Premiere Pro CC 2018 Workstation GPU Performance

Introduction

For those that need a workstation card for Premiere Pro, we wanted to determine how various cards from NVIDIA's Quadro and AMD's Radeon Pro lines perform. Information on our testing process can be found in the Test Hardware & Methodology section or you can skip right to the Conclusion. If you are more interested in the performance of NVIDIA's GeForce and Titan line, we also have a similar article available that covers various consumer oriented cards: Premiere Pro CC 2018 GPU Performance: NVIDIA Titan V 12GB.

Test Hardware & Methodology

To see how modern workstation graphics cards compare in Premiere Pro, we opted to combine a number of different GPUs with the Intel Core i9 7940X CPU which is currently the fastest all-around CPU for Premiere Pro. Our full test platform consists of the following hardware:

The workstation GPUs we will be testing includes a number of cards from the NVIDIA's Quadro and AMD Radeon Pro line as well as the NVIDIA Titan V to act as a comparison point:

The footage used in our testing is shown below with links to where you can download it yourself:

While this is by no means every codec available, we do feel that this covers a much wider range than our previous testing. In the future we may cut down on the number of RED clips and replace then with something like XAVC-S or AVCHD but we really wanted to see how the different compression levels impact performance.

Our testing was done with three different timelines to simulate different types of workloads.

To be clear, these test sequences are not anything fancy and frankly don't end up with a very nice final product since they are simply copies of the same clip over and over. However, if you wish to replicate our testing we have all the project files and export presets available for download. You should be able to replicate any of our tests by downloading the clips from the original source, making 10 copies of each clip, and re-linking the media in the appropriate project file. Export time was simply recorded from when the "Export" button was clicked until the export completed. Live playback FPS (frames per second) was measured based the number of dropped frames relative to the total number of frames in the sequence. For example, if we dropped 100 frames in the 4K ProRes 422 HQ "Basic" timeline (which has 579 frames), that means we rendered a total of 479 frames over 24 seconds for an overall result of ~20 FPS. For ease of comparison, we also have the raw number of dropped frames listed in the Live Playback section.

Live Playback

Live playback performance is a challenge to accurately test since performance depends not only on the codec and resolution of your media, but also the playback resolution (full, half, quarter, etc.) and the effects you have applied. Since this is the first full round of testing with our new benchmark process, we decided to go all out and benchmark all our test media with not only three different timelines, but also at full, half, and quarter playback resolution. For more information on each test media and timeline, check out the Test Hardware & Methodology section.

Individual Avg. FPS Results

[+] Show Raw Dropped Frame Results

Due to the huge amount of data gathered in our testing (over 800 different data points in total!), we are not going to go through everything point by point. If we tested a codec you typically work with, we highly recommend looking at the "Individual Avg. FPS Results" charts or the raw Dropped Frame results by clicking on the "Show Raw Dropped Frames Results" link. However, for a general overview of how each GPU performed we decided to average the results relative to the Quadro P5000 video card.

Likely, the first thing you may notice is that the Radeon Pro WX 9100 did not do particularly well in this test. The overall average chart is a bit shewed since the largest area it struggled was with RED footage, but even in general the performance was fairly lackluster once effects like cross dissolves and Lumetri Color was applied to the timeline. One thing we do want to point out is that our testing is done with the cache and system RAM completely cleared in order to replicate what the performance would be like if you were working on a fresh timeline. What was interesting was that while the Radeon Pro WX 9100 gave overall poor performance in this "first run" situation, if you played the same clip multiple times the performance was much higher. For example, in the RED 8K 9:1 testing at full res with no effects, we only received about 9 FPS in our test. However, if we played the clips a second or third time, it jumped right up to around 25 FPS. The NVIDIA cards do exhibit similar behavior, but it was never as dramatic as what we saw with the Radeon Pro WX 9100.

Something else that we fist discussed in our Premiere Pro CC 2018 Titan V article (which included various Titan and GeForce cards) is that the lower the playback resolution, the less the GPU model impacts performance. Of course, at a certain point the GPU doesn't matter since you can't get any better than 0 dropped frames, but even when we were dropping a decent number of frames the difference between the Quadro P4000 and the Quadro GP100 at half or quarter resolution was often less than 1-2 FPS. This suggests that at lower playback resolutions, the GPU takes a back seat to the CPU in terms of importance. This is a very significant finding since with 6K and 8K footage you will likely be dropping to half or quarter playback resolution if you add a decent number of effects in order to maintain near real-time playback. If this is something you will be doing regularly, then you are likely better off with a slightly lower end GPU and spending the cost savings on a more powerful CPU if possible.

At full res playback, however, there is definitely a very distinct difference in performance between each GPU. With 4K footage it may not be terribly noticeable unless you use a lot of accelerated effects, but with 6K and especially 8K footage the difference can be pretty dramatic. At those resolutions we would highly recommend the Quadro P5000 as a starting point and upgrading to the P6000 or even the GP100 depending on the kind of performance you need.

Exporting

Exporting is one of the biggest single time sinks for a Premiere Pro user and is often the go-to metric for measuring performance. For this test, we will be examining 4K, 6K, and 8K projects using all the different codecs listed in the Test Hardware & Methodology section. Added up, this works out to just over 40 different individual tests for each GPU resulting in just under 250 total data points.

Individual Export Time Results

Due to the amount of data we collected during our testing, we once again decided to compile the results into a single overall average relative to the Quadro P5000 video card. If you are primarily concerned about just one of the codecs or resolutions we tested, we highly recommend checking out the individual results – just click on any of the thumbnails to view the full-sized chart.

With that said, from an overall perspective we saw a small but noticeable performance improvement as we used more and more powerful (and expensive) GPUs. However, keep in mind that this is just an overall average. In some cases – like when using ARRIRAW footage or when exporting 8K projects to 8K H.265 – all the GPUs performed roughly the same. Other times, there is a decent (but not vast) difference in performance between the lower and higher-end cards.

Conclusion

Looking at just Live Playback at full resolution with the "Heavy Effects" timeline and overall Exporting performance, we get a pretty good idea about how the various workstation cards stack up. Really, the only surprise was the poor performance of the AMD Radeon Pro WX 9100. Otherwise, there is a small – but noticeable – increase in performance as you use higher and higher end cards.

If your workflow requires the use of a workstation GPU, the card you should get really depends on your workflow. If you work with 4K footage and don't use many effects, the Quadro P4000 should be more than adequate. If you tend to use Lumetri Color, Cross Dissolve, or other GPU accelerated effects, however, we would highly recommend starting with the Quadro P5000.

Similarly, if you work with 6K or 8K footage then the Quadro P5000 is really the entry card you should aim for. The more effects you utilize, however, the more benefit you will see from upgrading to a Quadro P6000 or even a Quadro GP100. Keep in mind, however, that even though the Quadro GP100 gives terrific performance in Premiere Pro, it is actually about on par with the GeForce GTX 1080 Ti. So while it is a great card, unless you really need the 10-bit display support you can save somewhere around $6,000 by using the GTX 1080 Ti instead.
