|
Graphics processor |
VC-1 |
H.264 decode ability |
MPEG-2 decode ability |
Advanced HD Deinterlacing |
Other Notes |
|---|---|---|---|---|---|
| ATI Radeon X1x00 series [includes Radeon HD 2900] | advanced | advanced | advanced | Depends on shader power | Decode done mostly in shader programs |
| ATI/AMD 690G/740G IGP | moderate | moderate | advanced | Video sources only |
GPU is derived from Radeon X700. 740G is a 55nm fabricated version of the 690G. |
| ATI Radeon HD 2400 series / Radeon HD 3450 | full | full | advanced | Video sources only with 2400 Pro, possibly film sources with 2400XT/3450 - not enough data to be certain | UVD adds dedicated silicon for full H.264 and VC-1 decode |
| ATI/AMD 780G IGP [Radeon HD 3200] | full | full | advanced | Disabled with Athlon 64 family, performs like 3470 with Phenom family. | |
| ATI Radeon HD 3470 | full | full | advanced | Seems to be just powerful enough to do it. | |
| ATI Radeon HD 2600 series and HD 3650 and higher | full | full | advanced |
Yes |
|
| ATI Radeon HD 4000 series | full | full | full | Yes |
UVD Gen.2 -- Offers dual stream decode for hardware accelerated PiP 8-channel LPCM support over HDMI |
| NVIDIA GeForce 7-series [includes GeForce 8800GTS/GTX (G80) and GeForce 7050PV IGP] | moderate | moderate | advanced | GeForce 7600GT and higher have the power to do inverse telecine on 1080i | Decode mostly done in shaders programs. |
| NVIDIA GeForce 8400GS (G86) | advanced | full | advanced | Not really, too underpowered | |
| NVIDIA GeForce 8500GT, 8600GT/GTS, 8800GT/GS | advanced | full | advanced | Yes | GeForce 8500 and newer add dedicated silicon for full H.264 and partial VC-1 decode |
| NVIDIA GeForce 9-series and GTX 200 series | advanced | full | advanced | Yes | Offers dual stream decode for hardware accelerated PiP |
| NVIDIA GeForce 8200 IGP | full | full | advanced |
Yes -- with a Phenom |
8-channel LPCM support over HDMI |
| Intel G35 [GMA X3500] | moderate | N/A | advanced |
Video sources only, currently fails inverse 3:2 of 1080i sources |
8-channel LPCM support over HDMI |
|
Intel G45 [GMA X4500 HD] |
full | full | full |
Yes --allegedly, product too new to test |
8-channel LPCM support over HDMI and PAVP support. |

tableau très itéressant.
Et si on utilise son PCHC pour faire du montage video HD (AVCHD), est-ce que les cartes citées conviennent ou faut il un processeur puissnt pour les "recodages" vidéo ?
Merci
