AMD's new ATI Mobility Radeon HD 4860 and HD 4830 chew pixels with 40nm teeth

ATI Mobility Radeon HD 4850 vs. ATI Mobility Radeon HD 4860

Don't get too comfy, NVIDIA. AMD showed up today with mobile video cards of its own, the new ATI Mobility Radeon HD 4860 and HD 4830. The cards are working off of AMD's new 40nm process, with DirectX 10.1 support, dual DisplayPort out and 1080p acceleration claims galore (or 2560 x 1600, if that's your thing). The 4860 sets itself apart with GDDR5 memory, and both cards do ATI PowerPlay, ATI PowerXpress and ATI Switchable Graphics for power saving and maximum buzzwordage. The cards will be first available in ASUS laptops in Q2 of this year.
