PlayStation 4.5 4K

Is Sony coming with a new PlayStation console? It sure looks like it after last week's post-GDC outing of the hardware by Kotaku. Sony's R&D labs have prototype devices of what seems to be a mid-generation console, referred to as PlayStation 4.5 or PlayStation 4K, indicating that it should be possible to play games and other media in Ultra HD with the new gaming platform.

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.

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.

Why produce a mid-generation refresh of the PlayStation 4? Perhaps the answer lies in the major generational improvements in silicon chip production technologies over the last decade: the ability to shrink microprocessors and cram more transistors onto them, making them more powerful, is slowing down. By necessity, consoles may need to move onto a refresh cycle - a process of gradual improvement as opposed to generational leaps in performance. Just like PC hardware, in other words.

However, there is quite a lot of skepticism if Sony will truly be able to cram the equivalent of today's top-end PC graphics hardware into a console-sized, mass-market box. And if they manage to do that, what will happen to the PS4 games? Will they be upgraded drastically or will only new games be playble in 4K Ultra HD?

Either way, we are excited about the idea of a Sony PlayStation 4K and hope te learn more about Sony's plans for a new console soon! It would be great to play racing games in Ultra HD on console, seated in our Playseat® racing simulators !
