[quote]OsirisBlack, a well-known insider on Neogaf, has leaked a ton of interesting new details about PlayStation 4 Neo (also known as PS4K). According to the OsirisBlack, this PlayStation Neo information comes straight from the reliable developer source. So without further ado, here are all the information OsirisBlack shared by Sony’s next big thing in the gaming market.
PlayStation Neo (PS4K) GPU is going to be twice (2X) as powerful as the Standard PlayStation 4 and much faster. The source did not reveal exactly how fast the GPU is going to be, but it was confirmed that it will be running at a higher clock speed while being much smaller than the original.
About the price, the source revealed that PlayStation Neo is currently priced at $399, however, this might go up by a $100 more (to $499) because Sony is considering adding a better CPU which would raise the price. However, the source added that they have been guaranteed that the price of PS4 Neo will be no higher than $499. Furthermore, there will not be any trade-in program for current PlayStation 4 owners at the time of PlayStation Neo launch, but this could change in future.
Coming to the specs, in a thread on Neogaf, OsirisBlack revealed PlayStation Neo will offer 5.5 teraflops performance ($599 price point in this thread has being clarified by Osiris, and we have mentioned the details about it above) and will have a 4K Blu-Ray player and will upscale games that are not natively 4K.
Additionally, OsirisBlack revealed that few lucky developers have already received PlayStation 4K Dev Kits and they are making games that will directly target and take advantage of the higher specifications of the PS4K.
On the topic of performance upgrades for current games when played on PS4K, the source made it clear that there will not be any performance upgrades for current PS4 games by being played on PS4K. Any performance benefits to current (and old PS4 games) for PS4K will arrive via Patch Per Game and Per Developer. When asked if this was going to happen the response was
“Its a possibility but doubtful with the exception of a handful of games.”
OsirisBlack went on to list TWO GAMES that are already in development for PlayStation 4K: “Capcom’s Deep Down (a big surprise for those who thinks this game is already dead) and GOW4 (this is the exact term written on the sheet, and the only assumption that comes to mind if God of War 4)”
There were more games on the list but these are the ones that stood out the most, according to OsirisBlack.
UPDATE:
There were few mistakes in the article due multiple post from Osiris on Neogaf). Here is all the clarifications:
Sony is currently testing two different PS4 Neo models, out of these two only ONE will be selected for consumers. The first PlayStation 4 Neo variant offers a 4.2TF performance and has a Jaguar CPU and internally carries a price tag of $399.
The second variant of PlayStation 4 Neo offers a 5.5TF GPU and comes with a brand new CPU and carries a price tag of $499. Sony planning to release PlayStation 4 Neo either at the end of 2016 or before March 2016. If Sony decides to go with the $499 variant of PlayStation 4 Neo then it will be the first time in over a 10 Years time Sony will went with an External Power Supply.[/quote]
