The '''PlayStation 4''' (PS4) is an eighth-generation console produced by Sony Computer Entertainment on November 15, 2013 and retailed for {{Inflation|USD|399.99|2013}}. It has is the first PlayStation console to use the [[wikipedia:x86|x86]] architecture, a semi-custom 8-core AMD x86-64 Jaguar CPU at 1.6 GHz, whereas one . One of the cores is utilised separately only for low-power, background tasks. The CPU is shared shares its place on an APU chip with alongside a semi-custom AMD GCN Radeon GPU. They are supported by 8 GB of GDDR5 RAM at 2.75 GHz, while 256 MB of DDR3 RAM is used only for background tasks. Notably, it is  Emulation of the first PlayStation console 4 will prove to be a monumental task owing to use the [[wikipedia:x86|x86]] architecture, making it easier to program for than complexity of x86_64 and the Radeon-based GPU. Most projects will inevitably end up going the route of [[PlayStation 3 emulators|PlayStation 3Wine]] while also having the same architecture as PCs.

;PS4Delta===PCSX4 & Fake Emulators===:A compatibility layer Because most people don't understand how emulation really works, scammers try and take advantage of this by making [[Emulator scams|their own fake emulator]] for malicious purposes. The PS4 has seen its fair share of scams, the PlayStation 4most notable and persistent of which being '''PCSX4'''. ItThe scheme is very elaborate and clever, with a website designed to mimic [[RPCS3]]'s currently unable to boot any commercial gameswhile using a similar naming scheme as [[PCSX-Reloaded|PCSX]] and [[PCSX2]] (both of which are legitimate).
