Changes

The '''PlayStation 4 Pro''' (codenamed Neo, 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 PlayStation 4 with improved hardware to enable 4K rendering and improved [[#Hardware_features_and_peripherals|PlayStation VR]] performance, 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, allowing games to 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 4 (Pro) will prove to be a monumental task owing to the complexity of x86_64 and the Radeon-based GPU.

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. Rendering games at 4K resolution is achieved through various rendering techniques and hardware features; PlayStation technical chief Mark Cerny explained that Sony could not "brute force" 4K without compromising form factor and cost, so the console was designed to support "streamlined rendering techniques" using custom hardware, "best-in-breed temporal and spatial anti-aliasing algorithms", and "many new features from the AMD Polaris architecture as well as several even beyond it". The most prominent technique used is checkerboard rendering, wherein the console only renders portions of a scene using a checkerboard pattern, and then uses algorithms to fill in the non-rendered segments. The checkerboarded screen can then be smoothed using an anti-aliasing filter. Hermen Hulst of Guerrilla Games explained that PS4 Pro could render something "perceptively so close [to 4K] that you wouldn't be able to see the difference".[https://en.wikipedia.org/wiki/PlayStation_4#PlayStation_4_Pro]

===Potential roadblocks===Due to the PS4's [[POS_(Pong_Consoles)_CPUs_and_Other_Chips#x86_CPUs|x86 architecture ]] and FreeBSD-based operating system, emulators for the device will, by and large, be very unconventional. Despite the x86's instruction set being huge<ref>{{cite web | url= https://en.wikipedia.org/wiki/x86_instruction_listings | title= x86 instruction listings | Wikipedia}}</ref>, a trait that would typically lead to years of development time by emulators, it opens the ability for pre-existing hypervisors to do the heavy lifting, eliminating the need for a recompiler. There is also, as of this time, little to no documentation on the GPU (a modified Radeon 7970M with disabled stream processors) used in the PS4's APU, and it will require a complete re-implementation by emulator developers. In recent years many [https://www.playstation.com/en-us/games/pc-games/ PlayStation 4 (Pro) exclusive titles are now being ported to PC] with [[#Enhancements|enhancements]], so similar to [[PlayStation_5_emulators#Emulation_issues|PlayStation 5]], [[Xbox One emulators#Emulation issues|Xbox One (X|S)]] and [[Xbox_Series_X_and_Series_S#Emulation issues|Xbox Series X|S]] situations this '''could''' lead to a decreased interest in development. Having said that, there are still considerable amount of games exclusive to those consoles, this includes games for both PlayStation 4 (Pro) and Xbox One (X|S) that haven't been ported and titles lacking enhanced/next-gen update for PC. See [[List of notable ports#External_links]] section for all of those games.
