Local Video Generation Too Slow? RTX 5090 Takes Minutes, B200 Takes 1 Minute
dtdisapointingresult · reddit · 2026-08-14
Using MiniMax H3 as an example, the author highlights the computational dilemma of local video generation: rendering an 8-second 540p video takes 15 minutes on an RTX 5080. Extrapolating from these figures, even an SOTA B200 GPU would require about a minute. Given doubling GPU prices and marginal performance gains in next-gen hardware, the author argues home users won't see fast, convenient local video generation anytime soon.
