According to DxO staff based on a recent post here (16 Months Later: Still No Universal App for Apple Silicon - #11 by Lucas), DxO PhotoLab 5 is now using Tensor Cores in NVIDIA GeForce RTX GPUs.
It would be great to have some users here that have both DxO PhotoLab 5 and an NVIDIA RTX GPU to post new results in the Google spreadsheet (DxO DEEPPrime Processing Times - Google Sheets).
