Gtx 780ti vs gtx titan

[CaptainHook]

Just a warning about new Titans using the GK110B and the 780Ti - currently OpenCL is not working in OSX. Everyone is hoping for a driver update from Nvidia or Apple to fix. Cuda apparently still works, but Mavericks utilizes OpenCL quite a bit i've read (i'm still on ML myself) so be careful. If this could be an issue for you, try get the older GK110 Titan if possible or wait it out.

fec, Peter and all, major thanks.

Saved me a lot of headache with one thread.

Fec, did you use GTX580: GUI, Titan: Compute for your 4K test?

Ok I'll do it, but please wait for the next week...

The other thing i wonder about is say OpenCL performance of a R9 290X versus CUDA with a Titan in Resolve since the new Mac Pros will be OpenCL...?

Any thoughts/observations from the team Peter?

For others interested, Rohit tweeted this recently:

AMD R9 290 performance is impressive. Slightly faster than GTX Titan. Limited VRAM though - only 2GB usable by OpenCL/Windows

@StreamComputing @j_salvo Can get to a max of 3GB out of total 4GB, setting both to 100

haven't had a chance to explore on Mac. I suspect there won't be drivers yet.

So i'm still holding off on a Titan to see what happens, see if OSX gets support for the R9 290 and what performance is like, and if it gets a bump to 6GB ram. Plus the GK110b Titans still have issues in OSX anyway.

Great timing, Hook.

Was just hunting for Titans on this new build, an R9 and a cheaper GPU for GUI sounds really good/cost efficient.

But, were those tweets dealing with 4K?

Wonder if Rohit can comment.

[CaptainHook]

I think R9 will only be a better option for 4K than Titan if they release a version with more ram AND OSX gets driver support. Last thing Rohit tweeted about it was he could access 3GB of ram from it on windows. If you need something NOW, Titan is still prob best bet (just make sure it's not a GK110b version or you'll have issues in OSX with Open CL until that gets driver fixes too). But i think i will try be patient a bit longer until about march or april if i can. See what comes out.

Can someone explain what kind of issues people experiencing with GK and OS X?
Thanks!

[CaptainHook]

GK110A like in the first Titans is fine. GK110B like in 780ti and new Titans is not working with OpenCL in OSX at the moment. New drivers are needed.

Thanks!

Hi

The last time I tested thoroughly the GTX Titan, with HD, 4K, 6K, and BMCC 2,5k material.

My comments:

GK110 vs GCN (7970, R280) - only windows 8.1 - OSX have not tried


-If you have HD ProRes or DNxHD material, GCN architecture the best choise.

-If you're working 2,5K, RAW, then GTX 780ti, the best price/performance choise. (RAW debayer speed impressive)

-If you're working 4K, 6K then you need the GTX Titan. (4K debayer, temporal and spatial NR, 3node color correction, utilize almost all the 6GB memory)

It is interesting to the GTX Titan the lowest power consumption...

The GTX580 GUI+compute and GTX Titan compute combo, poor choice. Minimal performance (2-4fps) gain, and 120-150 watt power consumption and a lot of heat.

...one more comment:

If the Resolve scope enabled, GTX Titan drop 2-4 fps, the AMD GCN architecture scope enable or disable, no effect.

Beautiful Christmas everyone

Thanks fec, merry xmas to you too!

-If you're working 4K, 6K then you need the GTX Titan. (4K debayer, temporal and spatial NR, 3node color correction, utilize almost all the 6GB memory)

Are you still getting Realtime Playback in 4k with a single Titan this way?!?

How far do you think would a 4gb gtx770 get me?

Thanks for the detailed rundown.

Hi

Yes and No

Im not filmmaker, only one movie fans amateur, however professional PC hardware mechanic.

My PC is a custom bulit, special workstation motherboard Z9PE-D8 WS - ASUS and two 8-core 2,9Ghz xeon and 64GB ram. This config can realtime 4K RED Epic files with one Titan, but only light grading, and no NR and half resolution debayer, and almost realtime (20-22fps) the BMCC 2,5k full debayer 3node, and medium spatial NR(15).

The GTX680 and GTX770 one and the same, both are based on the GK104 chip.

My GTX680 4GB can not play BMCC prores/DNxHD 1080p realtime in minimal grade, and NR

I prefer to buy the GTX780 or GTX780Ti

I only have experience Windows environment...

fec

Thanks for the input, fec, I appreciate it.

I was also thinking on going for the 780ti, but I heard that going for 4k plus debayering, grading and NR would task the memory of 6g almost completely.

Have you tried doing 4k and all that with a 780ti?

I test it in the next month the GTX780/780Ti.
There will be results shortly...

This topic needs to continue.
How about that new Titan Black?

Looking perfect GPU configuration for BMCC RAW heavy stuff.

Hi guys!
What about 780M 4gb? My Imac 780M 4gb i7 350hz 32 GB RAM (the new one) have not yet touch 4K media. Will it performance well with 4k media?

Will it performance well with 4k media?

Forget about 4k, unless you want to spend 20k on a grading monitor.

Do everything in HD (there are more scaling options), then when done
switch back to 4k or whatever and render out.

