What's the best GPU for roop-unleashed price independent and also which would be the best cost/benefit ?

Roop-unleashed is VRAM hungry. The more threads you want to run, the more VRAM you need. In terms of compatibility I'd definitely go with an Nvidia card.
Putting insane datacenter-GPUs like H100 aside, I'd say an RTX A6000 with 48GB VRAM would be my highest, realistic, price independent choice. Price 4-6k.
Cost / benefit I'd go for an RTX 4060 Ti 16GB, you can get them for under 500 bucks. Anything higher and the prices are skyrocketing.

Hi,
is there a comparator which can define how take a conversion by vram ? (benchmark)
example à table:

gpu model - vram - 1 min video - 5 min video - 10 min video
GPU 1 - 16G - 5 - 25 - 250
GPU 2 - 32G - 2 - 10 - 100
GPU 1 - 64G - 1 - 5 - 50
etc....

How long a conversion takes, depends on more than just the graphics card, most of all which enhancer you use and the nature of the video itself. For example (using GPEN enhancer on a 720p target video, RTX3060 12GB, 2 threads):
If the whole time only 1 face is visible in the frame and that's the face to swap, that amounts to ca. 4.5 frames/s. If there are 2 faces to analyze and 1 face to swap, fps drops to somewhere between 3.9 and 4.2 frames/s. At sequences of frames with no faces, it goes up to ca. 120 frames/s. Analyzing and swapping 2 faces, fps drops to ca. 2.2 frames/s. Depending on the target material, my overall fps for a whole video can be between 4.7 fps (was the lowest I think, so almost every frame had the face to swap) and over 15 fps, more than 3 times faster.

So you'd have to use the same video(s) to benchmark, and even that would only give you ballpark for other videos.
There was a short benchmark video on the original roop which people used to compare, but not anymore. Feel free to start a new thread and upload one or several (different lengths) videos for direct comparison, I'm in 😉

Yes of cours,
i wanted to say : a benchmark with a test (1 face, during a specific time then making the test with others GPUs or CPUs to compare the results)
