Raw file conversion to JPEG — Nikon D850 45-megapixel NEF lossless compressed
Nikon D850 raw files are compressed in a way that reduces parallelism (processing harder to use multiple cores on each raw file).
The Mac Studio M1 Ultra processes 45-megapixel Nikon D850 raw files in just under one second each.
Adobe has improved raw file conversion considerably since early 2022. That is evident in the very slow results from the 2019 iMac 5K running Photoshop CC 2021 v22.5.8.
