this seems like a topic that would come up often but I couldn’t find much in this forum.
I am currently editing my 16mp RAWs on a Laptop with an old Intel I7 3517U (dual core) and 4GB of RAM with an external 4k monitor and it is too slow for my taste. I also have an old desktop PC with a Phenom II X4 945 and 6GB of DDR2 RAM.
My first question is now: does Darktable use OpenCL so much, that the old desktop PC with a graphics card from the AMD RX line (570 or 580) would speed up considerably (I am looking for ~4x the speed), especially while editing (I don’t care so much how long exporting takes) or do I need to buy a new PC?
Second question: I feel like the RX580 with 8GB of VRAM has a bit of a “top of the line fee” on it’s price and therefore I am considering the RX470 with 8GB of VRAM and the R580 with 4GB of VRAM, which one is the better choice (price is about the same)?
The modules I use most are:
- White balance
- Several instances of the exposure module combined with masks
- Base curve
- Crop and rotate
- Shadows and Highlights
- Color curve
- Color correction
- Chromatic abberation
- Denoise (profiled)
- Lens correction
I have found the Phoronix article, but it didn’t really answer my questions.
Thanks for your thoughts
