GTX Titan …. now I’m confused

[Alex Elkins]

I was talking about Mac Pro. And Paul, I think you’re probably right about processor speed being the bottleneck these days, particularly for Macs. Here’s hoping the ‘Spring 2013’ rumours turn into something positive…

I’ve been told by a couple of people that I can expect very good performance from the 3x GTX 680 cards (50fps with 10 nodes on 4K R3D or something similarly crazy), which really is not going to have me complaining any time soon! I’ll believe that when I see it though. Just thought it was worth checking if people thought the Titan card would be significantly better.

You most certainly can’t expect anything close to 4K 50fps from any hardware in r3d, unless you’ve got like four red rocket cards to do debayering.

Yeah I did have my doubts! Still, should be quite a bit faster than the Apple Color system I’ve been using.

Really helps with tracking, blurs and nr on r3d

Helps even more if you get the hell out of R3D.

So trim r3d
Render to 4k dpx
Proxy at hd?
For all projects?

I don’t trim the r3d.
And rarely go to a 4K intermediate, unless I’m delivering 4K.
No proxys.
Only for wholly red projects, if it’s 1 or 2 red shots, I’ll live with r3d.

First reports on the Titan (anandtech, tomshardware) say that it is faster than 680 (by ca 50%) and slightly slower than 690. If you are on Mac and the GPU limit is three (not counting GUI) it is probably better to have 1xGUI + 3x Titan (equal to 4.5 x 680) than 2×690 which works out to 1xGUI and 3x 680. In other words:
1x GUI + 3 titans give you 50% more power than either max configuration with 680 or 690.
Also 6GB VRAM is way better for resolutions >2K than 4GB from 680, not mentioning the 2x2GB on the the 690.
NDA from Nvidia goes off thursday and more detailed reports will be released.

First Titan Benchmarks (though testing video games) have arrived!

According to this Article the Titan is the fastest single GPU card at the moment but looses to the GTX 690 in the benchmarks…
Thought it would turn out to be faster, but still waiting on some hard resolve facts here. Maybe a dual GPU Titan some time down the road with ass whooping 12Gb of vram?

And you propose to cool this proposed dual-Titan GPU monster how Nicholas??? 😉

Robert’s numbers above appear correct. My recommended Xpander model for hosting 3x or 4x GTX Titans external to the host machine is the new Xpander Desktop Elite, which features a 1500W power supply, variable speed temperature controlled exhaust fan, LCD front panel status and control buttons. Same price as the Desktop 4 part numbers.
