I processed an A1 file with DxO PureRAW and Topaz DeNoise AI for comparison. The image has been cropped to 2K resolution and presented here at that resolution, so what you are seeing is 1:1 pixel resolution. The original ARW file was opened in Topaz DeNoise using their RAW workflow, with the settings set to Auto. The DXO files were also opened using their RAW workflow, and since there are not processing settings, processed at DXO's settings. The ARW original and the DNG files produced by DXO and Topaz were unedited except for the crop and I applied +0.5 stop of exposure correction.
I find that both do an excellent job of reducing noise and retaining detail. I find that the DXO processing go well beyond that and applies a lot of sharpening and contrast. Too much for my taste. It is easy to apply sharpening or contrast/clarity/texture and I prefer to do that myself rather than have it applied to the DNG file.
YMMV.
