AMD parts have had AVX since the Bulldozer core release in Q3 2011. |

Here, you're talking about either VDPAU or VAAAPI support. VDPAU is |
| 41 |
only offered by nVidia cards, and even then you need to run the |
| 42 |
proprietary driver. VAAPI is supported by Intel graphics and ATI's |
| 43 |
proprietary driver. There's talk about using VDPAU as a backend to |
| 44 |
VAAPI, but everything I read on the subect says things like |
| 45 |
'potentially' and 'could be'. |
