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

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.

Regards Carsten.

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:

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.

Hello guys,

Wasn't going to upgrade anything in ny hardware for some time, but forgot some time ago I had listed my 2x Titan Xp for sale. Today I got a call from a guy who is interested in buying them - but it's now or never. Considering the rather high price I'm calling for them, this is quite an opportunity. But I have some doubts about what to buy instead...

Given the known cooling issue of NVidia Founder Edition cards stacked one above the other, if I buy 2 of those I'd need to put another card in-between them which would mean I'd never be able to add a third RTX 2080 ti; for this reason I was considering 3x Asus Turbo 2080 Tis as they have the blower cooling design, Unfortunately, they are not available yet. My question to you is this:

Which setup would be likely to give me a better performance (in terms of the best possible balance of my 2990WX CPU vs. GPU power):

1. Two nVidia Founder Edition RTX 2080 Ti cards, each in x16 slot and over-clocked from factory; sounds nice but with my mobo layout and presence of Decklink 2-slot card - no chance for a 3rd GPU or

2. Three Asus Turbo RTX 2080 Ti cards, only 2 in an x16 slots and 1 in an x8 one, and not over-clocked (reference specs)

3. The easiest one from both financial and logistical point of view: just leave my 2x Titan Xp (each in an x16 slot, of course) - and perhaps buy a 3rd (used) one and put it in the remaining x8 slot. The caveat being once Resolve starts using RT Cores & Tensor cores, I won't be able to take advantage of that with my Pascal GPUs...

If you think the best solution would be the Number 1 one above, I'd have my dilemma solved as for not much more money than the guy is willing to pay for my Titans, I'd be able to buy 2 nVidias now. What do you think? Cheers

Piotr

Hi Cartsen,

Good question - I have a 1300 W PSU from Corsair.

Good to see you in this discussion again, because your sensible attitude to hardware configuration in general is what I need exactly. To re-word my previous post, I'd ask two, more general questions:

1. Number of GPU cards: 3 vs. 2 (in the context of the 32-core 2990WX CPU)
Considering that with most (if not all) X399 motherboards we only have two full speed, x16 PCIe 3.0 slots, does adding a 3rd GPU card into the x8 slot improve the overall GPU performance at all (and I'm after improving it very much, as with my 2889WX I often see my current 2 Titan Xp's laboring hard at close to 100% load while the CPU only touches 40-50%)

2. RTX 2080ti models to consider (if the answer to Point 1 makes this one relevant)
- because of the known cooling issue of the Founders Edition nVidia RTX 2080 Ti (and similar) cards, placing 3 such cards in my system is out of question for thermal reasons; but considering the nVidia is over-clocked - and the only other 2080 ti card with the single fan blowing out hot air through the back of the case (the Asus Turbo RTX 2080 Ti) is not - perhaps the overall performance of 2x O.C.-ed nVidias (both in full speed x16 slots) would not be worse than that of 3x not-O.C.ed Asus cards (with one in the x8 speed slot)?

I must admit I'd appreciate your opinion asap, as the potential buyer for my current Titans will only wait by tomorrow... TIA

Hi.

I am sorry, but I am on the way out of my door and will return later.
But my feeling is that I can't recommend to run a 2990WX CPU and 3 huge graphics cards on a 1300 Watt power supply.

But you can make the calculation yourself or I am sure others will do it.

Piotr, with all respect, it has happened several times now in various topics that you have asked a question and that people provide you with answers that you then simply ignore and continue to ask the same question. I wonder why you keep asking questions if you do not do anything with the answers.

I guess you're right, Cary - mea culpa.

It's just that I enjoyed my current system so much I forgot my Titan cards are still listed for sale; the call from potential buyer made me think about upgrading again - and I frankly forgot what consensus has been worked out on the matter (although not quite conclusively) in this very thread.

