Last I checked it’s true that you can get framerate in the area of or even exceeding that of Windows. What’s rarely mentioned however is that frame pacing can suck (119 frames in 1 second then 1 frame in 1 second averages to 60 frames per second to give an over exaggerated example) and will contribute to stuttery feel despite adequate framerates.

These things run on rather specialised SoCs so it’s not like somebody is going to buy them wholesale to train machine learning models. Valve already monopolised PC gaming market so there’s nowhere to run with that hardware really.

It might be cheaper than either given that Sony subsidises their hardware and PS5 comes with 16GB of GDDR6. Getting PS5 on firmware old enough makes this a very niche thing though.
