AMD Radeon Pro 455 is a mobile GPU based on AMD’s Polaris architecture built upon 14nm FinFET manufacturing process. The chip can be found in the high-end configurations of 2016’s Apple MacBook Pro Retina 15 Late and uses 768 shaders clocked at 855 MHz base clock speed. The memory configuration uses the 128-bit bus, 2GB of GDDR5 VRAM clocked at 5000 MHz.
As like the rest of the Polaris-based chips from AMD, the Radeon Pro 455 supports the same features like DisplayPort 1.3 and 1.4, HDMI 2.0, AMD FreeSync and DirectX 12 renderer, although the latter is only supported on Windows 10. The GPU is rated at slightly below 35W TDP.