Oh well - it must be my age, forgetting things, unfortunately :(

Piotr

PS. You will admit, though, that with so many strange results of various tests & benchmarks published (like the x8 being sometimes faster than x16) - my main dilemma "2x overclocked nVidias in x16 slots vs. 3x base specs Asus cards in x16-x8-x16 config" is an interesting one, and deserves some investigation. Also, I'd appreciate an answer to this question: is the heating effect of nVidia's cooling system so strong that even separating two of them with a Decklink card in the x8 slot in-between may lead to overheating the Decklink? These are still valid and open questions...

Hi.

When I look into the power consumption will I begin with the easy part. Newer run a PC power supply to the maximum. Personally I will never run it at more than 70% to 80% of the rated power. So for a 1300 Watt power supply minus 25% will leave 975 Watt for actual consumption.

For the CPU I found a consumption of 343 watt for a 2990WX in this link.

http://www.coolermaster.com/power-supply-calculator/

The 343 watt do I find reasonable. Leaving 627 watt for the Graphics cards and the other components.

And now to the different part of this calculation. When I look into the above calculations and Graphics cards reviews do they all expect you to run games in a SLI setup. But Resolve is not a game and is not using SLI. In resolve all the image processing is done in the CUDA cores and resolve is not using SLI.
I can't find a reasonable estimate of how mush 3x graphics card will consume of power when running Resolve. But for me will 627 Watt, more be 2 than 3 graphics cards.

When I look into the power consumption will I begin with the easy part. Newer run a PC power supply to the maximum. Personally I will never run it at more than 70% to 80% of the rated power. So for a 1300 Watt power supply minus 25% will leave 975 Watt for actual consumption.

For the CPU I found a consumption of 343 watt for a 2990WX in this link.

The 343 watt do I find reasonable. Leaving 627 watt for the Graphics cards and the other components.

Correct - with 3 cards I'm almost at the edge (BTW, a PSU is most efficient here). But I agree that should I decide for 3 cards it's either no O.C. whatsoever (of CPU or GPUs), or upgrading to some 1,500W PSU minimum. I'm not planning to overclock, so would try before upgrading...

I did some research, and here's the info for all of those Resolve users who - like myself - are considering upgrade to 3x RTX 2080 Ti cards without fear of the sub-optimal thermal conditions the two or three fan design cards (like the original nVidia Founders Edition, and most of other manufacturers' models). Here is a list of blower-type cooling cards which don't suffer from this, exhausting the hot air through the back of the computer case:

1. MSI GeForce RTX 2080 Ti SEA HAWK X (https://msi.com/Graphics-card/GeForce-R ... AWK-X.html)
2. Asus Turbo RTX 2080 Ti (https://www.asus.com/Graphics-Cards/TUR ... 080TI-11G/ )
3. ZOTAC GAMING GeForce RTX 2080 Ti Blower (https://www.zotac.com/product/graphics_ ... -ti-blower )

Of course they are not exactly the same in design; the MSI has hybrid cooling where the heat from VRAM and VRM still circulates inside the case, but at least the GPU is water cooled (which not everyone is an enthusiast of; BTW there also is an all-water cooled model from MSI but this one requires a 100% water-cooled PC). Also the other 2 models are not created equal, even though they look almost exactly the same: while Asus have chosen their blower card to not be factory overclocked, the Zotac blower is heavily OCed. Personally, I like the latter's approach - but those cards are going to be rather expensive plus in my case, a PSU would need to be upgraded to at least some 1,500W (which would make the upgrade even more expensive). For that reason, I'll probably end up with 3x Asus Turbo (if I decide to upgrade at all - the alternative in my specific case being the 3rd Titan Xp, if I find a used one cheap enough; I'd still probably need to upgrade my PSU but the 2990WX CPU really calls for 3 GPU cards so this is probably unavoidable some time down the road, anyway).

Anyway, I hope this summary can help some people here :)

Hi Piotr,

I plan on running an RTX 2080 Ti with Resolve Studio once the new Intel Core i9-9900K processors are back in stock and I can purchase one for a new build.

My usual work export encode is RAW 4:1 to HEVC 8-bit (10-bit freezes my system, see signature for specs). Only RAW adjustments and light Temporal Noise Reduction on the timeline. I'll post the results if you're interested, but the new i9 may not be available for some time.

Hi Christopher.

