Back in December of 2018, someone claiming to be a third-party European developer making a PS5 launch title made a post on Pastebin claiming to leak details about Sony's new console. Despite the post providing no evidence to back up the claims, the Internet has nevertheless latched onto it as a potentially legitimate PS5 leak. While the Pastebin post is most likely fake, if it is real, it potentially provides our first details about the PS5 specs.
Here are the PS5 specs, according to the Pastebin leaker:
"specs CPU 7nm ryzen 8 core 16 threads,unknown speed. GPU 7nm Navi arhitecture around 14TF,its gonna be powerful and power efficient,Sony working with Amd for Navi,some sort of Ray Tracing but will not focus on that,more focus with VR and 4k,much better bandwith overall
24GB Gddr6 + 4gb ddr4 for os,we have 32 gb dev kits"
We have no way of verifying if the above information is true, and the fact that the poster didn't even bother to use proper punctuation is suspect. However, some of the claims seem likely, such as Sony working with AMD on the PS5, as Sony has collaborated with AMD in the past. The PS5 having ray-tracing graphics has also been rumored in the past, and it seems like a given for next-gen consoles.
The supposed focus on VR and 4K for the PS5 also make a lot of sense. Sony has found success with PlayStation VR on PS4, and it's currently the dominant virtual reality headset on the market, so a PlayStation VR 2 seems inevitable. 4K TVs, meanwhile, have become much more affordable over the last couple of years, and while some expect the PS5 to support up to 8K resolution, it makes sense for it to focus on 4K for now.
While many fans may want to believe this supposed PS5 leak and the information that has come from it, there is more evidence that it's fake than in support of it. Jason Schreier of Kotaku recently said that "the number of people briefed on next-gen is still very limited," and so it's unlikely that a third-party from Europe would have a dev kit as early as December 2018.
Schreier did say that Sony is looking for the PS5 to have more than 10.7 teraflops of power, which would mean the PS5 is more powerful than Google Stadia. Other than that tidbit, though, we know nothing else about the PS5's specs at the time of this writing.
