I just like to mention: i does some measurements on different raw types (camera body), see in here: Budget GPU for PL - #28 by andras.csore.
I copy the relevant tables:
Of course, the performance (Megapixel / second) is based on my PC system, but i think the ratio between the raw types is ‘universal’.
Add-on: also masking (‘manual’ AI, ‘Pre-defined’ AI and standard (like CP)) performance ratios in that thread.
