ATI Mobility Radeon HD 4830
The Mobility Radeon HD 4830 is a slower clocked Mobility HD 4860 and based on the 40nm RV740 core. Therefore, it is similar to the desktop HD 4700 series. Because of the 40nm production process, the current consumption should be similar to the HD 4670 (according to rumors).
Instead of GDDR5 memory of the HD 4860, the 4830 can be only equipped with slow DDR3 or faster GDDR3. The slower memory and the slower core clock lead to a slower performance.
The features of the HD 4860 should be comparable to the HD 4850 (regarding Avivo HD video functions, Powerplay and the integrated sound chip for HDMI output).
