New Graphics Card

[John Desay]

Is there a difference between the GTX 780 SC that you guys are referring to and the GTX 780 M in the latest iMac?

 

[Matt Ryan]

The only nonperformance increase I've seen is NEAT VIDEO, still only giving me 2-7FPS but I don't think its GPU accelerated.


Tom

You have to select preferences in the neat video menu upon running (It's default is CPU only). You can then enable GPU acceleration, etc...

Anybody using this in a TB enclosure?

 

[Tom Chase]

Matt.

Thank you - I didn't see that...

Jamon - I have it in Mac Pro Chasis sorry.

 

[Jamon Lewis]

Thanks Tom, no problem. I was just wondering how this compares to a Rocket.

It can be recognized and run in tbolt enclosure. I know I know. But it can.
BUT thunderbolt is too slow for gpu. So yes. And no.

what are your thoughts on the new AMD Radeon R9 295X2

http://www.amd.com/en-us/products/graphics/desktop/r9/295x2

5632 cores and costing around $1500.

 

[Paul Provost]

I recently dumped my titans and replaced with 3 r9 280x 6gb in my cubix and they seem pretty great so far. Especially at $400 each. Have to be on mavericks though. I'm slightly concerned about nvidia support in Mac going forward. Maybe just being paranoid.
FYI the MSI versions I got came with a 6 to 8 pin power adapter included in the goodies bag so maybe they're good in a Mac Pro?

That looks really great, especially for those without the Cubix. Two GPU:s on the same card, and enough of ram.. nice indeed. Two of those to a Windows box and you'll get 3 proceccing GPUs and one GPU for GUI

gt650 single slot. thinking of changing to and for that too

so Resolve supports using Nvidia for GUI and AMD for image processing on MAC ?

the Windows config guide says "However devices running both NVIDIA and AMD/ATI hardware simultaneously is not supported on Windows Resolve systems."...

 

[Paul Provost]

yep supported on mac
used to have it the other way around - AMD in the mac and GTX in the cubix

Paul what speed you getting transcoding R3D with your 3 x R9 280x ?

Depends. Sorry but vague question gets vague answer!
But generally, 23.98 4k 16/9 full premium, faster than realtime. But there is a point of diminishing returns with gpu if your cpu can't keep up. From what I gather, gpu handles debayer while CPU does the wavelet decompression. That's my problem as I have a Mac Pro 12 core, but only 2.4ghz. I doubt my third gpu is doing much with r3d, but may be helping with NR or whatever in resolve. CPU is my bottleneck.

 

[roryhinds]

Thanks, yeah vague. 4K benchmarks are good to go on though.

What power draw are each of those cards? I see they don't need additional power and just run off the PCI power? I have a HPZ800 I'm thinking of putting a few of these in, if I don't go for the new R9 295x2

 

[Paul Provost]

6pin + 8 pin power connectors.
In a tower a double card like x295 or titan z probably better. Price premium though. And on a pc you have the x290 option, probably best bang for buck

 

[roryhinds]

with your cards are you running them as 3 separate cards or in some kind of SLI config? (AMD version of SLI)

 

[Jamon Lewis]

Anybody know which external TB enclosure will hold this card?

 

[Ian Planchon]

So I got this card today, installed all the latest drivers but am only getting about 14fps for playback. The card is installed in Slot 1 and plugged both 6 pins in. card is recognized, but still no real time playback.

any thoughts for the non techy?

cheers.
