== GPU - Graphics Processing Unit
The IMX6 contains 2D and 3D GPU support from Vivante with some variations based on the specific IMX SoC:
 * IMX6DUAL/QUAD:
  - Vivante GC2000 (3D GPU)
   * Clock: 600-800MHz (the IMX6 clocks this at 533MHz)
   * 176Mtri/s
   * 1000Mpxl/s
   * OpenGL ES 1.1/2.0/3.0
   * OpenCL 1.1 EP
   * Cores: 1
   * Shaders: 4 (Vec-4) and 16 (Vec-1)
  - Vivante GC355 (2D GPU - vector graphics)
   * 300Mpxl/s
   * OpenVG 1.1
  - Vivante GC320 (2D GPU - blit)
   * 600Mpxl/s
 * IMX6DUALLITE/SOLO:
  - Vivante GC880 GPU
   * Clock: 600-800MHz (the IMX6 clocks this at 400MHz)
   * 53Mtri/s
   * 266Mpxl/s
   * OpenGL ES 1.1/2.0/3.0
   * Cores: 1
   * Shaders: 1 (Vec-4) and 4 (Vec-1)
   * OpenVG 1.1 (no GC320 on this SoC, so 2D vector graphics is through the GC880)
  - Vivante GC320 (2D GPU - blit)
   * 600Mpxl/s

According to Freescale this GPU supports the following open standards:
 * OpenCL 1.1 Embedded Profile (EP) (Open Computing Language - framework for writing programs that execute across a heterogeneous platform consisting of CPUs, GPUs, DSPs, etc)
 * OpenGL ES 1.1/2.0 (Open Graphics Library - for 2D and 3D vector graphics)
 * OpenVG 1.1 (Vector Graphics Acceleration)

Software Support:
