TL;DR: AMD Radeon RX 6800 & 6800 XT performance in DaVinci Resolve

Outside of a few cases like Fusion, the new AMD Radeon 6800 and 6800 XT are a good amount faster than the older Radeon 5700 XT and Vega 64. In GPU bound tasks like noise reduction and OpenFX, these new cards as much as 83%(!) faster than the 5700 XT. Unfortunately, that isn't enough for them to catch up to the NVIDIA 3000 series cards. The RTX 3070 is less expensive than the 6800 and 6800 XT, yet outperforms them in our GPU Effects tests by a solid 14%. And if you can find an extra $50 to upgrade from the Radeon 6800 XT to the NVIDIA RTX 3080, you will see up to a 70% performance gain by going with NVIDIA.

Introduction

Recently, AMD launched their new Radeon RX 6800 and 6800 XT GPUs and while supply has been especially tight, we have finally managed to get our hands on a pair of cards courtesy of our friend Brian Stroh at BPS Customs. AMD has advertised very large performance gains with these cards, although gaming has been AMD's focus for the Radeon series of cards for the last few generations so we don't quite know what to expect in professional applications like DaVinci Resolve.

This testing is one that has been highly requested due to how much Resolve (especially the paid Studio version) can take advantage of the GPU. In some of our recent testing, we found that AMD lagged behind NVIDIA GPUs by quite a large margin with the Radeon RX 5700 XT not even being able to match the aging GeForce GTX 1080 Ti. It will be interesting to see if NVIDIA is able to maintain their sizable performance lead, or if the new Radeon RX 6800 and 6800 XT GPUs will allow AMD to match or beat NVIDIA in DaVinci Resolve.

DaVinci Resolve Studio GPU Performance Benchmark - AMD Radeon RX 6800 and 6800XT 16GB

If you want to see the full specs for the new Radeon 6800 cards, we recommend checking out AMD's product page for the Radeon RX 6800 and the Radeon RX 6800 XT. But at a glance, here are what we consider to be the most important specs:

VRAM Cores Boost Clock Power MSRP
Radeon 5700X 8GB 2,560 1.9 GHz 225W $399
Radeon Vega 64 8GB 4,096 1.55 GHz 295W $499
RTX 3070 8GB 5,888 1.70 GHz 220W $499
Radeon 6800 16GB 3,840 2.1 GHz 250W $579
Radeon 6800 XT 16GB 4,608 2.25 GHz 300W $649
RTX 3080 10GB 8,704 1.71 GHz 320W $699
RTX 3090 24GB 10,496 1.73 GHz 350W $1,499

While specs rarely line up with real-world performance, it is nice to see AMD including 16GB of VRAM on the new 6800 cards since especially for DaVinci Resolve, the amount of VRAM you have can be critically important. Most of the GPUs you would use for Resolve these days have 8GB of VRAM which is plenty for most 4K timelines, but having 16GB of VRAM should allow for 6K timelines to be edited with little problem.

Unfortunately, even 16GB is not quite enough for 8K timelines. For that, we typically find that you want a GPU with at least 20GB of VRAM which largely limits you to the RTX 3090 24GB or workstation-class cards like Quadro and Radeon Pro. Still, the extra VRAM will be useful for those that tend to use multiple noise reduction nodes, a lot of OpenFX, and complicated grading node structures on 4K/6K timelines.

From a pricing standpoint, these cards are right in between the NVIDIA RTX 3070 and 3080 - although currently, supply is so poor that you will be lucky to find a card for anywhere near the MSRP. However, we typically use the MSRP as a baseline for price in order to rule out fluctuations due to different brands, sales, and scarcity. This means that from a performance perspective, we will be primarily looking to see if these cards are able to out-perform the RTX 3070 and whether or not they can beat the more expensive RTX 3080.

Test Setup

Listed below is the specifications of the system we will be using for our testing:

To test each GPU, we will be using the fastest platform currently available for DaVinci Resolve - most notably the AMD Threadripper 3970X. Since Resolve can utilize the CPU heavily in some workloads, this should minimize the impact of the processor and allow each GPU to perform at their fullest potential.

For the testing itself, we will be using the 0.92 version of our PugetBench for DaVinci Resolve benchmark. If you wish to run our benchmark yourself, you can download the benchmark and compare your results to thousands of user-submitted results in our PugetBench database.

We will be using the "Extended" preset that includes both 4K, 8K media as well as specific GPU Effects and Fusion tests. Using 8K media with many of the cards we are testing is actually not a good idea due to the "out of GPU memory" errors you would likely encounter, but our benchmark does not load the Resolve UI which means that the VRAM load is much lower; allowing GPUs with just 8GB of VRAM to successfully complete the 8K tests.

