AMD Radeon HD 6650M Photo AMD Whistler Photo
The Radeon HD 6650M was a graphics card by AMD, launched in January 2011. Built on the 40 nm process, and based on the Whistler graphics processor, in its Whistler LE variant, the card supports DirectX 11.2. The Whistler 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 8 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 800 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. Radeon HD 6650M is connected to the rest of the system using a PCI-Express 2.0 x16 interface.
