The Radeon HD 6770M was a mobile graphics chip by AMD, launched on January 4th, 2011. Built on the 40 nm process, and based on the Whistler graphics processor, in its Whistler XT variant, the chip supports DirectX 11.2. The Whistler graphics processor is an average sized chip with a die area of 118 mm² and 716 million transistors. It features 480 shading units, 24 texture mapping units, and 8 ROPs. AMD has paired 1,024 MB GDDR5 memory with the Radeon HD 6770M, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 725 MHz, memory is running at 900 MHz (3.6 Gbps effective).
Being a mxm module card, its power draw is rated at 35 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.
