ATI Mobility Radeon HD 4860
The Mobility HD 4860 is based off of the 40nm RV740 core with less shader cores than the Mobility HD 4850 and only a 128 bit memory bus. Because of the high core clock and GDDR5 memory, the card should still be able to perform comparatively fast.
An initial review of the desktop HD 4750 with similar specifications than the Mobility HD 4860 (but at higher clock rates) shows a score of 6000 points in the GPU test of 3DMark Vantage. According to our benchmarks, this score puts the AMD card above the GeForce 280M.
AMD has also published a benchmark comparison between the HD 4850 and HD 4860 mobile graphics cards and showed that the 4860 was able to perform a few percentage points better in 3DMark06 under 1920x1200 pixel resolution.
At Cebit 2009, Asus showed us a 15" laptop with a Mobility Radeon HD 4860 for a hopeful launch in Q2 2009. Our press contact stated that the mobile HD 4860 may perform a bit worse than the mobile HD 4850. In the presented pre-production sample, there was an unspecified "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 with regards to Avivo HD video functionality, Powerplay and the integrated sound controller for HDMI output.
