Well I started downloading the raw pngs for ED. I'll see what I can come up with for some samples encoded at various levels. I'll also see about creating a VC1 version as well as possible a WebM version.

Test not fair for Nvidia imo,
Sandy Bridge is the latest greatest from Intel while GeForce 9500 is a (much) older Nvidia product.
I'd vouch at least for Sandy vs GeForce 460+ to call it a fair comparison, not to mention taking a "more real-world" x264 video as other folks implied.

Flash?
If I remember correctly, Flash video is still not accelerated with Intel graphics. How good is Flash video playback on a low end Sandy Bridge?

Try a trailer for a high profile film like Avatar:Originally Posted by Michael

It is considered fair use.

You tube stuff isn't even moderately close to being demanding. Their HD is really crappy and poorly encoded. It's optimized for web streaming. Also movie trailers are NOT fairuse.

Did you watch the trailer? The HD quality is not bad and the bit rate is something like 6Mbps. What do you consider to be a good bitrate?

Yes, I even have the 1080p file.
It's not very demanding at all, Blu-ray spec has a max of 48mbps combined audio and video, of which 40 can be video, and 20 audio at any one time. This is also a CABAC encoding where a more demanding encode uses CAVLC.General

**** Correction, CABAC is the more demanding on decoding.

I've not downloaded the 1080p version but it is CC.
