Sony today announced an addition to its PlayStation family of entertainment systems, with the new PlayStation 4 Pro (PS4 Pro). The PS4 Pro isn't meant to succeed the PS4, and is still a "current generation" console, in that all of its games are compatible with the PS4, and there won't be PS4 Pro-exclusive games. What sets it apart is higher-resolution game rendering that looks best on 4K Ultra HD TVs. This doesn't necessarily mean that the games are being rendered at 3840 x 2160 pixels. They could be rendered at resolutions higher than 1080p, and using just the right upscaling algorithms, made to look significantly better than 1080p. Another key visual component is hardware HDR. The PS4 Pro falls in line with Sony's big push for 4K HDR TVs this holiday shopping season.

Under the hood, the PlayStation 4 Pro features an all new semi-custom SoC designed by Sony and AMD. The CPU component sticks to the "Jaguar/Puma" architecture, with 8 cores, but features higher CPU clock speeds. The 8 GB GDDR5 memory is said to run at higher clocks, too, and is bolstered by new lossless memory compression tech by AMD. The GPU component is where the action is. The GPU features over double the shading power of the PS4, and is based on the "Polaris" GPU architecture. The PS4 Pro also ships with a bigger 1 TB hard drive. There is seamless interplayability between PS4 and PS4 Pro. PS4 games you already own are being added with higher-resolution content meant for PS4 Pro. The console also has the muscle for PS-VR. For those still holding on to 1080p HDTVs, the PS4 Pro rewards with higher visual detail, more geometric complexity, and better effects, at that resolution. The PS4 Pro starts at $399.
