DxO 5 vs DxO 6 vs LR Semi scientific comparison

I have run some files (PDR tests) in lightroom, DxO 5 and 6 converted them into 16 bits TIFF and then performed a noise estimation using Siril original files are ISO 1600

What it is apparent is that DxO 6 improves on the HQ and DP method vs DxO 5 although marginally. The new DeepPrimeXD has 1 stop noise reduction over deep prime on the same software version

Those are mathematical comparisons they cannot evalute image quality or artefacts as the sample images are slighlty defocussed but it gives an idea of the fact the noise reduction is more aggressive and powerful now

It has also to be noted that exporting from DxO 6 with noise reduction OFF is identical to exporting from lightroom with default settings this has also changed from DxO 5

Overall DxO 6 DeepPrime XD has a gain of 1.29 stops over DxO DeepPrime while DeepPrime on its own is 0.28 stops better in my sample case here

The scale is bits value over 16 bits. Do not use this measure as proxy of dynamic range improvement it is not the same thing.

A processing remark on my system XD runs around 5 times slower than HQ and DeepPrime
