ok, stand corrected. Thanks for trying it.EVGA 2080Ti FTW3 seems to be able to handle it. Just encoded a 3 minute 4K30P video using H265 with 'medium' compression in Handbrake in 1:40 seconds.
Most likely I'm not doing it right.
so now you have a gpu which is as large? as the r5 with 2? fans and a tdp of around 280w which can do real-time 30p and by your timings do almost 60p (but not 120p nor 8k) No idea on the quality of your 30p vs r5.
pretty impressive what the r5 is doing in such a tiny space.
doesnt detract away from what people are saying about the overheating, just gives insight into the challenges and trade offs.
