Gtx 780ti vs gtx titan

PostThu Nov 07, 2013 4:30 pm

Now that Resolve v10 is final (!) a new question arises re top gpu option.
Gtx 780 ti has been released today @$700. More cores, faster than a titan @$1000.
BUT, titan has 6gb ram with the 780ti at only 3gb
And what about titans higher dual precision / FP64 performance? Does that make a big difference in resolve and ofx.
question to resolve team is:
since Titan is essentially eol I would guess, and likely a bad purchase at this time at that price - is buying the 780ti going to be a disadvantage performance wise?

reason I ask is because I've got two unopened titans in front of me I'm considering returning...

I like the Titan's.

As a matter of interest though, I have never managed to get Resolve to use more than 1.2G's of Open GL memory. ( 1920x1080 ). More memory for GUI allways a good thing it seems.

Cheers, Radman.

I don't believe Titan is EOL primarily due to having the 6GB RAM.
If you plan on using higher than HD, or Temporal processing, plugins.. etc.. more GPU ram is better.

I'm kinda faced with the same dilemma. I was waiting for the price drops to happen this month (which they did with the 770/780) but it hasn't happened (yet?) with the Titan.

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?

The AMD OpenCL performance in Resolve 10 very good:

Encode DNxHD 1080p to DNxHD 1080p , 1 node color correction + noise reduction medium 15:

Asus HD7970 3GB: ~36 fps (GPU ~ 80-85% / CPU - 10-25%)

Asus GTX580 1,5GB: ~21 fps (GPU ~ 95-99% / CPU - 15-25%)


Encode cDNG 2,5k to H264 2,5k, 1 node color correction + noise reduction medium 15:

Asus HD7970 3GB: ~15 fps (GPU ~ 40-45% / CPU - 10-25%)

Asus GTX580 1,5GB: ~13 fps (GPU ~ 90-95% / CPU - 20-25%)

Indeed, different memory architecture, but the memory usage is no more than 1000-1300MB a 1080p material.

...shortly 4GB GTX680 test results.

I understand Peter to imply, "...all other things equal." It seems clear that a Titan with more CUDA cores and more GPU ram is better than a GTX 780 with fewer CUDA cores and less ram.

I'm curious as to the tradeoff between a GTX 780 3GB (more cores) vs. a GTX 770 4GB (a little more ram).

I know there is no "one size fits all" solution here. Assuming HD (not 4k) and temporal processing, I wonder whether the slight advantage in ram (for the 770) wins out over the core advantage (for the 780).

Yes Frank :)

A GTX680 4GB slower than GT580 1,5GB when noise filtering and encoding if the focused !

The old GTX580 dual precision (DP) performance very good (DP=SP/4), while the GTX680 single precision (SP) floating point performance brilliant, but DP only 1/24 the SP.

http://www.tomshardware.com/reviews/geforce-gtx-780-performance-review,3516-28.html

The situation is being changed, when they have memory intensive heavy grading.

I'm guessing but it seems reasonable to assume that DR uses just single precision floating point operations only.

The reason the GTX580 is still a good card is because each core is clocked at twice the speed of the Kepler architecture cards (GTX680, Titans etc.). Also GTX580 has a bigger memory interface width (384bits to 256bits in GTX680) so can fetch more data in one go.

If you are doing 4K work, I think you need 4GB GPU RAM or above. So I don't expect GTX780ti will be any good for 4K stuff. Titans would be a better option I believe.

When programming in CUDA, you're not constantly thrashing the GPU RAM. You want to avoid accessing RAM (called global memory) as little as possible as its slow compared to on chip local memory. You generally transfer all the data into local registers/memory and then do calculations. So more RAM if not used, won't help. Hence for HD work I'd expect a GTX580 with just 1.5GB RAM will be pretty good. RAM above that probably rarely used to give any sort of advantage.

I think the exception is if you start to use any of the temporal functions in R10 like optical flow, temporal NR, motion blur, etc - or OFX plugins. It will cause out of memory errors with that kind of ram (speaking from experience).

Frank - just concurring with others here, i've seen identical performance between 5xx and 6xx series EXCEPT when using NR where the 5xx is faster even with less ram.

fecxxx - Thanks for posting those performance results, would love to see the Titan/R9 290X when you get them in. :)

But yeah, since I plan to build some new workstations, I'm really interested in real world comparisons between AMD and Nvidia, now that Resolve and Premiere can use both.

