The Radeon HD 8670M was a mobile graphics chip 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 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 Sun graphics processor is a relatively small chip with a die area of only 56 mm² and 690 million transistors. It features 320 shading units, 20 texture mapping units, and 8 ROPs. AMD has paired 1,024 MB DDR3 memory with the Radeon HD 8670M, 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. Rather it is intended for use in laptop/notebooks and will use the output of the host mobile device. Radeon HD 8670M is connected to the rest of the system using a PCI-Express 3.0 x8 interface.
