Well I would say … try to clean those ISO 12,800 and up with Lightroom or C1 Pro and I would like to see the results. The closest you can get to DeepPRIME at the moment is Topaz DeNoise but it’s not as good. If you are using Photolab just for noise reduction I can confirm there is no difference in image quality between DeepPRIME in Photolab 4 and 5 …. On the other hand I can’t comment about Deep PRIME processing time because I rum my old comp on integrated Intel graphic card. Some other users are reporting significant speed bump with Photolab 5. The significant bump in DeepPRIME processing speed is evident with the newer GPU's like the Nvidia RTX series. In addition PL 5's DeepPRIME processing takes advantage of the Mac M1 chip Apple Neural Engine to speed up DeepPRIME processing time very significantly. On Windows, DeepPRIME processing times have improved by as much as 1.5 times depending on the card and hardware. On a Mac, depending on the graphics card and the use of the neural network, PhotoLab 5 will process DeepPRIME as much as 4 times faster than PhotoLab 4 did using the same configuration.
