GTX 690

Has anyone installed a GTX 690 video card on a mac yet. Supposed to be supported in OS X 10.8. How did you deal with power connections? Does Davinci Resolve see both GPUs and use both GPUs? If this works, seems like a no brainer to install this next to a GUI. You get two GPUs in one double PCI slot.

Thanks!

As per the config guide, the GTX 690 is supported in an expander chassis, due to power needs.

Hi Peter,

thanks for the Info. Does Resolve/OSX recognize the two GPUs on the 690?

Maybe not that helpful answer from me. But Resolve 9 on my windows box does recognise both GPUs in my GTX590 and utilize them. So, I assume that the same would go for 690.

Hi neo, how to tell how many gpus have been detected in resolve 9? Thanks.

Go to Resolve -> about resolve. It should pop up the information in the summary tab.

Actually, have a look in the menu bar, DaVinci Resolve, Preferences, System Overview.

Hi

I have gone through the configuration specs and a question about Davinci Resolve and MacBook Pro and grading Red 2 or 4 K footage.. And will be wanting to grade BMCC 2.5 K raw.

Can I hook up the GTe 690 via Sonnet Echo Express 2L Thunderbolt Chassis to either 15" retina 16 GB Ram with 750 SSD or 17" early 2011 with 750 HDD and 4 GB Ram, both Mac OS 10.8.2.

Appreciate feedback as I am new to Resolve and Raw files and want to integrate with existing Mac gear.

Thank you Joshua, but it looks like Peter is right

Got it. Thank you Peter

Hi RobRic, You can not use a GPU via Thunderbolt as there are no drivers and insufficient bandwidth on the current version of ThunderBolt.
Peter

Thanks Peter for clarifying that.

This is how Resolve Lite 9.03 read the GTX 690 on a Mac OS X 10.8.2

Yep. Same as with the 590. THe 690 actually works better internally in the mac than the 590 since it draws less power. When I stress tested the 590 the Mac cut the power but that never happened with the 690 for me. That being said, for a dedicated resolve rig I would NOT go for the 690 since it's not a fast card when one GPU is locked for GUI (actually, the 6-series is not a fast series. period.). 570/580 gives almost identical performance when you benchmark it.

Hi! Would like to ask you the same about the power connections? Did you use a special adapter cable?
How is the performance of the 690?

You need to convert form 6pin to 8pin, there's cables for that.

Here you can get a hint about the performance compared to other cards:

The spreadsheet is great info-
wish I could find a similar comparison for mobile GPU's as I am considering a Sager or other Windows gaming laptop. The mobile GTX 680m looks promising. There is a new model that supports dual GTX 680m in a laptop config that supports 3 hard drives, mSATA and up to 32GB of RAM. Wish Apple would get the picture when they see those kind of specs.

Question remains:
How did you get the 690 to work in a Mac Pro? Or is it a hackintosh? As I understood that the Mac Pro power supply could not handle the GTX 690?

I have a 690 and a quadro 400 inside my machine (hackintosh) running Resolve Lite.
400 is GUI only, but still getting around 22 fps playback (and the GPU bar almost fully red) on 1080p 24fps prores4444 (even with no nodes). The speed is just a tad slower if I run Resolve gui too on the 690. Also makes no difference if the footage is on RAID or on internal hdd.
But render hits 60fps and more...

[CaptainHook]

Resolve Lite won't use more than 1 card for GPU and since the 690 should show as 2 i don't think you will be getting the max benefit from that card with a quadro running GUI anyway?

Also, what motherboard in your hackintosh?

If the other slots share the x16 lane adding more cards may half it (x8) making it pointless anyway. I found that out the hard way as i have a Gigabyte Z77X-UD5H and i get the same results (fps) using my GTX580 as GPU and a GTX550ti for GUI as i do just using the 580 without the 550 plugged in (i assume since having the 550 in cripples the 580 by half).

Have you tried with just the 690 plugged in ?
My hunch is you could ditch the quadro 4000 completely (depending on your board and if you stay with Lite).

I have just set up a system and was wondering if I could run two GTX690's in a Cubix with another 2 x Red Rockets ?

Running Full Resolve 9.0.4 or 9.0.5 being released today ?

Mac Pro 2.93,
12 core,
64GB RAM
SSD OS w/ Mountain Lion
4 X 2 TB's in Raid 5

Slot 1 GUI is using GTX285 and running two 30" cinema displays
Slot 2 Cubix with 2 X 690's (trying to decide if this will work) and 2 X Red Rockets
Slot 3 Decklink Extreme is running a Dreamcolor and also a 50" Plasma, both for reference
Slot 4 Raid Card and customized for using HDMI Decklink adaptors

I know 2 x 680's will work with 2 x red rockets and I am considering getting a 690 now and another later to complete the 4 slots in the cubix.

I've been figuring out how to use Resolve and it has been an awesome experience. Are there many people in here just starting out like I am?
If anyone knows about if these 690's will work in this set up, please let me know.

You could do this setup, but you would be wasting half of one of the 690s in Mac OS. The macs are limited to 3 processing GPUs and the 690 actually show up in the OS as two GPUs a piece. So putting 2 in a cubix, would only allow you to use 75% of their total processing power. I think 2x690 would equal the performance of 2x580... which is kind of a waste. Though I should say I haven't actually tried this config.

On windows OTOH, you can have up to 4 processing GPUs. So in a PC config you'd be able to use the full power of both 690s... this give you performance roughly on par with 3x580s. I've got a test system configured this way right now. And will write more about it, as soon as I've finished testing.

Hope that helps.

Asus z9pe d8 board and ya, I know about the shared pcie lanes, and no, I'm not sharing them (at least not where I need 16x)
I think I tried with only the 690 and it ran the same... Now I'm seeing a somewhat normal speeds when I close the WF display (had it open before, silly me). But still more often than not the GPU bar hits red, fps still tells me 24 but I actually see some lagging.

[CaptainHook]

I actually noticed some lagging today when i was testing footage from my BMCC and it still said 25fps to me as well. Haven't had time to try figure out reproducible steps yet.

Thanks for the tip. I went ahead and used 2 X 680's in the cubix with 2 X Red Rockets.
I understood what you said about the 690's having 2 GPU's per piece and it really clarified everything for me.

Thanks again
