This test is about exporting to JPEG from Capture One 20, a very common production task. Exporting to TIF would be a bit slower, due to much greater I/O demands (about a gigabyte per file), and should therefore be done using a very fast SSD when performance is a concern.

Results: Raw file conversion to JPEG — 150-megapixel Phase One IQ4 Raw

Processing lossless-compressed raw Phase One IQ4 raw files is presumably single-threaded for the decompression phase, which would account for the use of 2-3 CPU cores during this test. Everything else appears to done by the GPU when using Capture One 20. That’s good, but what is not so good is that 5 to 6 of 8 CPU cores are idle the entire time. Ideally Capture One would use both the CPU cores and the GPU.

The 2019 MacBook Pro takes 31% longer than the 2019 iMac 5K. If repeatedly exporting large numbers of JPEG is your thing, then the MacBook Pro falls short compared to most other metrics.
