So what do we know about the rumoured PlayStation 4.5? In the wake of last week's post-GDC outing of the hardware by Kotaku, we have independently established that it's real and that Sony's R&D labs have prototype devices, and we also have more than one source referring to it as PlayStation 4K, the name we'll be using for now. And this is where things become slightly strange - because while more GPU power is being offered to developers, realistically it is nowhere near enough to provide native 4K gaming at the same quality level as current 1080p titles. The full extent of the spec is a current focus of enquiry for us, but realistically, it is simply impossible to cram the equivalent of today's top-end PC graphics hardware into a console-sized, mass-market box.
Everything we've heard positions PlayStation 4K as a machine capable of playing current and next-generation ultra HD media, while also offering support for other aspects of the 4K spec, such as high-dynamic range and a wider colour gamut - aspects of the 4K spec that could be introduced to gaming. However, in terms of additional computational power, we've got be realistic about what Sony can deliver with a mid-generation refresh.
We can say that with some degree of certainty because PlayStation 4K will almost certainly use an evolved version of the APU technology used in the current console. Once again we will see semi-custom versions of AMD's CPU and GPU technology integrated into a single, console-friendly processor, and thanks to the firm's openness with its technology roadmaps, we have a good idea of the base building blocks Sony has access to in building its next PlayStation.
We also know about the fabrication technologies available. PlayStation 4 and Xbox One arrived when 28nm microprocessors were firmly established, and right now the industry is moving on to 14nm and 16nm chips using 3D 'FinFET' transistors. Shrinking transistors and innovative new architecture are what make generational leaps in computational power possible.
Wir wussten doch schon vor drei Jahren das es nur in Richtung einer All in One Konsole gehen kann... Umsatz wird fast nur noch mit Streaming gemacht. TV ist integriert, Video sowieso,... MS ist einfach schneller als Sony und durch das OS dichter dran an allen anderen Devices... Handys usw. Verschwimmen wird noch der Unterschied zum PC, da Komponenten nach belieben gewechselt werden können, wenn sie gewisse Specs einhalten... da müssen wir tapfer sein. Das Geheule am anderen Ufer wird uns sirenengleich einzulullen versuchen...
