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 is the first PlayStation console to use the [[wikipedia:x86|x86]] architecture, a semi-custom 8-core AMD Jaguar CPU at 1.6 GHz. One of the cores is utilized separately only for low-power background tasks. The CPU shares its place on an APU chip alongside a semi-custom AMD GCN Radeon GPU supported by 8 GBs of GDDR5 RAM at 2.75 GHz, while 256 MBs of DDR3 RAM is used only for background tasks.
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 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.
