    The mid-generation console upgrade features the same eight-core AMD Jaguar 64-bit as the original PS4, but with a clockspeed increase from 1.6GHz to 2.1GHz. The graphics engine has also been upgraded to double the performance of its predecessor.
    It now features a custom 4.2-teraflops Radeon GPU with 36 compute units based on a 14nm Polaris core. The original console featured a 1.84-teraflops Radeon GPU with 18 compute units based on a 28nm process. As for memory, the new console uses the same 8GB GDDR5 as the original but with 218GB/s of bandwidth rather than 176GB/s.

    In other terms, the new graphics core should be equivalent to an overclocked Radeon RX 470 yet below the Radeon RX 480. Recent reports claim that the revised GPU runs 36 compute units at a clockspeed of 911MHz, while the Radeon RX 480 runs at 1266MHz. Meanwhile, the original console’s chip performance was roughly just above a Radeon HD 7850 and below the Radeon HD 7870, according to some estimates.

    Even when considering improvements in horsepower on the smaller 14nm process node, however, the new premium PlayStation 4 Pro consumes about 90W more power than the original console with a 310W TDP, versus the original’s 230W to 250W design, depending on the revision.

    Sony’s developer guidelines require 1080p rendering or higher

    Back in June, some developer guidelines were published ahead of the new console’s launch which detailed Sony’s requirements for cross-platform compatibility between the upgraded PlayStation 4 Pro and existing PlayStation 4 hardware.

    One main requirement is that in the future 1080p is the mandatory minimum display resolution for new titles, and when developing at higher resolutions, scaling down to full HD is also an option. Another important requirement is that developers cannot have only PlayStation 4 Pro-compatible multiplayer environments, and that any multiplayer severs must be fully cross-compatible between both hardware designs.

    Beginning with the mid-generation console refresh, developers are also not allowed to create PS4-only or PS4 Pro-only titles, as the company intends to offer equal gameplay functionality to each console design within the same generation. The same requirements will also apply in terms of which controllers and peripherals are supported. More on the company’s new rendering guidelines can be found here.

    PlayStation 4 Pro will not always render at 4K UHD

    Not every new PlayStation title in the future will be capable of rendering at exactly 3840x2160p UHD resolution. In Sony’s recent developer guidelines, there is a “debug mode” offering display buffer resolutions of 3680x2070, 3520x1920, 3360x1890 and 3200x1800.

    The company mentions also in a slide titled “Lower Resolution Strategies” that a game might prepare a 3520x1920 display buffer when a 4K display is connected, prior to upscaling it to UHD resolution in hardware before outputting the image. Most importantly, however, Sony emphasizes it being very important to ensure that the PlayStation 4 Pro framerate “meets or exceeds the framerate” of the same game on the original console.

    HDR content playback coming to all PS4 consoles

    PlayStation boss Andrew House mentioned during the console announcements that the entire PlayStation 4 lineup would be receiving support for High Dynamic Range (HDR) content streaming and playback. This feature will be included out of the box with the PlayStation 4 Pro and PS4 Slim, while the original console will be receiving a software update soon. For the upgraded console this means streaming HDR content at Ultra HD resolution, while for standard consoles it likely means streaming HDR content downscaled to 1080p.
