DVDFab Enlarger AI for Copy CPU vs GPU image quality with Enlarger AI

[Conrado77]

When I am converting a BD to UHD with Enlarger AI, an encoded in x265 is made. So, will better image quality be obtained using the CPU?

I suppose that same answer will be valid for DVD to BD case.

Thanks

CPU produced better images in Ripper for DVD and BD sources, not sure if this is a practical choice for AI due to the time and volume of computations required

Many thanks. In my case I have an i9-10980XE (18 cores / 36 threads). It is a powerfull CPU. With it I can get from 6 to 8 FPS when enlarging BD to UHD. I normally open two instances of DVDFab Enlarger AI because with only one of it the CPU usage is aroung 85%. With two instances working in parallel the CPU usage is 100% constantly.

But, in the future I plan to buy a RTX 3090 24GB. But I am concerned about power consumption. I don't know if the power consumption / performance ratio will be better or worse than for the i9-10980xe. When this CPU is in full load with Enlarger AI it consumes around 175W sustained. And I can get 6 to 8 FPS. But the RTX 3090 consumes much more in full load. nVIDIA says around 350W, which is double that in the case of the i9-10980XE. If I could get a lot more FPS than 8, then it would be worth it. And that's not counting image quality, which I already suspected would be better for CPU than for GPU.

Thanks