One thing to note is that due to the rolling GPU launches from NVIDIA and AMD, we will be re-using many of the results from our
DaVinci Resolve Studio - NVIDIA GeForce RTX 3070, 3080 & 3090 Performance article. There actually has not been a non-beta update to Resolve since that original article, but newer Windows updates may slightly affect performance with these newer cards. When the Radeon RX 6900 (XT) launches later this month - and we manage to get our hands on one - we plan to re-do all our GPU testing to ensure the results are as accurate as possible.

Raw Benchmark Results

While we are going to go through our analysis of the testing in the next section, we always like to provide the raw results for those that want to dig into the details. If there is a specific task you tend to perform in your workflow, examining the raw results is going to be much more applicable than our more general analysis.

AMD Radeon RX 6800 XT DaVinci Resolve Studio GPU Performance Benchmark

Overall DaVinci Resolve Performance Analysis

While many reviewers like to solely look at things like temporal noise reduction (often to an unrealistic degree) or OpenFX that heavily utilize the GPU, we first want to start off by looking at the overall performance we saw from our DaVinci Resolve benchmark with each GPU in order to show what most users would likely experience in their day-to-day work.

Looking at the Overall Extended Score, the new AMD Radeon RX 6800 and 6800 XT certainly do better than the Radeon RX 5700 XT and Vega 64, but still fall behind NVIDIA's latest 3000-series cards. Even the less expensive GeForce RTX 3070 manages to best the Radeon RX 6800 XT by a solid 10% or the Radeon RX 6800 by an even larger 14%. And if you have a slightly bigger budget, the RTX 3080 is 21% and 25% faster than the 6800 XT and 6800 respectively.

Compared to the older AMD Radeon cards, the 6800 is about 9% faster than the Vega 64 while the 6800 XT extends that performance gain to just under 13%. The 6800 and 6800 XT do have more VRAM than the Vega 64 and 5700 XT, but from a straight performance standpoint, this isn't quite as impressive as what we saw with NVIDIA's 3000 series over their previous generation 2000 series.

One odd thing we found is that the performance in the Fusion tab (the last chart above) with the new 6800 and 6800 XT is not all that great. The 6800 and 6800 XT are slightly faster than the older 5700 XT, but the Vega 64 is about 6% faster than the Radeon 6800 XT. It is also a bit strange that AMD in general gives less performance in Fusion than NVIDIA since most of our Fusion comps are largely CPU limited. There are some GPU effects in them, however, which apparently is enough for NVIDIA to take a solid lead even here.

Bear in mind that this looking at the Overall Extended Score which measures the performance in all of our tests - including a number that can be CPU bound. To get a better idea of the maximum performance difference between these cards, we should hone in on the "GPU Effects" portion of our benchmark which looks at tasks like TNR and various GPU-accelerated OpenFX.

GPU Score Analysis

DaVinci Resolve Studio GPU OpenFX Noise Reduction benchmark performance AMD Radeon RX 6800 XT

The GPU effects portion of our benchmarks looks at the performance of individual GPU-accelerated effects such as temporal noise reduction, film grain, lens blur, optical flow, face refinement, and more. In our testing, these effects easily show the largest benefit from having a powerful GPU, which means that they should give us the best look at the maximum performance gain you may encounter from each of the GPUs we are testing.

Unfortunately, while the new Radeon 6800 and 6800 XT are a solid 33-41% faster than the Vega 64 - and an even more impressive 72-83% faster than the 5700 XT - they still can't quite catch up to the NVIDIA 3000 series cards. In fact, the RTX 3070 is again a good amount faster than the 6800 and 6800 XT, beating those cards by 14% and 21% respectively.

And if you want to compare the Radeon 6800 XT to the slightly more expensive RTX 3080, NVIDIA takes almost a 70% performance lead compared to the $50 less expensive Radeon 6800 XT.

How well does the AMD Radeon RX 6800 and 6800 XT perform in DaVinci Resolve Studio?

Outside of a few cases like Fusion, the new AMD Radeon 6800 and 6800 XT are a good amount faster than the older Radeon 5700 XT and Vega 64. In especially GPU bound tasks like noise reduction and OpenFX, these new cards as much as 83%(!) faster than the 5700 XT. Unfortunately, while that is a massive performance gain, it isn't enough for them to catch up to the NVIDIA 3000 series cards. The RTX 3070 is less expensive than the 6800 and 6800 XT, yet outperforms them in our GPU Effects tests by a solid 14%. And if you can find an extra $50 to upgrade from the Radeon 6800 XT to the NVIDIA RTX 3080, you will see up to a 70% performance gain by going with NVIDIA.

