GPU Acceleration

Kevin-Kierer wrote on 6/24/2022, 8:51 PM

I am thinking of buying a GPU acceleration card. I have never used one of these, so my basic question is if these speed up rendering times when you are rendering your final project. I know they make previewing playback much better, but I just want to speed up my final rendering of the end video master file. Also, does anyone recommend a decent card that works well with VEGAS PRO 19? I believe the NVIDIA is recommended. Any help would be appreciated as I want to make sure I buy the right card. I have a WINDOWS 10 PC & an Intel i7 processor. Thanks.

The RTX 3070 is a reasonably priced, reasonably powerful card to use. Going above that in power will start to yield diminishing returns when comparing price vs. performance in VEGAS alone... you'd spend hundreds more and maybe get 10-20% more power (way over-simplified, some cases you'll get more, but only certain cases). It will speed up renders, but the quality isn't as good as CPU rendering (it's close enough that average joe won't notice a difference). It also speeds up rendering even on the CPU by decoding and aiding in the processing of certain effects.

If you already have an Intel i7 processor with a recent iGPU, you have QSV encoding. It can hold its own with a new NVIDIA card for encoding speed (though if you have an effects-heavy timeline a faster GPU will also help with that).

Here are render benchmarks and you can see differences between different GPUs. You can try it yourself, too!
