The Mobility Radeon HD 4100 IGP was a mobile integrated graphics solution by ATI, launched on November 1st, 2009. Built on the 55 nm process, and based on the RS880 graphics processor, in its RS880M variant, the device supports DirectX 10.1. Since Mobility Radeon HD 4100 IGP does not support DirectX 11 or DirectX 12, it might not be able to run all the latest games. It features 40 shading units, 4 texture mapping units, and 4 ROPs. The GPU is operating at a frequency of 400 MHz. Its power draw is not exactly known. Mobility Radeon HD 4100 IGP is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
