With the PlayStation 4.5 (or PlayStation 4K) having been announced for a while now, Richard Leadbetter of Digital Foundry has decided to address a variety of rumors that are floating around the new version of Sony’s game console.
This mainly focuses around how PlayStation will be able to achieve 4K, something that is most likely beyond the PS4’s capabilities.
It’s likely that PlayStation will use the same process that they did for Quantum Break in order to get the games on the PlayStation 4K up to the proper resolution. This process would involve a resampling system, then go to a 1080p or higher resolution before bumping it up to 4K.
In order to support this sort of resolution, the PlayStation 4K would require a wide variety of other components that could handle everything that Sony would need to do. One of these would be a new GPU AMD that goes from an AMD Radeon R9 270X to an AMD Radeon R9 280X, though that would require an increase in memory and bandwidth that Sony would have to fix.
There’s also the possibility of user division between owners of the original PlayStation 4 and the PS4K, which Leadbetter warns about. There’s also the possibility of a performance gap between the two iterations of the PlayStation 4, like there are with the original Nintendo 3DS and the New Nintendo 3DS, which has already had at least one exclusive game on it (the remake of Xenoblade Chronicles).
Considering that the PlayStation 4K is just a newer version of the PlayStation 4, however, we may not have to worry about the console becoming obsolete; it is, after all, just a PlayStation 4 with better graphics.
