The Mobility Radeon HD 3670 was a mobile graphics chip by ATI, launched on January 7th, 2008. Built on the 55 nm process, and based on the M86 graphics processor, in its M86-ME XT variant, the chip supports DirectX 10.1. Since Mobility Radeon HD 3670 does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. The M86 graphics processor is an average sized chip with a die area of 135 mm² and 378 million transistors. It features 120 shading units, 8 texture mapping units, and 4 ROPs. ATI has paired 256 MB GDDR3 memory with the Mobility Radeon HD 3670, which are connected using a 128-bit memory interface. The GPU is operating at a frequency of 680 MHz, memory is running at 800 MHz.
Being a mxm module card, its power draw is rated at 30 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.
