Thanks, Misha.

What is lacking in this review is GPU scaling of 2x RTX 2080 Ti vs 2x Titan Xp, with the 2990WX. Anyone seen such info?

Well it's kind of crap because of the cooling lay-out https://www.pugetsystems.com/labs/articles/NVIDIA-Dual-Fan-GeForce-RTX-Coolers-Ruining-Multi-GPU-Performance-1239/.

And it still only has 8 or 11(ti) GByte of VRAM so it's still crap when you use a lot of effects in Resolve.
Someone doing a lot of 8k (and 12 and 16k these days) bought 2 quadro P6000's (with 24GB of slow VRAM 432GB/s costing $5000 each) because of this.

Well - on my X399 mobo, I'd put them into the 1st and the 3rd x16 slots, with plenty of space in between them (this is BTW a setting recommended by the mobo maker), and use the middle (2nd) x16@x8 slot for my Decklink. Would you say it would help, or I would fry my precious Decklink?

The upgrade is not worth it looking at your current GPU's. Your current GPU's are blower-style so these will work pretty well. Don't buy into a hype. End of this year beginning of next year the 7nm GPU's will come out and will give a serious speed-boost.

Even with the 2990WX I have bought for my dream machine? I'm afraid my Titan Xp GPUs might become a bottleneck with that CPU power - with my current 8-core i7, you'd probably be right....

You either have enough GPU power to do the grade you want with full playback, or you don't. Two Titan Xp is already more power than almost any of the Resolve forum users has.

I have yet to see how they work with the 2990WX, Jack :)
The 2080RTX - in the review Misha linked to - is said to be 25% faster than Titan Xp. But there is also the aspect of being future proof which is even more important to me, as this is going to be the very last machine in my lifetime. They say Blackmagic has already announced that they will be using Tensor cores and RT cores, which will widen the efficiency difference between these cards even more. Not to mention that at some point of time, BMD may drop Pascal support altogether, staying with Turing and whatever comes next - and I'm hosed...

Hi.

It will be very difficult to be future proof, specially in the next 3 years due to the following reasons.

First let us take this from nVidea, with the heading 'World’s Top Graphics Software Companies Are Already Adopting NVIDIA RTX Capabilities.'

Quote: 'Blackmagic DaVinci Resolve: World’s most popular color-grading application, using Turing Tensor Cores in Resolve 15 to accelerate AI inferencing for graphics enhancement.'

From: https://blogs.nvidia.com/blog/2018/08/1 ... y-support/

We already know from nVideas Tom Petersen, that the Tensor cores are exposed to to CUDA. But we don't know how far BMD is?
Its it valid for all Resolves ver 15? Or from what version.
What functions will use Tensor cores? Will The OpenCL versions have the same functions, but just slower?
There is a lot of unanswered questens?
If BMD is not in a position where there can answer all the questens. Will I suggest they give us a hint in the next Resolve 15 configuration guide. What to buy?

I don't know if the rumors for new 7nmGraphics Cards is for nVidea or AMD Cards. Personally I will not expect a new Graphics line from nVidea before at least this time next year, as they just begin to deliver the RTX 2080/Ti's. And I expect AMD to do what they did last time. VEGA was a side product from the Graphics Card AMD made for Apple. And I expect NAVI will also be a side product for the next Sony PS5, that first is expected to the end of 2019. So I am sorry, but I can't see any new Graphics Card Line for Gamers in early 2019.

But what we also must not forget, is the new PCIe specifications PCIe 4.0 and PCIe 5.0. The PCIe 4.0 specification have been delayed several times and is very late. And PCIe 5.0 is on schedule. So it is not expected that PCIe 4.0 to be long lived. The PCIe 4.0 Final specification was published in 2017 and the final PCIe 5.0 specification is on schedule for 2019. It will then normally take two additional years before we will see motherboards and graphics cards with it.

https://www.anandtech.com/show/11967/pc ... ie-40-spec

I don't know often you upgrade your Graphics cards?
But I hope most of you, will go from PCIe 3.0 graphics cards and direct up to PCIe 5.0 Graphics cards. And of cause also motherboards.

Regards Carsten.

I think you'll have to switch from your FS7 to 8K RED or similar to challenge your upcoming Threadripper system.

With regard to futureproofing, don't worry too much about that. In another 2-3 years, there will be bigger and badder CPUs than 2990WX, there will be PCIe 4.0/5.0 parts available, there will be faster and denser NVMe drives, and so on. At some point you have to buy what's available in the present, or you will never have a computer to begin with :D

Not only new PCI standards have been delayed several times, but 7nm production too. We are nearing an edge of such technology. Future proofing has never been more difficult, I’m afraid.
Be pragmatic and get what is doing the job today.

Gentlemen - while I value your opinions very highly, please don't forget I had a short opportunity of testing my 2x Titan Xp GPUs, and saw them laboring at 100% while still not providing full fps playback of my typical timeline/effects... And this was happening while my just 8-core CPU only used less than 30% load... With 32-core CPU, I really need hell of a lot GPU power!

Plus - I admit - I'm a perfectionist and suffer from OCD :)

TitanV has around the same speed as the RTX2080ti and also gets crippled by to much data

Image

Spend your money wise, next years GPU's will show a much larger increase in speed than this years over priced under(memory) powered GPU's.
Vega 20 is rumored to have 21 TFlops, 32 GByte and more than 1.2 TByte/s memory bandwidth.
Just wait a year, TitanX(p) is not far behind RTX2080ti.

Great discussion, I am trying to decide whether to buy the latest card or wait til next year. Since my single 1080ti is working well with Resolve 15 I am thinking of waiting to see what next year brings.

