When Sony first announced the PlayStation 4, they revealed that the next-gen console will support 4K videos, but not 4K gaming. Now Sony’s Mark Cerny, the lead architect on the PlayStation 4 hardware, explains why 4K gaming isn’t feasible just yet.
Speaking to the Japanese press about the PlayStation 4 hardware, Cerny said that he’s “personally very interested in 4K”, but that the technology is still new and requires lots of horsepwer to run. Cerny explained in simple terms why there isn’t 4K gaming on the PlayStation 4:
“If we consider purely memory bandwidth, with 4K, securing 2 displays worth of display buffer requires 10GB/sec. That just for simply displaying. This is our simple answer for why we’re focusing on just the Full HD experience.”
By “full HD”, Cerny is talking about 1080p which PlayStation 4 games will support (what we’ve seen so far). There are only a handful of 4K television sets available, and they retail for many thousands of dollars. 4K gaming and 4K movies are still many years away, as other technology components need to catch up to the massive resolution of these displays.
Sony said last month that the PlayStation 4 will support 4K movie playback and downloads, but added that a 4K movie can easily top 100 GB in size.
