A custom GPU with 40 customised compute units at 1172MHz will be the real powerhouse of Project Scorpio, enabling native 4K gaming at 60fps. Project Scorpio will also boast 12GB GDDR5, compared to 8GB GDDR5 in the PS4 Pro. 4K UDH Blu-ray is also supported.
Microsoft promised at E3 in 2016 that Project Scorpio will be the most powerful gaming console ever, eclipsing the PS4 Pro and it's own Xbox One S.
There is no design for Scorpio to show off yet or any details on release date or pricing. For more information on Scorpio as it stands, read this article at Eurogamer.