Re: Gtx 780ti vs gtx titan

The vicious tug of war for dominance between graphics card manufacturers AMD and Nvidia NVDA +6.98% continues today with the launch of Nvidia’s GTX 780 Ti, a $699 card billed as “the best gaming GPU on the planet.” Thus begins a series of articles determining if enthusiast gamers can put their faith in that claim, and whether or not AMD’s R9 290x should be part of that discussion.

First, let’s glance at what the 780 Ti is packing. Nvidia’s GK110 architecture is fully unleashed here, its engine powered up with all 2880 CUDA cores, a base clock of 875MHz, and a boost clock of 928MHz. On the memory side we have 3GB of GDDR5 running at 7.0 Gbps and a 384-bit memory interface width.

What’s fascinating about these specs is that on paper AMD would appear to have a definitive edge with their R9 290 and R9 290x cards, which have an additional 1GB of memory and a wider (512-bit) memory interface. But the combined memory bandwidth of the 780 Ti (336 GB/s) eclipses the R9 290x (320 GB/s).

In my preliminary testing, the GTX 780 Ti unequivocally outperforms Titan and turns in a victory against the 290 and 290x. What remains shadowed in uncertainty is how wide that performance gap is between Nvidia’s new flagship and AMD’s Hawaii GPU.

You’ll notice there aren’t thorough benchmarks present in this article, and I’m going to explain why.

Earlier this week, Chris Angelini of Tom’s Hardware reported that he was seeing wild variances between press-supplied versions of AMD’s R9 290 and retail versions of the same reference card. Here’s an excerpt:

“The card that AMD sent to me is a stallion. Even if you get it nice and hot before running a test, bringing it down off of that 1000 MHz “wishful thinking” spec, it’s still faster than GeForce GTX 780, and oftentimes GeForce GTX Titan. But the Radeon R9 290X I bought from Newegg is a dud. It’ll drop to 727 MHz and stay there…and the reference cooler still can’t cool it fast enough. The result is that it violates its 40% fan speed ceiling as well. The craziness, then, is that my R9 290 press board is typically faster than my R9 290X retail card. ”

AMD's R9 290
AMD's R9 290 is outperforming its big brother 290x in my testing -- that doesn't seem right

Why is this noteworthy? The 290x costs $549, while the 290 costs $399. More troubling is that my own tests back up what Angelini is seeing. In Heaven 4.0, for example, the 290 is turning in 9% better DirectX 11 performance than the 290x. That gap stays consistent and even increases with games like Dirt Showdown, Grid 2, BioShock Infinite, Batman: Arkham City, and Tomb Raider.

So unless AMD decided to undercut themselves and render the 290x obsolete weeks after its launch, something is fishy. Thus, I’m hesitant to publish the results I have just in case this variance between press and retail cards turns out to be true. And the only way to confirm that is by purchasing a retail 290x from NewEgg and conducting my own tests on both versions.

The findings will be crucial, because although the 780 Ti is the undisputed victor in terms of performance, there’s a $300 difference in price between Nvidia’s latest offering and AMD’s R9 290; $150 divides the 780 Ti and 290x. Determining the true gap in performance between these two cards is vital to rendering an ultimate recommendation, and I’m not comfortable doing that until I have all the facts in front of me.

[An AMD representative told Tom's Hardware that "there's a discrepancy between absolute fan speed and its PWM controller." The company is working on a fix via a software update, but I want to see what consumers are dealing with right now in contrast to benchmarks being reported on the press side. I've also contacted AMD for further clarification on this issue.]

Don't know if " Grid 2, BioShock Infinite, Batman: Arkham City, and Tomb Raider" benchmarks are helping to judge Resolve or Premiere performance.

I think a representative from BMD should give Paul a proper answer to his question.

I'm wondering on the same thing, cause I'm doing some research for a tutorial on this subject.
What I heard is that 4gb of RAM is the sweetspot for 4k, and that you want a single GPU card,
possibly a gtx 760 4gb might do the trick for HD. But I'm wondering if BMD is going to drop cuda
in the long run for AMD cooperation...

