And that is the problem or impossible, because I want to buy new components, which I don’t own at the moment.
I can compare my Beelink Ser 6 Max Ryzen 7 7735HS (no opencl probably, rusticl not tried) with my Ryzen 7 3700X and GeForce GTX 1660-
The minipc takes about 12sec while the GTX 1660 takes about 5sec.
I want to get an idea, how fast a graphics adapter in a midtower-pc of 2025 can be and how fast a minipc using opencl can be with darktable.
GPU benchmarks in darktable shows very old graphy adapters, that doesn’t help me.
