ATI Mobility Radeon HD 4860
40nm RV740 core (the desktop version is called HD 4750) that features less shader cores than the Mobility HD 4850 (640 like the desktop HD 4830) and only a 128 bit memory bus. Because of the high core clock and GDDR5 memory, the card should perform pretty well.
A first review of the desktop HD 4750 (which could be a bit higher clocked than the Mobility Radeon HD 4860 according to the tech specs), the 4750 achieved 6000 points in the GPU test of 3DMark Vantage. This would be a better score than the Geforce 280M in our review scored.
AMD also published a benchmark comparison between Mobile HD 4850 and HD 4860 where the 4860 performed a few percent points better in 3DMark06 in 1920x1200.
At the Cebit 2009, Asus showed us a 15" laptop with a Mobility Radeon Hd 4860 in it which should hit the market at the end of Q2 2009 (hopefully). Our press contact stated that he thinks that the HD 4860 should perform a bit worse than the HD 4850. In the presented pre-production sample there was only a "Mobility Radeon 4500 Series" graphics card installed that scored only a bit above 2000 points in 3DMark06.
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).
