SourceIn the discussions surrounding the launch of NVIDIA Kepler (GK104 - GTX 680 and GK107 - GT 640M) architecture, we learned a lot of interesting details from NVIDIA engineers and marketing staff. Interested in GPGPU in a smartphone?
According to the sources in the know, Tegra 4 will utilize a GPGPU-compliant, i.e. CUDA-compliant graphics core which is very power savvy. Since a single Kepler-based 20W GPU is enough to run Battlefield 3 with Ultra details in 1366x768 resolution, a 1W GPU should be more than good enough to run Angry Birds in current and next-gen smartphone and tablet designs. Also, with the breakthrough in smartphone i.e. superphone design, you can expect that next generation of superphones such as Motorola's Droid Razr MAXX to carry 2500-3300 mAh batteries, and that will get you both the desired thinness and long battery life.
