I’m looking for a new laptop and stumbled over the question, if I really need a dedicated graphics card. By far the most laptops in my desired price range are shipped with Intel UHD 620, some use AMD Vega 8/10, NVIDIA MX150/250, 1050 or something like that. My current laptop (XPS 15) has a 540M and is about 6 years old.
Since I don’t play any demanding games on my laptop the only thing that came in my mind, why a dedicated GPU would make sense, was darktable. So there are mainly two questions that arise:
Apparently Intel (and AMD?) GPUs are blacklisted for OpenCL in darktable, can someone confirm or disprove, that with an Intel GPU OpenCL does not work?
Apart from that, what are the advantages of using a dedicated GPU with darktable, how much is the speed gain? Is there anything else that might be relevant?
Thanks in advance!
