GTX 970 / GTX 980 are here

[BoomR]

My EVGA GTX 970 seems to be working fine on my office 1080p LED panel (via DVI and HDMI). I bought a $75 Monster super-high-end HDMI cable and connected my GTX 970 to the HDMI 2.0 port on my new VIZIO 4k HDTV (which has one HDMI 2.0 port).

In the Display Prefs panel, I can set resolution to 4k, and the refresh rate shows 24Hz, 30Hz, and 60Hz in the drop-down list! YAY! (screen grab to come)

BUT...when I go to set 60Hz, it crashes the System Prefs and I get no video... BOOooo ...OR, it doesn’t always crash the preferences panel, but just doesn’t output at 4K@60Hz. If I change inputs and connect the video card to to one of the TV's 4K@30hz ports, I get video again (4K@30Hz).

I'm going to install Win7 on a separate disk, and then try to see if my 4K Vizio will do 4K@60Hz under Windows. If that's the case, then I fear the issue may be OS X related...

UPDATE: Installed Windows 7 Ultimate Edition on a separate drive (disconnected my OSX Drive). I can now confirm that my EVGA GTX 970, in conjunction with my Vizio 4K display can indeed do 4K@60Ghz. Here's a screen shot:


Just to clarify, it did both 3840 X 2160 and 4096 x 2160 - at 60Ghz. So this tells me:
--The video card works as advertised (it is not defective), and
--The Vizio 4K UHD also works as advertised - HDMI port 5 labeled HDM 2.0 (4K@60Hz) functions properly.

A couple things I will try next to get this same performance under OS X: a) I may try NOT using the NVIDIA drivers, and use their utility to switch back to the native Apple drivers; and b) try something other than macpro 6,1 for system definition.

Hey

I haven't tried the display port yet as my monitors don't have a display port input. I'll probably try a display port to HDMI/DVI adapter soon.

Really hard to tell if the 0db mode is working will try to find out.

EDIT: All 3 monitors do actually work now after updating the nvidia web driver (1 HDMI / 2 DVI). The DVIs are running at 120Hz

@dangermouse76

So you get the full performance of the card (no problems) but you can't use the display port?

also, does the 0db fan mode work?

Sorry there is no quote, it would not let me for some reason.​

Regarding performance, here are some benchmarks:

so opencl almost doubles 770's. sweet.
can you tell me whether the graphical glitches are eliminated?
and can you confirm that i have to wait for cuda? i need to make a quick decision i've got like 12 hours)
thanks! =0)

Is it possible that 4K @ 60Hz does not work over HDMI because there is no actual mac that has an HDMI 2.0 port?

I thought of that, but then I thought with the NVIDIA drivers, that might "override" that limitation & provide the functionality.

I can confirm that the HDMI port on GTX 970 does, in fact work (it's not malfunctioning), as it does drive my 4k set at 4K@60Hz. So I suspect the issue is with Mac OS X. I may try a different smbios - like iMac 14... more testing to come

Hello,

I saw that someone was looking for some GTX 980 LuxMark results so here are mine.

My config is the following one:
z97x-UD5H
i7 4790k
GTX 980 Gigabyte G1 Gaming
16 Go 2400 MHz

Thanks was looking forward to seeing how good the 980 was, any chance you could do the BruceX test in final cut pro X please.

Ok - I had to Google that benchmarking test. I'm no expert by any means when it comes to GPUs (well, ANY of this stuff, for that matter). Wasn't sure which of the "scenes" you wanted me to run in the test, so I just picked 3. I'm sure you know more about the specs for each of the scenes - so here are the results:

Luxball-Sunset:

Luxball-HDR:

Sala:

Again, my specs:
ASUS X99-Deluxe
Haswell-E i7 5930K (3.5 Ghz)
16GB G.Skill DDR4-2666/PC4-21300
Samsung 850 Pro SSD - 250GB
EVGA GeForce GTX 970 SC (ACX 2.0) - 4GB
Yosemite 10.10

Your thoughts?

Thanks BoomR, these new cards from nvidia are certainly a big improvement regarding OpenCL rendering in final cut especially the new 980. Nearly double the speed over my 780, i can feel an upgrade coming

I've just installed a GTX 980 here. However, I cannot get CUDA to work. I've installed the CUDA drivers, but when I open Cuda-Z, it says CUDA not found. Anyone know why?




Oh, and also there's something strange about the CUDA preferences. It says Update Required, but also No newer CUDA Driver available.

I don't have any graphical glitches whatsoever.

Regarding cuda, no luck there yet.
