ATI Radeon HD 3100
The AMD ATI Radeon HD 3100 (without the Mobility brand) is an onboard graphics card by AMD for the Turion X2 (Ultra) CPUs. It is built in the RS780MC chipset and is basically a HD 3200 with a slower clock speed and some reduced features (some sources say reduced video accelleration). The clock rate and feature set can be different depending on the laptop model. E.g. core clocks of 300 and 350 MHz have been reported by GPU-Z (Hd 3200 up to 500 MHz).
The 3D performance is similar to the HD 3200 one and therefore relatively good for an integrated chipset (much faster than the GMA 4500MHD and a bit beyond the GeForce 9400M). For older or less demanding games the performance may be sufficient.
Using Windows XP, the HD 3200 seems to have problems with current and older drivers, as there is no 2D accelleration. This leads to very slow interactions with windows and scrolling (especially with Firefox as reported in various discussion boards). More information on the topic can be found at Planet 3D Now (de) or the AMD forum.
