The Radeon HD 8670A was a mobile graphics chip by AMD, launched on February 2nd, 2013. Built on the 28 nm process, and based on the Mars graphics processor, in its Mars M2 XT variant, the chip supports DirectX 12. Even though it supports DirectX 12, the feature level is only 11_1, which can be problematic with newer DirectX 12 titles. The Mars graphics processor is a relatively small chip with a die area of only 77 mm² and 950 million transistors. It features 384 shading units, 24 texture mapping units, and 8 ROPs. AMD has paired 1,024 MB DDR3 memory with the Radeon HD 8670A, which are connected using a 64-bit memory interface. The GPU is operating at a frequency of 600 MHz, memory is running at 1000 MHz.
Being a mxm module card, its power draw is rated at 45 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.
