Following the announcement of the new Apple MacBook Pro, AMD has launched the Radeon Pro 400 series of power-efficient graphics cards for laptops.

The range spans the Radeon Pro 450, the Radeon Pro 455, and the Radeon Pro 460, all of which are available in various models of the new 15-inch MacBook Pro. All are based on AMD’s latest 14nm FinFET Polaris architecture, as used in desktop gaming cards like the RX 480, and all have a thermal envelope of less than 35W.

AMD claims that the Radeon Pro 400 series features “the thinnest graphics processor possible,” thanks to the use of a die thinning process that reduces each wafer of silicon used in the GPU from 780 microns (0.78 millimetres) to 380 microns.
