NVIDIA Tegra 4 could be based on Kepler
Tegra 4 may be based on the Kepler architecture. According to the vr-zone information, Tegra 4 will not only beat but leapfrog the competition (Mali-T600 Serie and PowerVR SGX54x).
One subject of our discussions was Project Denver and the pace of its development, but also the development of Tegra 4 i.e. T40. As we all know, Tegra 2 and Tegra 3 use what is essentially NV4x-class GPU (GeForce 6000, 7000 Series, RSX from Sony PlayStation 3). As such, we were not surprised to hear that benchmark results are not ideal against the competiton. Truth to be told, if Imagination Technologies and ARM took one more year to beat what is an eight year old PC architecture, it would be borderline ridiculous.
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.