But that might change when I get a new camera that does 4k/60.

Just get another 1080ti for around $700.

@piotr

You really need to tell us what your source is, what you are doing to it, and what your timeline/monitoring resolution is. Just giving us what your cpu and gpus are a waste of time for everyone!


Take a look at the Puget benchmarks, as soon as you add TNR you aren't going to get real time playback. 3 1080 Tis still only get you to 27 fps on 4k DNxHR HQ. As you soon as you start talking about raw frame rates start dropping even further.

Even a Titan V can't keep up when you add TNR.

OK guys - it took a long time (partially due to my illness), but my new Resolve machine is up and running for specifications see my signature).

The Threadripper's 32 cores' CPU power balances with my 2x Titan Xp GPU power better than I expected - yet it's still in my plans to replace the latter with RTX 2080 Ti... My big question now is whether to only use 2x such cards (each in the PCIe 3.0 x16@16 slots), or add one more which would need to be installed in the only remaining PCIe 3.0 x16 slot, which only works as x8 speed). Relevant comments welcome :)

Hi.

The RTX 2080 Ti is only slightly faster than the TITAN Xp, RTX 2080 is slightly faster than the GTX 1080 Ti and RTX 2070 is slightly faster than the GTX 1080.

NVIDIA TITAN Xp
GPU Architecture Pascal
Frame Buffer 12 GB GDDR5X
Memory Speed 11.4 Gbps
Boost Clock 1582 MHz
CUDA Cores 3840
Total B/W 547.7 GB/s
12.1 TFLOPs

RTX 2080 Ti
GPU Architecture Turing
Frame Buffer 11 GB GDDR6
Memory Speed 14 Gbps
Boost Clock 1545 MHz
CUDA Cores 4352
Total B/W 616 GB/s
13.4 TFLOPs

I don't know why nVidea makes this changes in the model lines. May be some smart marketing people be live that game customers will then buy a more expensive Graphics card. So I more see you questen, if we will recommend you to buy the Turing version instead of your current Pascal version in the same price range. The answer must be no.

I have NOT seen any rumors of a Turing TITAN Yet. But if/when it arrives can you consider it, if the price is reasonable. But I will like to a link to a post where Rohit Gupta from Blackmagic wrote:
'I would go with a single fast GPU with lots of VRAM vs two GPUs which are slower and lesser RAM. You get lots of efficiencies by running the display and compute on a single GPU, especially for editing.'

From: viewtopic.php?f=21&t=80105

We have in the last generations seen less advantages of multi GPU's and better Single GPU performance. I expect that will continue.

Personally I expect the new RTX 2080 Ti to be short lived. It deliver known performance for the previous Graphics Cards price and some future promises. If this promises don't live up to the the games expectations will the sales drop and nVidea will come with the next generation.

In the next years will we see a lot of changes in the hardware. PCI Express 4.0, 7nm and the similar 10nm and then PCI Express 5.0. So I can only recommend you to upgrade, if you really need the performance of a new graphics card now. If you buy one each time the manufacturer launch a new card, will you soon end up with a lot of unused Graphics Cards.

Hi Carsten,

Thanks for your precious input - but frankly, with hardware there will always be something new around the corner; if I waited I'd have never bought anything. My current system works very well indeed - and if I still consider replacing my Titan Xp GPUs with the RTX 2080 Ti is only because:

- my cards can be considered "as new"; after couple of moths their resale value will drop significantly
- 25% faster is only a part of the story; I'd like to be ready when Resolve offers advantages only available with Turing architecture (and more specifically, its Tensor cores and RT cores)

So I'd love all of you guys to read my question like this: not having a 3rd full speed (16x) PCIe slot, would the 3rd GPU (regardless of its architecture - be it the current Pascal, or Turing if I decide to replace my Titan Xps with RTX 2080 Ti) actually further increase the GPU performance as a whole vs just 2 cards, each in a full speed x16 PCIe slot? What's people's experience with this? TIA

Not a programmer, but it may ned up that Tensor cores and RT cores are about useless for Resolve, so don't count on them so much.
On the day when Resolve may uses them (if they can be used well) you will have new cards with 3x more powerful Tensor cores and RT cores, so maybe should stop thinking this way.

Andrew, I'm handling it quite reasonably, I guess: set myself a rather high, minimum price point I will NOT sell away my Titans cheaper than; it serves the purpose of filtering out any offers below it.

Differences related to Pascal vs Turing architecture (and so the potential use of Tensor and RT cores) aside for the sake of my main point (which nobody's even tried to address yet) - will the GPU performance suffer a serious hit due to the 3rd card in an x8 PCIe slot rather than a full x16 one?

Bold statement, Carry!

Looking here (https://www.pugetsystems.com/labs/artic ... n-Xp-1060/), the colot torture test cleanly shows the scalability of GPU is quite different on Threadripper vs. Intel:

1-4 GPU scalability with Intel vs. AMD Threadripper.jpg

This is of course "just" the 16-core TR, but still... Go figure.

The RT cores might be useful for Fusion, since they implement hardware raycasting and are therefore potentially useful for 3D rendering. Potentially -- it would most likely require a significant update to the rendering engine, and I don't know whether or not that's a direction that BMD plans on heading in.

On the day when Resolve may uses them (if they can be used well) you will have new cards with 3x more powerful Tensor cores and RT cores, so maybe should stop thinking this way.


There's already some new hardware in the Turing GPUs that Resolve isn't using yet, since Turing is brand spanking new... for things like wavelet decoding. No one's using that yet, though I know that at least one company is working on taking advantage of it.
