| 69 | * shad - Sampling Engine Shadow Map |
||
| 70 | * CK - Sampling Engine Chroma Key |
||
| 71 | * RT - Render Target |

| 72 | * AB - Alpha Blend Render Target |
||
| 73 | * VB - Input Vertex Buffer |

| 74 | * SO - Steamed Output Vertex Buffers (transform feedback) |
||
| 75 | * color - Color Processing |

||
| 77 | * See page 88 of the Sandybridge PRM VOL4_Part1 PDF. |
