One needs a supercomputer for that!
I tried to “upscayl” a 700x700px image to 2800x2800px on an ordinary pc. The four cores of my cpu were working at 100% each. After some 15 or 20 minutes (not seconds!) a progress indicator appeared: 0,00%. 5 or 10 minutes later it showed still the same: 0%, so I killed the program.
On my pc at least this seems to be a waste of electricity…
Perhaps it works better if I buy an array of those fancy & very expensive nVidia cards that other people use to make bitcoins…
