The Radeon HD 8670M was a graphics card by AMD, launched in March 2013. Built on the 28 nm process, and based on the Sun graphics processor, in its Sun XT variant, the card supports DirectX 12.0. The Sun graphics processor is a relatively small chip with a die area of only 77 mm² and 1,040 million transistors. It features 320 shading units, 20 texture mapping units and 8 ROPs. AMD has placed 1,024 MB DDR3 memory on the card, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 925 MHz, which can be boosted up to 975 MHz, memory is running at 1000 MHz.
Its power draw is not exactly known. This device has no display connectivity, as it is not designed to have monitors connected to it. Radeon HD 8670M is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
