PlayStation 4 Pro or PS4 Pro for short (originally announced under the codename Neo) was unveiled on September 7, 2016. Its model number is CUH-7000. It is an updated version of the PlayStation 4 with improved hardware, including an upgraded GPU with 4.2 teraflops of processing power, and higher CPU clock. It is designed primarily to enable selected games to be playable at 4K resolution, and improved quality for PlayStation VR. All games are backwards and forward compatible between PS4 and PS4 Pro, but games with optimizations will have improved graphics performance on PS4 Pro. Although capable of streaming 4K video from online sources, PS4 Pro does not support Ultra HD Blu-ray. Additionally the PS4 Pro is the only PS4 model which can remote play at 1080p. The other models are limited to 720p.
