Following Kotaku’s report of the PlayStation 4.5 last week, Digital Foundry now says they have “independently established” that the system is indeed real, with more than one of their sources referring to it as PlayStation 4K. Additionally, they say Sony’s research and developments labs have prototype devices right now.
While developers would receive more GPU power with the new PS4 model, they say, “Realistically it is nowhere near enough to provide native 4K gaming at the same quality level as current 1080p titles,” as it isn’t possible to put the equivalent of high-end PC hardware into a console.
Based on everything they’ve heard, Digital Foundry says PS4K would be capable of playing current and next-generation ultra HD media, while also supporting other aspects of 4K, which could be introduced to gaming. “However,” they add, “in terms of additional computational power, we’ve got be realistic about what Sony can deliver with a mid-generation refresh.”
They then say “with some degree of certainty” that PS4K would almost certainly use an evolved version of the APU technology used in the PS4 right now.
You can read their full report at the link below, where they also speculate that the new model could either be a new, more powerful PS4; an evolved PS4 that adds visual improvements to older titles; or an improved PS4 slim.
