The Radeon Pro 575X is a professional mobile graphics chip by AMD, launched in March 2019. Built on the 14 nm process, and based on the Polaris 20 graphics processor, in its Polaris 20 XL variant, the chip supports DirectX 12. The Polaris 20 graphics processor is an average sized chip with a die area of 232 mm² and 5,700 million transistors. Unlike the fully unlocked Radeon RX 580X, which uses the same GPU but has all 2304 shaders enabled, AMD has disabled some shading units on the Radeon Pro 575X to reach the product's target shader count. It features 2048 shading units, 128 texture mapping units, and 32 ROPs. AMD has paired 4 GB GDDR5 memory with the Radeon Pro 575X, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1096 MHz, memory is running at 1700 MHz (6.8 Gbps effective).
Its power draw is rated at 150 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 575X is connected to the rest of the system using a PCI-Express 3.0 x16 interface.
