Radeon. The ATI cards are MUCH more powerful. For video, the OSS driver seems to work the best, but if you enable v-sync and set your video output to OpenGL, that works too. You really don't need hardware acceleration.
This can only do 1 HD + 1 SD stream simultaneously. More may work but not in realtime. This is true for other vendors too (AMD, NVIDIA). Though, I believe some NVIDIA chips can do 2 HD streams simultaneously in realtime.
Thanks for the link. Best Integrated GPU for Linux
Now the DRI2 is supported.
Intel chipset could be considered the best solutions for the driver open source present on linux?
Or Ati have better feautures (even on old chipset)?
