Anyone put them up head to head in resolve?
Anyone know of a flashed bootable version?

"Anyone put them up head to head in resolve?"
Yes. The Titan is about 50% faster than 680. It's about 85% as fast as a full 690. If you're using an expansion chassis doing high res work. Higher than 3K. Then the Titan is your best bet. But it doesn't work on the Mac. Works fine on windows and Linux though.

How do you mean?

If you don't mind me asking, how did you get those results? From what I've read they were designed for different purposes and the Titan should theoretically be faster in resolve. (But slower in 3d stuff.) It's design should theoretically be more geared to cuda stuff. Also it's a single chip vs the 690 dual chip, which resolve may like better. (Or may work better in a cubix.) So I was surprised by your results.
You actually tried both cards?

Flashing referred to putting Mac boot firmware on the card so it would load. But like you said, no drivers yet :(

I've got several of both cards. They are different classes of chips, the Titans are GK110, 690s are GK104. The 690s are basically two slightly slower 680s sharing one board.

The advantage of the 690s is the combined processing of multiple GPUs, if you're running in a MacPro for example, and you put in one 690 and a GT120 or similar for GUI, using a full resolve license, you'd basically have the equivalent of 2/3rds of a cubix with three 680s available to you. Without having an external chassis.

The disadvantage is that the 690s only have 2GBs of RAM per GPU. This can become troublesome for larger image formats.

The Titans on the other hand are based on a different chip. Which as I mentioned doesn't have driver support on the Mac, but which has a significant processing improvement over the GK104, as exhibited on my Resolve linux system. Even better though is the 6GBs of RAM, which not only seems to improve performance, but also reliability with large images.

But like I said, in terms of performances, 1 Titan = ~1.5 GTX680s (plus lots of ram), where as 1 690 (meaning two seperate chips on the same board, with both chips working together) = ~1.8ish GTX680 (with a limited amount of RAM). On the Mac, once you get into expansion chassis the 690 looses it's advantage as you can only address 3 gpus on the Mac, and each 690 is two gpus. So with two 690s you loose half of one card. Titans on the other hand offer great performance and are only address as one GPU, so on systems that support it are ideal for an expansion chassis.

Cool thanks Juan!

According to Netkas, 10.8.4 beta has Titan drivers. So thats nice.

Are you saying this is only using three GPU's on my Mac? GUI card is a Radeon 7950.

Fascinating. So unlike prior version of Mac OS X, 10.8.3 OS is supporting more than 4 video cards. I've booted(with giant caveat) with 5, but 6 cause my system to kernel panic on boot.

Prior version had a software limitation which only allowed the OS to address 4 cards. It was once suggested to me that this was related to a hardware restriction, that efi boot only had enough memory to address 4 cards. It seems that software limitation has been lifted. However the hardware limit still seems to exists. At least it does in my 2010 MacPro.

So I'm able to boot with 5 cards, but the system is basically unusable this way, it works in fits and starts. Seems to be choking on everything I do. I'll have to see if the 2012 version has addressed this in some way. Though regardless of whether it has or not this is good news for those using hackintosh, as they've never had the hardware restriction only an OS one.

John, are you actually using your box day-to-day with 4 cards? Do you find it stable? Seeing any crashes, kernel panics, freezes?

I use it everyday and have zero issues. EFI is an interesting tidbit as I am using non flashed PC cards, EVGA 4GB GTX 680's. This is why I use the Radeon 7950 for GUI, that way I get boot screen. I only use the 4 GTX 680's for CUDA. Performs way better than my Supermicro Maximus PC with Quadro K5000 and Tesla K20. I use it with After Effects and Premiere Pro as well.

John, are you on resolve 9.1.3? I've got three of the same cards in a cubix on a 2012 Mac Pro and am now very curious about adding a fourth. Would come in handy when ofx support is added...

John,

Do you use the 680 and the 7950 with a cubix or can they both live together in a MacPro?

I am looking to replace my old 120/285 combo and trying to see what are the best performance/cost at the moment.

Looking at slot requirement, I am not sure it leave space for BM card and any storage card.
Is my best bet is the 680 for GPU and 4000 (single slot) for GUI ?

isn't the GUI card usually listed in System Overview, along with GPUs and Rockets? i'm currently on a single card system, so i can't check.

Wait, you can run a 690 in a mac pro with stock power? I thought the TDP for a 680 was the limit?

Also, 9.1.3 shows my GT120 as the GUI in the system overview. Then the 570s are listed separate (as GPUs).

Mac OS X does already support 4 GPUS. But not 5. At least that's how it used to be. Still looking into it.

We are looking into this as well. We have managed to run a GUI GPU + 2 GTX 690s in a Cubix chassis as well as 5 GTX 680s (1 GUI + 4 GPUs in Cubix).

So far we have not run into any issues. But we are still performing tests and will let you know what we find.

Thanks,
Anish

So based on comments from Anish and Rohit, I tried two 690s (4 processing GPUs) in a Cubix in 2010 MacPro again, this time doing an SMC reset, and jackpot! It seems to be working fine. All the cards show up and I'm getting playback, OS seems solid. This is pretty huge.

Juan,
Might you know if, with OS Mavericks 10.9, it is possible to run a Titan in a Mac Pro 5,1?
If yes, which product? Thanks!

Not using mavericks. Likely won't be for some time to come.

Juan,

I have been waiting for Mavericks because of its extended openCL support. (But also not switching yet.) Without it Programs like Premiere won't open. Are you using 10.9 drivers in your 10.85 build for Titan support?

Not using special drivers. Not using Titan on GUI.

Great news, thanks for sharing guys!

Curious as a fellow 2010 MacPro 12-core user, with or w/out a cubix4 what the 'highest' build specs will be moving forward?

Titan or 690 depending on whether one does or does not have a cubix?

Thanks again for the news and research everyone.

Presently the best performing config for Mac would probably be 4 GTX680 4GBs in a Cubix. 690s are two slightly slower 680s sharing a card.

curious to see how much of a hit the 2GB (per GPU) 690 would take on 4k footage vs the 680 cards with 4GB of RAM.

4 GPUs in only 2 slots is incredibly tempting though. or a 690 card in a Mac Pro with a separate GUI card. thats a lot of power without needing a Cubix

What about the Titan card...theoretically speaking if its going to work in 10.8.4, wouldn't that yield better performance over the 680?

What I don't understand in all of this....

is how the Cubix Expander is not limited by the PCIE 2.0 bandwidth with 4 cards stuck in a Cubix Expander.
