The Radeon HD 7670M was a graphics card by AMD, launched in February 2012. Built on the 40 nm process, and based on the Thames graphics processor, in its Thames XT variant, the card 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 placed 1,024 MB DDR3 memory on the card, 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. Radeon HD 7670M is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
