In a brand new interview Sony’s Mark Cerny, a man currently charged with the design of the PlayStation 4 hardware and functionality, talks about the system, backwards compatibility and running that 4K resolution for the user interface.
We assume this means that the costs saved from not having BC mean devs get the extra, super-fast RAM, and so on.
And whilst the PS4 doesn’t include the Cell chip, Sony learnt from the development of Cell to make the PS4 so powerful.
4K resolution? Games are “focusing on 1080p”, Cerny says, but it’s entirely possible to render the user interface (on top of the game, as you can now with the PS button) in 4K.
That said, it’s likely that most games won’t do this to save resources – running the UI alone at 4K takes 10 GB/s.
Cerny also talks about the custom chipset (and confirms the PS4 will use ARM’s TrustZone) and reiterates that the console will allow users to play games whilst they’re downloading – something that was mentioned at the reveal but nice to hear again.
He also hints that we should be seeing near-100% take-up on Vita Remote Play for PS4 games, saying that there’s “almost no overhead” and “without pain whatsoever, you will be able to Remote Play a PS4 game.” That’s encouraging, as is the brief mention of off-TV play…
Cerny also states that the operating system will run on BSD, a flavour of Unix.
