NVIDIA: features of Tegra 2

NVIDIA sent over a whitepaper last night with some of the capabilities of their new mobile CPUs/GPUs, notably Tegra 2. Tegra 2 and the new Cortex-A9 dual core chips have many new gaming-focused technologies that reduce memory usage, improve battery usage and render shaper graphics.


  • Early-Z support to filter out non-visible pixels
  • Integrated Pixel Shader and Blend Unit
  • Pixel Cache, Texture cache, Vertex, and Attribute Caches to reduce memory transactions
  • Unique 5x Coverage Sampling Anti-aliasing (CSAA) achieves sharper rendering at lower memory bandwidth
  • Advanced Anisotropic Filtering (AF) for high detail textures
  • Custom Memory Controller improves GPU performance and reduces power consumption
  • Improved Power Management

    Among the technologies include improved
    Anisotropic Filtering (AF) which NVIDIA claims
    superior to that of GeForce desktop GPUs.

    The new GPU is 61% faster than Galaxy S phones, the iPad, and iPhone.

    Early-Z is a promising new GPU technology that utilizes a small internal buffer to increase performance. With it, non-visible pixels in a 3D space no longer need to be rendered by the GPU until they’re visible saving CPU & GPU cycles for other things. Until we know how easy to implement, we can’t be sure if developers will actually use it, though.

    Flash is hardware accelerated by Tegra 2. With performance like this, Flash could
    become a viable development platform for Android.

    We can’t wait for Tegra 2 and seeing what all that improved power management means for Android’s abysmal battery consumption. We just hope Spectral Souls supports it when the hardware starts coming out.
