The Radeon Pro 555 is a professional mobile graphics chip by AMD, launched on June 5th, 2017. Built on the 14 nm process, and based on the Polaris 21 graphics processor, in its Polaris 21 PRO variant, the chip supports DirectX 12. The Polaris 21 graphics processor is an average sized chip with a die area of 123 mm² and 3,000 million transistors. Unlike the fully unlocked Radeon RX 560, which uses the same GPU but has all 1024 shaders enabled, AMD has disabled some shading units on the Radeon Pro 555 to reach the product's target shader count. It features 768 shading units, 48 texture mapping units, and 16 ROPs. AMD has paired 2,048 MB GDDR5 memory with the Radeon Pro 555, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 850 MHz, memory is running at 1275 MHz (5.1 Gbps effective).
Its power draw is rated at 75 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Radeon Pro 555 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
