Why is my GTX 980 so slow?

I just installed a GTX 980 non-EFI, and reinstalled the CUDA and web drivers from Nvidia. Everything seems to work great, except when I run Cinebench I get these results:

This can't be right. The 980 is slower than the 460? Not sure if there's some mitigating factor here I'm not seeing.

Cinebench is more a CPU benchmark. However, it has strange results. The winner of my Open GL comparison was an iMac 2011 3.4 GHz with Radeon 6970M, which makes no sense.

Hey my GTX 680 is not that bad, 58.13 points... :D

Better try Unigine Heaven and Unigine Valley Benchmark (preset 'Extreme'), and look here in the forum for comparisons.

Cool, thanks for the info. Given we (virtually) the same 5,1 system and the difference in GPU specs, your better score stumps me!

I'm sure in Unigine Heaven and Unigine Valley, in high resolutions (preset extreme), the GTX 980 will show it's strength and beat the GTX 680 without any problems.

Cinebench is ridiculous.

Peculiar. I've always felt that Cinebench gives fairly alright results for comparing chips, at least when staying with the same vendor nVidia/AMD/Intel

Ding ding ding !!!

This is the 100th time I have posted this.

All NVIDIA cards in same machine will get nearly same score. Either Cinema4d gets no use from NVIDIA GPU in OSX or Cinebench is an awful predictor of NVIDIA GPU performance in Cinema4D.

About once a week I get an enraged email from someone about this. Two or 3 days ago it was someone whose 980 did far worse than the 5870 it was replacing.

The "benchmark" hardly changed from v 11 to v 15. Same wire frames with new car skins to make it look new.

Cinebench is a great predictor of what you will see inside Cinema4D(with both AMD and Nvidia cards). Only things it can not predict is the behavior of the GPUs using large scenes/textures, but for average scenes or simple one like in the car benchmark what you see is exactly what you'll get in your viewport in everyday job.
It is funny to see how some people here prefers gaming benchmarks instead of professional bench for predicting OpenGL speed in pro apps. Gaming benchmarks just shows precomputed stuff, while in 3d editing softwares everything has to be processed by the CPU at first, and that's why OpenGl tests like Cinebench are so dependent by the CPU speed.
All GPUs installed on old MP are bottlenecked by the slow CPU performance for viewport tasks so they will only reach a fraction of their potential and it's no surprise that all reach about the same score when installed on the same machine. To see some real gains in your viewport you have to increase the single thread speed of the CPU(one of the biggest limits of the old MP). Of course this is only for viewport editing in 3d software, for most other usage(like running OpenCL/CUDA) their performance should be mostly unaffected by the slow single thread of old machines.
I've see plenty of people upgrading GPU hoping to get a viewport boost in C4d or other 3D packages, but eventually all of them do not get the big speedup they where hoping for..(except for the more memory of newer GPUs that let them handle larger scenes, but slowly). Also be aware that different drivers can speedup or slowdown things considerably inside Cinema4d, so better to choose recommended drivers.