There are affordable HD monitors out there. Look for one with a 3D Lut.
No edge backlight LED. Check out Lightillusion.com and FSI.

250€ upward single GPUs can do that, check out the 280x or
the 770 4gb or upcoming 780 6gb.

6GB 780

Thanks, that's sounds interesting. Should be enough then to work Raw with single GPU.......

Thank you for your help but, well, I don't have to own anything, my company have to. We already have a Dolby 4k. My question was about 780M 4gb card and how will it performance with 4k. We got 3 new iMac and 1 new Mac Pro for editing and CG for booadasting in Hd. Is there any test of 780M 4gb card in the new iMac and 4k Red media? We don't work, yet, with 4k BMCP camera.

What about 2 gtx780's with 3gb of ram each? Think that can handle 4k raw?

here's my tip, consider previewing everything in FullHD, you'll be fine with a single 280x 3gb ram or a 770 4gb a 2gb might do, too. Other options for the future, either a MSI Radeon R9 280X 6GB or a EVGA GeForce GTX 780 6GB.

two things for you to keep in mind. if you want 4k realtime you'll also need 1500 MB/s of storage. That's megabyte not bit! And 4k grading monitors cost atm 20k € upward.

also, an sli, crossfire or dual gpu doesn't mean the ram gets striped, like in raid 0. it get's mirrored, iow you'll loose half.

take all I said with a grain of salt. I'm not a colourist or have ever really used resolve. This is theoretical information my research and peers have produced for me. For colour calibration I recommend checking out http://www.lightillusion.com/

I should add that pro apps like resolve don't need crossfire or sli, since they are multi gpu aware. still my peers indicate that two time 2gb or ram ain't a combined 4 in the resolve world...

2 x 2gb of ram doesn't equal 4 total. But you don't lose 2gb. It's like the frames get split between the gpu's. So if 1 frame needs more than 2gb ram it won't jump over to the other gpu. But each gpu still can utilize all of it's 2 gigs. They just can't share.

Sorry to bust your research results, but one should never grade in HD then render 4K IF your delivery is indeed 4K, meaning it will be aired or played in 4K. Difference in sharpness between HD and 4K (UHD) is day and night, and you will not want to adjust sharpness of 4K image on HD preview monitor. Contrast, brightness, saturation, etc.. are no different stories.

It will if you install a gtx 780ti

Raw workflow:

GTX 780 6GB
vs.
GTX 780 Ti

What's the verdict?

Answer myself:

Titan Black

It's par with 780Ti, but it has that 6GB.
Little bit more expensive, but we need that 6GB for Raw editing.

However,
Nothing better is coming until 2015, we don't see 6GB 780Ti because Titan Black.
So, the next question is, and i'm hoping that someone would have tried these,

How about 2x 780Ti
vs.
Titan Black

I know it's been said, that it's better to have everything out of one GPU, but 2x 780Ti should be amazing, don't you think? Better than one Titan Black?

Well the Titan Z is better than the Titan Black and is out now, 12GB RAM, 5760 Cuda Cores, but is expensive.
Depending on your mother board 1 card can be better. If you use a Z series chipset then you only get 16 bus lanes through the CPU so putting in 2 cards will split the bus lanes between 2 cards. If you use an X79 Chipset or a modern Xeon then you have 40 bus lanes per CPU which allows for 2 GPU's running at full speed per CPU

I have been wondering here if 2 Titan Z used in cubix with mac pro 5.1 would blow my mind.

Any ideas on that ?

Which cubix?

Do not have any now.

I just have the idea.

Thanks Adbear,

I didn't include Titan Z because Ti and Black are almost identical, price, performance. Just a little difference, so that x2 Ti could be compared to Black...
Z is very questinable. Price/performance overkill...(?)

Why i asked this was the fact that now when red SDK is implemented in Resolve and i get rather good results with just one 780 in mac, got me wondering.

With Titan Z it could be possible to push "old" mac pro 5.1 at least year or two and be beefy as ever.

So if io and gnu would handle it we should have nice long life out of 5.1.

Price is always relative to the jobs you do so expense is not a consideration so much if
ones projects will justify it.

I wouldn't say so, when you consider that according to nVidia you should get the same performance in Resolve from 1 of these as you do from the 2 top end GPU's in the MAC Pro

As a matter of interest.
Do any of you have the ability of monitoring the upstream and downstream information passing through the x16 slots. If I had the time I would show you how much bandwidth was being used with two cards!
This banter goes on and on and on.

Radman.

Alright then.

Just for comparison, I found some prices for these cards (EVGA) in Europe

Titan Black @ 875 eur
780 Ti @ 595 eur
780 6GB @ 515 eur
Titan Z @ 2750 eur

You could find cheaper, and you can argue about EVGA, but those are very close to best deals for them right now.

x2 780 6GB, would give you 12GB for 1000 eur. Hmmm...

Yes maybe it would not be good ice or economical just the idea i was playing with.

Double Z in cubix.

It is a good deal, definitely, but it's not 6GB + 6GB = 12 GB. GPU Ram doesn't add up, but 6GB is still good of course.

The 780 6GB @ 515 eur looks like a sweetspot, on the other hand, I wonder how it performs, compared to a single card with double GPU, but lower memory.
