The IMX6 contains 2D and 3D GPU support from Vivante with some variations based on the specific IMX SoC:
</p>
<ul><li>IMX6DUAL/QUAD:
<ul><li>Vivante GC2000 (3D GPU)
<ul><li>Clock: 600-800MHz (the IMX6 clocks this at 533MHz)
</li><li>176Mtri/s
</li><li>1000Mpxl/s
</li><li>OpenGL ES 1.1/2.0/3.0
</li><li>OpenCL 1.1 EP
</li><li>Cores: 1
</li><li>Shaders: 4 (Vec-4) and 16 (Vec-1)
</li></ul></li><li>Vivante GC355 (2D GPU - vector graphics)
<ul><li>300Mpxl/s
</li><li>OpenVG 1.1
</li></ul></li><li>Vivante GC320 (2D GPU - blit)
