The Radeon 3100 Mobile IGP was a mobile integrated graphics solution by ATI, launched on August 15th, 2008. Built on the 65 nm process, and based on the RS780 graphics processor, in its RS780M variant, the device supports DirectX 10.0. Since Radeon 3100 Mobile 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 350 MHz. Its power draw is not exactly known. Radeon 3100 Mobile IGP is connected to the rest of the system using a PCI-Express 1.0 x16 interface.
Based on TPU review data: "Performance Summary" at 1920x1080, 4K for 2080 Ti and faster.
Performance estimated based on architecture, shader count and clocks.
