Could Cinebench possibly be using my GTX 470 to do the bench mark even though it says GTX 770? If so is there any way to temporarily disable the GTX 470 without physically removing it from the comp?

Anyway not a big issue, was just hoping for some input.

Thanks in advanced,

-Marcel

Remove GTX470 and test again, but I think it's your CUP and motherboard causing low scores in cinebench.
You should test those two cards in yours friend computer to see if I'm not wrong

I guess I'll have to give that a shot then if there's no way to just temporarily disable the GTX 470.

I don't think it would be the CPU causing low scores because it still gets a 10% higher score then then my friends 4770k on Cinebench. Perhaps the Mobo though, although scores are fine under Windows, so that seems unlikely unless Mavericks just doesn't like old hardware?

My friend lives about an hour and 15min drive away so chances are I'll never get around to testing the video cards in that comp haha.

I did 1 other benchmark this time on Unigine Heaven 4.0 just to see if it was a Cinebench issue but I got similar results.
Unigine Heaven 4.0 - Basic Preset
Windows 7 average FPS - SLI Enabled - 148 (Score 3729) - SLI Disabled 131.2 (Score 3305)
OSX 10.9.2 average FPS - 84.5 (Score 2130)

Also tried Geekbench and that result was almost the same in OSX and Windows so it has to be something OpenGL related.
Geekbench 3
Windows 7 - 17308 (2948 single core)
OSX 10.9.2 - 17056 (2387 single core)

Ask your friend to benchmark Cinebench in Windows. We will see if it is hardware issue or better drivers in Windows.

There's no Windows on my friends comp. She wanted strictly Mac only. I was tempted to actually go there and test my card in her comp the other day but then I looked up the dimensions and it is actually physically too big fit into the computer haha. It's a small case. So so much for that idea.

Anyway Heres is my latest batch of testing in a single card/single 1920x1200 monitor config.

-GTX 470:
Cinebench OSX - 50.25 FPS
Cinebench Windows - 106.81 FPS

Luxmark OSX - 619
Luxmark Windows - 947

Heaven -Basic -OSX - 66.8 FPS (1682 score)
Heaven -Basic -Windows - 74.8 FPS (1885 score)

-GTX 770:
Cinebench OSX - 50.7 FPS
Cinebench Windows - 110.38 FPS

Luxmark OSX - 780
Luxmark Windows - 1529

Heaven -Basic -OSX - 84 FPS (2117 score)
Heaven -Basic -Windows - 143.7 FPS (3620 score)


So it seems like either the Nvidia Mac drivers are extremely terrible or Mac is throttling these cards for some reason to about half speed...?

It's strange that you are getting lower results in OpenCl benchmarks. Mine is getting preety same results in both platforms.
Your Luxmark score is strange in Windows as GTX 770 never go above 700-800 pts both in OS X and Windows.

As far as OpenGl performance in OS X is concerned Nvidia perform worse than in Windows.

Mine GTX780 in cinebench has:
76 fps in OS X
110 fps in Windows

Hmm Not sure why my Windows Luxmark would be so high then. Perhaps Its just the new Nvidia drivers have much better openCL Performance then the ones from May 2013 that were being used in that benchmark.

Just did a comparison between all my cards:
Luxmark Sala Windows 7

Just 1 GTX 770 Selected - 1523
Just the Other GTX 770 Selected - 1453
Both GTX 770's Selected - 2960
Both GTX 770's and the GTX 470 Selected - 3830

Thought maybe it was benching the cpu too even though its greyed out in windows but it does seem to scale accordingly between 1 and 2 cards.

Guess that good that its not just me seeing a big drop in performance between windows and Mavericks. Hopefully future updates will fix that.

One thing I just noticed was my Cinebench score on the GTX 470 under Snow Leopard was 64 FPS and on Mavericks is 50 FPS so that's like a 22% decrease in performance from a so called "upgrade"... Good job Apple.. lol

If only Snow Leopard supported newer cards..


One thing that still makes no sense though is why is a GTX 760 significantly out Performing both our cards in cinebench on the same operating system... You would think all cards would get crappy performance unless apple is purposely crippling higher end cards for some reason...

Reviving this

I'm running GTX 970 on my hackintosh and can't get a higher score than 69.7FPS in Cinebench R15.

Any clues?

 

[dvl_iac]

I never did find a solution and just accepted it haha. I haven't updated since 10.9.2 but perhaps the newer versions of mavericks or Yosemite or even just the newer Nvidia drivers may fix the problem?

I haven't had the time or desire to experiment with those.
