 {{for|other emulators that run on PS4 hardware|Emulators on PS4}}  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 utilized 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 GBs of GDDR5 RAM at 2.75 GHz, while 256 MB MBs of DDR3 RAM is used only for background tasks. Notably The '''PlayStation 4 Pro''' (codenamed Neo, it model number CUH-7000) console produced by Sony Computer Entertainment on November 10, 2016, and retailed for {{Inflation|USD|399.99|2016}}. It is an upgraded version of the first PlayStation console 4 with improved hardware to use the enable 4K rendering and improved [[wikipedia:x86#Hardware_features_and_peripherals|x86PlayStation VR]] architectureperformance, including an upgraded GPU with 4.198 teraflops of processing power and hardware support for checkerboard rendering, and a higher CPU clock. As with PS4 "Slim", this model also features support for USB 3.1, Bluetooth 4.0 and 5.0 GHz Wi-Fi. The PS4 Pro also includes 1 GB of DDR3 memory that is used to swap out non-gaming applications that run in the background, making it easier allowing games to program for than utilize an additional 512 MB of the console's GDDR5 memory. Although capable of streaming 4K video, '''the PS4 Pro does not support Ultra HD Blu-ray'''. Games marketed by Sony as PS4 Pro Enhanced have specific optimizations when played on this model, such as 4K resolution graphics and/or higher performance. For games not specifically optimized, an option known as "Boost Mode" was added on system software 4.5, which can be enabled to force higher CPU and GPU clock rates on existing games to possibly improve performance.[[https://en.wikipedia.org/wiki/PlayStation_4#PlayStation_4_Pro] Emulating the PlayStation 3 emulators|PlayStation 3]] while also having 4(Pro) will prove to be a monumental task owing to the complexity of x86_64 and the same architecture as PCsRadeon-based GPU.

It currently offers the best game compatibility. :; Obliteration:: A compatibility layer for Windows based on Kyty that's in early development. Promising work has been done on this emulator, however it's unable to boot any commercial games. :; shadPS4:: An PS4 compatibility layer. It can only run simple homebrews at the moment. :; psOff:: Yet another compatibility layer. Developer solely focused on the rendering part and recently started to implement the system functions to run some binaries. It renders decently fast, the planned changes will make it almost perfect. It currently doesn't support: multiple command buffer submits, for loops in shader, missing opcodes.[https://github.com/SysRay/psOff_public?tab=readme-ov-file#description] It can currently run Worms W.M.D., Sonic Mania, Tomb Raider I-III Remastered, Undertale, Deltarune and Blackhole with 60 FPS. Red Dead Redemption shows its legal warnings before crashing. :; [[Kyty]]:: A compatibility layer for the PS4 and PS5 made by InoriRus, the creator of Short Waves. It's in the early stages of development. It can boot commercial games such as ''Blackhole'', ''Worms W.M.D'', and some PS5 homebrews with 0.2.0. This is also the first-ever PlayStation 4 emulator with a GUI, and like GPCS4, the emulator is Windows-exclusive. :; [[GPCS4]]:: A compatibility layer for the PlayStation 4. It can show the logos in [https://en.wikipedia.org/wiki/Nier:_Automata ''Nier: Automata''] and ran its first commercial games, ''We Are Doomed'' and [https://en.wikipedia.org/wiki/Sonic_Mania ''Sonic Mania''], in February 2020. It can only run homebrew tests as of June 2022. Furthermore, it appears to be only a side project to test 3D graphics and may or may not become anything serious, but this is unknown as the project's development has halted. As of June 2022, GPCS4 is now a one-person project. :; PS4Delta:: A compatibility layer for the PlayStation 4. It's unable to boot any commercial games and appears to do almost nothing than load some firmware modules. Development has stopped, and the project is archived on GitHub. ;Native:; PlayStation 5:: The PlayStation 5 boasts extensive backwards compatibility with a vast library of PlayStation 4 titles. [[PlayStation_5_emulators#Hardware_features_and_peripherals|This functionality]] allows users to play the overwhelming majority of physical PS4 discs and digital games downloaded through the PlayStation Store directly on their PS5 console. Additionally, some PS4 games may benefit from [[#Enhancements|enhancements]] on the PS5 hardware (similar to PlayStation 4 Pro) if it supports "Game Boost" option, such as experiencing higher or more stable frame rates. ==Enhancements==<div style="overflow-x:auto;width:100%">{|class="wikitable" style="text-align:center;vertical-align:middle;width:100%"|- style="font-weight:bold;"! colspan=2 | Name!
