Best Buy’s weekend sale takes up to $200 off the pricey iPad Pro (updated)
I shoot video with 2 or 3 cameras and routinely have 3 or 4 over-lapping video streams to render out in addition to titles and over-laying extra video footage. So as to provide relevant test measurements for you, the table results have been normalised to show the number of seconds required to render a second of video.
It renders faster than realtime, and it performs at twice the speed of the Mercury Playback Engine using software CPU rendering only. Premier Pro CC These are interesting results. I would have expected the much more capable Quadro M to out-pace the more modest Quadro K Whether the reason behind this is due to video management, storage, or other issues, is not clear.
What is clear is this. This is, frankly a surprise.

But it means that for the first and second test cases, which apply to most editing situations, the Quadro K is an excellent upgrade for your system. The extreme drop in performance between 2 and 3 concurrent video streams is inexplicable. I cannot explain this performance degradation, but we can give you an idea what it looks like. In the first column, the CPU is almost, but not fully utilized. The CPU usage follows a pattern of small peaks.
Artificial Intelligence Computing Leadership from NVIDIA
The second column is the CPU renderer. Compare this to the first column where the addition of the GPU renders the same video 2. The third column is the CPU utilization while rendering 4 video streams concurrently using the GPU renderer and the fourth column is the same video sequence using the CPU renderer. In the fourth column is the CPU utilization for rendering 4 video streams with still exceptionally slow results.
Unlike the second column, the CPU is not being fully utilized.
I also benchmarked Adobe After Effects. This feature is apparently considered obsolete and is not supported by Adobe.

Render times in After Effects are notoriously inconsistent. Due to this, I ran a 3D logo rendering test 4 times and provide an average result. As with the Premier Pro CC testing, the normalized results represent the number of seconds required to render one second of video. The rendering time for a second of After Effects video can be more than times longer than the rendering time for Premier Pro and the GPU basically doesn't help at all for After Effects.
An After Effects workstation needs extreme computing power. In fact a good After Effects CC workstation needs high performance subsystems like memory and storage, too.
Which NVIDIA Quadro works best for Adobe video?
Just make sure you are up to date with CUDA drivers. Where I work that wont fly with corp standards. Thanks very much for your help, guys. Walter, that chart really helped me in my search to get the most bang for my buck. I ended up going with the GTX which I bought from macvidcards on ebay.
This guy does some declocking and whatnot to make sure the cards work properly with the Mac Pro. When ram previewing a scene, I get screen tearing.
It's not terrible, but is distracting. If I play the same rendered out clip in Quicktime, I don't have this problem, so it must be AE not liking the card because I didn't have these issues with the stock ATI card that came with the Mac Pro. And it occurs on both monitors - so I don't think it could be the DVI converters.
