The Radeon HD 7670M was a mobile graphics chip by AMD, launched on February 17th, 2012. Built on the 40 nm process, and based on the Thames graphics processor, in its Thames XT variant, the chip supports DirectX 11.2. The Thames graphics processor is an average sized chip with a die area of 104 mm² and 716 million transistors. It features 480 shading units, 24 texture mapping units, and 16 ROPs. AMD has paired 1,024 MB DDR3 memory with the Radeon HD 7670M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 600 MHz, memory is running at 900 MHz.
Its power draw is rated at 20 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. Radeon HD 7670M is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
