NVIDIA today started off its GeForce 400M notebook graphics line by launching the series' highest-end model. The GeForce GTX 480M has almost three times as many shader (effects) cores as the 285M it replaces at 352 and carries the hardware tessellation, cache and other changes that make it a generational leap. NVIDIA claims that the 480M can be as much as five times faster than ATI's Mobility Radeon 5000 series in graphics duties and 10 times faster encoding video when using technology like CUDA or OpenCL.