Intel made a mistake when designing the new Core i9-9900K processor. Last year they increased the number of cores of the mainline CPU to 6 and this year to 8. But they forgot to increase the number of PCIe lanes. The i9-9900K CPU still have the same low number of PCIe lanes as the 4 cores CPU used years ago. And can therefore not be recommended for Resolve.

Back in October Intel Announces the X-Series Basin Falls Refresh CPU's manufactured in 14nm++ with up to up to 18 Cores and ships in this November. If you like Intel CPU's, is it a much better choice and I expect it to be included in the new updated Resolve configuration guide BMD is working on.

Until then will I recommend you to read the old Resolve Configuration Guide in this link. Specially the impotence of many PCIe lanes:

TR1920x is cheaper, faster, has more PCIe-lanes, more memory lanes and is available.
Core i9-9900K is a gaming cpu.

If BMD would use the QSV core then the intel CPUs would be super-good for video work -- but at this stage, they don't :-(

Quick Sync Video only helps for decoding/encoding a few select highly compressed formats. It won't help at all for all the other stuff - the actual work - that Resolve does in between. ;)

Since Resolve converts everything internally to 32 bit float RGB, the extensive Resolve pipeline will always have a higher processing requirement than simply piping YUV video into a QSV encoder.

I do believe QSV is implemented in Resolve Studio, at least for h.264/h.265 on a Mac since it uses the macOS decoder/encoder.

Edit: Found confirmation from BMD that h.264/h.265 acceleration using QSV is implemented since v14.2.

(sorry for going off topic)

Can anyone tell me whether the current Resolve version (15.2.2) makes any use of RT cores and Tensor cores on the Turing cards? If so, which functionalities do that?

Thanks,

Piotr

No, FP32 only at the moment.

I'm just finishing tweaking / testing a new workstation with a 2080 Ti (Asus "Turbo" edition -- i.e. blower design). i9 14C, 128GB RAM, all NVMe drives, etc.

I decided to go for the 2080 Ti instead of Titan Xp or 1080 Ti because... well, I don't know, it was Christmas time and I felt like rolling the dice on those Tensor / RTX cores being implemented by BMD to power some kind of new noise reduction or whatever. Who knows.

Anyway, I haven't run strict benchmarks yet but the single 2080 Ti feels roughly as quick as the pair of 1080 Tis in another workstation I use (with otherwise nearly identical parts), maybe quicker in some places like scrubbing (maybe due to the faster VRAM?). This is just in regular tasks like editing R3Ds, grading with light SNR / TNR, source caching, etc.

I find the Puget or Standard Candle-style synthetic benchmarks to be a little misleading, I'm rarely bottlenecked by single clip performance (except when doing beauty work), it's often a mixture of different things slamming the card simultaneously that cause performance bottlenecks.

VRAM is obviously still an issue with lots of nodes or beauty work in 4K -- I was really hoping they would bump the Ti to 12GB this generation, but the RTX Titan is too expensive for what I need to do so I guess the 2080 Ti is still the single-GPU sweet spot (though I notice that sweet spot keeps getting more expensive every generation).

I will run some standard tests if people are interested, but overall I am satisfied with performance. Would have been more satisfied at ~$200 lower MSRP, but whatever, over the lifespan of the card (fingers crossed) it works out to a pretty small fraction of my CODB.

Oh, only thing to say about the Asus blower card -- it is LOUD. Louder at idle than the Asus blower style 1080 Ti, louder at both idle and load than the 1080 Ti FE, and ludicrously louder than the 980 Ti blower. Minimum noise level at the exhaust is about 40dB at idle.

Hmm...for thermal reasons, I have also been considering buying 3x 2080 ti of the blower type, but only after having succeeded selling my current 2x Titan Xp. I start wondering whether - instead of selling my Titans cheap, and buying the 2080 tis expensive - I should buy a used Titan Xp as my 3rd GPU... As long as RT cores and Tensor cores of Turing cards don't do anything special in Resolve, I guess that with 3x Titan Xp I'd get similar performance to 2x 2080 ti cards - or am I too optimistic?