Here is some relevant quotes by Peter Chamberlain (DaVinci Resolve Product Manager):
"...with v10 there are more processes that use GPU ram and if you think you will handle footage with higher than HD res this GPU RAM is even more beneficial than before."

"OpenFX plugins (and temporal proc) are optimized for single GPU and so it´s better to have one fast GPU with 4GB ram rather than two 2GB cards. Even adding a second 4GB card won´t double plugin performance. This is a limit of the OpenFx standard and the GPU structure, it´s not a Resolve limit."

"Don´t think 2GB cards are useless. All our NAB demo systems used 680 or 690 or iMac 2GB cards, I´m just giving everyone background on why 4GB of GPU ram will become common in the future as resolution and temporal/plugin demands request more from the GPUs."
"For GPU ram, 4GB is our current expectation for regular 4K work using v10."

Just assembled one grading suite with mac pro latest maxed up 2012 BTO, dropped two titans in cubix expander, extreme 4K and red rocket.. Guys can't drop rig under realtime performance with red footage/debayer maxed out.. What we did for testing.. We can even grade realtime while playing timeline with more then 10 nodes pasted on every shot.. Maybe overkill but I hope its future proof.. For a while i guess..
So bottom line, Titans works pretty well in this configuration..

I had an example today where a user had issues with his 3GB GPU. He was using optical flow and spacial noise reduction with a 4K timeline and 4K source images that also need the GPU for debayer... .all was good on an HD timeline but a 4K timeline runs out of GPU ram... thus the good and practical application for Titan or the FirePro W9000 as both have 6GB GPU ram.

As I mentioned before, its better to have one Titan/W9000 than two lower GPU ram cards if you plan to use NR, Optical Flow processing, OpenFX plugins and 4K.

All as per the config guide.

Me too. I'm trying to decide between going with CUDA or OpenCL. Seems like the market will eventually shift to OpenCL as developers don't enjoy maintaining two code bases.

It's a rigged market (like most markets really if you know what I mean). So no, I think in my opinion it won't happen.

Today we arrived at the titan card.

DISAPPOINTMENT !

For the time being in the 7970 the best buy, and the GTX580 the best performance/price ratio :cry:

Interesting, thanks fec. Could try the 7970/GTX580/Titan with the Temporal NR instead of just spatial? Titan should do better here apparently due to extra ram but would love to see real world results.

Now that's quite interesting.

Great thread, thanks for the tests.

Sorry to jump slightly off topic, as far as brand goes, but is there a reason why the W9000 is suggested over the W8000/7000?

Both seem to spec out great for 4K, NR, etc. but it looks like the Titan's preferred?

More RAM, i guess same reason Titan is recommended over 780ti etc. Although Vlad from Neat Video recommended to me just yesterday that the 780ti performs better in his testing and makes more sense right now since it's cheaper. I assume that's not taking into account Neat Video inside resolve and memory requirements there etc (i just purchased OFX neat video to avoid going to premiere to use it) so there's more to consider.

The next test:

Dual GPU:

GTX660 - GUI
GTX Titan - Compute GPU

Source: BMCC 2,5K RAW
Target: h264 1080p export
(SSD1 to SSD2)

1 node, (white balance, light color correction)
Spatial NR - Medium - Chroma Threshold 14.6
Average frame rate: 18-20 fps

if Temporal NR enable - (2, Better, Medium, 0.0, 10.4, 10.7, 0.0)

the export speed drop to 10 fps


The same setting, single AMD 7970, 12-13 fps, and single GTX580, and GTX660+GTX580 similar 12-14 fps.

if Temporal NR enable - (2, Better, Medium, 0.0, 10.4, 10.7, 0.0)

the export speed drop to 6-7 fps


This is better, at least it is not a waste of money...

Ah, this is good to see. The temporal NR is indeed splitting the pack. Might just go for a Titan! Thanks again fec!

Should be a common, benchmark test platform.

Raw, DNxHD, ProRes, files + LUT or .drp files in one package, light to heavy grade setting.

...and then everyone could test :)

There is the Standard Candle but it doesn't compare RAW etc. It does give a standard that everyone compares to though:

Hi Fecxxx, can you try the last round of tests and use 4k Sony raw images with full debayer and a 2k-DCI timeline? Other test parameters the same. You might find the results interesting.

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?
