Was PL processing for Prime or DeepPrime ?
If so, that’s an unfair comparison - as LR is not doing sophisticated noise reduction … Compare, instead, with PL set for High-Quality NR.

No, just High Quality which I think is PL standard.
Exported 60 RAW images (1292 MB total) in order to see what times I get on an Intel iMac 2019 (8-core)
-
DxO Standard preset: 118 s → 11 MB/s
(CPU at 1200%, GPU 1% max) -
LrC defaults + optical + NR: 23 s → 56 MB/s
(CPU up to 500%, GPU up to 60%) -
DPL No Correction preset: 60 s → 21.5 MB/s
-
LrC defaults: 16 s → 80 MB/s
These figures only mean that Lightroom and PhotoLab work differently with
- different effect on processor load and
- different output qualities
Thanks for this comparison @platypus ,
Looks like DxO needs to use more GPU power especially on Macs with a dedicated GPU. I just find it odd that while photo tech and sizes didn’t change much in years, hardware power has become so powerful and yet it takes 2 minutes to export a simple batch of photos (with or without corrections!).
