Radeon HD 6970M. AMD's fastest mobile chip to date has been doing the review rounds recently and the response has been unsurprisingly positive. Most modern games failed to trip up the 6970M even at 1920 x 1080 resolution, though the usual suspects of Crysis and Metro 2033 did give it a little bit of grief. All in all, the leap from the HD 5870M was significant, although NVIDIA's still relatively new GeForce GTX 485M has managed to hold on to its crown as the most powerful GPU on the mobile front. Benchmarks, architectural details, battery life tests (what battery life?), and value-adding enhancements await at the links below.
