AMD Baffin Photo
The Radeon Pro 455 is a professional graphics card by AMD, launched in October 2016. Built on the 14 nm process, and based on the Baffin graphics processor, in its Baffin PRO variant, the card supports DirectX 12.0. The Baffin 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 460 1024SP, which uses the same GPU but has all 1024 shaders enabled, AMD has disabled some shading units on the Radeon Pro 455 to reach the product's target shader count. It features 768 shading units, 48 texture mapping units and 16 ROPs. AMD has placed 2,048 MB GDDR5 memory on the card, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 855 MHz, memory is running at 1270 MHz.
Being a mxm module card, the AMD Radeon Pro 455 does not require any additional power connector, its power draw is rated at 35 W maximum. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon Pro 455 is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
