Graphics Card Selection for Premiere and AfterEffects (Direct X vs CUDA Cores)

I'm in the process of buying a video card for my computer to aid in video editing and I wanted to know if PR and AE support Direct X - or - if the video cards have to be CUDA cards to be supported. Please advise.

To support Windows you need DirectX.  Both nVidia and AMD support DirectX

To get GPU Acceleration in Adobe Premiere the card must have either CUDA or OpenCL.  nVidia cards with CUDA are better than AMD ATI cards with OpenCL.  I just received PPBM results from the new 16-core AMD Threadripper CPU system tested with one of the latest cards from each vendor.  The GTX 1080 Ti was far the best over the new AMD Radeon Vega Frontier Edition, and from the scoring on these tests I can tell you that you do not need a GTX 1080 TI to equal the results of the Vega card, it could safely be done with a GTX 1070 or maybe even a GTX 1060 6GB card.

I usually shoot video in 2k or 4k and downscale to 2k or 1080p with colour correction etc so my card is used all the time.
The CPU usages hovers around 60% - 70% with the GPU usage at 90% - 98%.

I am currently looking to upgrade from the 750ti and searching for the best path.

Also Bill thank you very much for all the work you do here and all the testing. I really appreciate it and I'm sure lots of others do to.

Samtastico,

Your GPU can use some improvement, judging by the CPU vs GPU utilisation results. Unfortunately, the GPU that would have given a worthwhile enough improvement over your current GTX 750 Ti - the GTX 1060 6GB - now costs at least double what it should be due to the current cryptocurrency mining craze. I was fortunate enough to purchase one back in Spring of 2017 for the $250 USD plus tax, because most places now charge $500 to $600 USD for one. And performance-wise, any of the "affordable" current GPUs are a substantial downgrade from your GTX 750 Ti, while the GTX 1050 (the current GPU that's closest in performance to the GTX 750 Ti), in your situation, costs way too much money for only a marginal at best performance increase.

Hence, I am recommending that you stick with your current GTX 750 Ti until the prices come down to sanity levels.

Since it seems for most users we have got to the point where the increase in GPU does not necessarily relate to rendering performance.   Does anyone know Of a comprehensive list of cards that shows in relation to each other the expected increase so one can make an educated choice on a card that will fit their budget.

The only list I have found so far is a CUDA score list but by the sounds of it, it might not be the best indicator

Here is a more comprehensive list.

Looks like most of the 780ti, 980ti etc have good bandwidth, speed and CUDA scores

CUDA cores are not the only thing, memory clock, memory bandwidth aree also significant.  as you can see from my GPU testing using Premiere Pro.

It does not help, but certainly adds a lot of confusion but different vendors and different programs have at least 3 different ways of specifying memory clock speed
