The iMac Pro’s performance cannot be fully written off in 2024, especially regarding video editing. It manages 4K 10-bit footage quite well and has reasonable export times. The newer models with M1, M2, or M3 chips are certainly better but the iMac Pro performs well, with only slight variations washing up during video export time, for instance. However, it should be noted that it is inevitable that there will come a time when it would not be keeping up ever again.
