How many 2/4-socket server boards still have Ati Rages? Or other low-end gpu, for the matter.
Good point!! all future CPU are going to be multi-core, and more cores every year. Even 4W atoms are multicore. I am pretty impressed with ffmep-mt performance:The main risk to shader-based decoding IMO is multi-thread decoders maturing and fast CPUs becoming sufficiently cheap and power-efficient that the community loses interest in GPU decode before it gets fully implemented.
- Atom 8W cpu can decode 720p video.
- Core 2 duo 2,2Mhz, 2 cores, 40W, can decode 1080p 40Mbps video.
What could achieve an 8 - 12 cores opteron?![]()
Overkill is a time-honored tradition, particularly when hunting birds :

Punt guns were eventually outlawed in most areas, since there was a real risk of "running out of birds" if their use was continued. I think the record was ~130 birds taken with a single shot.

On this page, video decode using 3d engine is todo for r600.

And on this page, g3dvl (video decode?) for r600 is WIP.
Hu?
I wouldn't want to be doing any kind of heavy processing on a laptop. For those devices it is dedicated decoder or nothing. Reason being that most laptops are built to push the thermal limits of their components. Add heavy processing onto it and you're going to be hitting the overheat kill switch. Even with shader-assisted decoding, you're still going to be running the CPU too hard too consistently to keep properly cool. I would say that about 50% of laptops I've come across can hit the overheat kill switch if you run the CPU at or near 100% for half an hour.
And FYI: that broadcom device I mentioned is actually a LAPTOP card, so for that application, $50 and you have a LINUX SUPPORTED HD video decoder. It REALLY REALLY is the stationary HTPC-type devices that are going to benefit most from assisted video decoding. And yes, the broadcom device will work in a desktop system, but add in $100 for the socket adapter from mini-PCI-e to PCI-e X1.

And the decoder -- crystalHD BCM7001x -- they go for $50+.
** so for a desktop, you're looking at $150 (significantly more than the price of a sufficient video card). For a laptop, $50, which is about the lower limit for a video card that *might* be enough (or might not be).
