In place of Tegra 4 will come new SoC code-named Logan, which is reported at WCCF Tech, will be more productive than GeForce 8800GT video card or video game console PlayStation 3, with heat dissipation at the level of 2 watts.
Logan, or Tegra 5, will be available in two versions: with a TDP of 1W (for smartphones) and 2 W (for larger devices). The new processor, which will get the graphics system architecture Kepler, will be about five times more productive than Tegra 4 and will be able to perform up to 400 billion floating-point operations per second (400 gigaflops). In addition, Tegra 5 will support OpenGL 4.3 and CUDA 5.
It is assumed that the announcement of Tegra 5 will take place in early 2014 . By the way, 64-bit instructions will only appear in the next generation mobile processor NVIDIA - Tegra 6 Parker.