The only time that these cards would make sense to use for DaVinci Resolve is if you wanted to be able to edit 6K timelines but cannot afford the (significantly) more powerful NVIDIA GeForce RTX 3090 24GB. Having 16GB of VRAM on a sub-$1000 card is very nice, although 6K editing has fallen out of style a bit in favor of 8K - and 16GB is not quite enough for most 8K timelines in Resolve. For that, you ideally want to have at least 20GB of VRAM which will limit you to the GeForce RTX 3090 24GB or a workstation-class card like Quadro or Radeon Pro.

Overall, AMD is heading in the right direction with the 6800 and 6800 XT, but just like we saw in many Adobe applications, even the impressive gains they are showing over the 5700 XT just isn't enough for them to catch up to NVIDIA.

As always, keep in mind that these results are strictly for DaVinci Resolve. If you have performance concerns for other applications in your workflow, we highly recommend checking out our Hardware Articles (you can filter by "Video Card") for the latest information on how a range of applications perform with the new AMD Radeon 6000 series GPUs, as well as with different CPUs and other hardware.

In the 8K testings the 6800xt performs equal with a 3090 in two tasks:
- 8K Media RED to H.264 (4K Timeline)
- 8K Media RED to DNxHR HQ (4K Timeline)
and beats the 3090 in:
- 8K Media RED to H.264
- 8K Media RED to DNxHR HQ
while it looses by a lot in other 8K tasks.I mainly look at the 8k results as I use 8k media.
So I would consider, that depending on what 8k Media someone uses, he can go absolutely with a 6800xt. My Problem is, that I have nothing to compare with my files,
I can only see, that in general GPU1 is better than GPU2. But because I use only 8k Canon R5 RAW files, I have no Idea if 3080 is better for this Filetype. So I ordered a 3080 and a 6800xt to find out what will perform better for my specific files and after the finding, I will sell one of them.
In the puget testing I miss also the separation of playback and rendering with a 4k and 8k Timeline.
I will replace a 1080ti on a 1950x threadripper (extended overall score 1025) with a 5900x CPU and one GPU from the 6800xt / 3080.In the puget davinci Benchmarks, when my motherboard resets the 4x16 GB RAM to 2133 MHz the score is 170 less than what I get with the RAM set to 3200MHz. While this is a big difference in the benchmark, I see almost no difference in the playback speed of DR 17 Studio version and only a small benefit in the rendering times. So I can't calculate if the new system will bring me a playbackspeed of 24 fps fpr my R5 8K RAW-files. Before the Update I only get 13fps playback in a 4k timeline and I am affraid, that the update will not give me the hoped playbackspeed (without using proxies).
As an Idea, I guess it would be easy for you to implement a separate Test in your benchmarcs to test the playbackspeed of all the kind of Userfiles (supported by the tested software). The rest would be like a short version of your existing benchmarcs. Then someone like me could test a R5 8K RAW file or whatever Videofile he wants, the Benchmark would read the Metadata and test just the playbackspeed in the used Software with the used Hardware and everyone could search for his specific files to see what software and what hardware performs well for his fileformat.
Thank you for the good comparsions you make here :-)

Interesting... I think I'll hold on to my Radeon VII.

Posted on 2020-12-03 15:31:10

same here am hoping the RTX Titan Ampere is 32GB VRAM that would be fantastic even at £2500 it would be great also we don't know if NVIDIA will make it 32 GB or 48GB source leaks are pointing towards 48GB only time will tell because I believe this will be the best 8K GPU card to get. and that what I would suggest 8K content editors to get. it s priced at £3000 - £3500 it will a steal and a great investment. for a very long time if it is fast and able to handle 8K RED files in a multi stream.

AMD is yet to release it Professional line for GPU and we don't know how well that will stack against the RTX Titan or even the RTX3090 and no idea on what VRAM we could possibly get my guess may 24GB since there Mi100 is only 32GB

I had a Radeon VII before 3090 with Dell 8K monitor.
If AMD puts HBM3 memory or something with >1TB/s bandwidth they are in the game again probably.

Also drivers can make a large difference here and I would think enabling SAM if you are running an AMD platform might be interesting to test.

Hello, I am trying to benchmark Davinci Resolve 17 on my 6900XT and am getting error. Any ideas how I might remedy this? The benchmark woks fine on other cards. I see you have posted 6800XT benchmark, have you guys had a chance to test with 6900XT yet?

Thanks!

Refer to image for error. https://uploads.disquscdn.c...

That is a Resolve error, so likely nothing having to do directly with our benchmark. We actually haven't tested the 6900 XT yet, so I can't tell you if there is just lacking driver support, or if there is an actual hardware/software issue with your system. That said, Resolve 17 is still in beta and I have heard a ton of people complaining about bugs. Wouldn't surprise me if this is something that will just get fixed in an upcoming update.
