Understanding that the research community may well take advantage of the floating-point power on offer and writing code is now made easier as access it 'closer to the metal', how does it help you, the average consumer?

As it happens, many media-rich applications' code is wonderfully parallelisable, meaning that, if coded for, additional plug-ins could take the load off the CPU, place it on the broad, broad shoulders of the GPU, and execute in a more-timely fashion. As an example, during the CTO conference in Amsterdam, Holland, a high-definition clip was transcoded to MPEG2 HD. Running on a Radeon HD 3870 X2, with the Adobe Premier plug-in activated, the GPU ran at 4x a quad-core CPU's speed.

Now, it's clear that extensive developer-relations' support needs to be fostered and promoted before large software houses bother to take advantage of the GPU's massive horsepower, but we see GPGPU as more than just a fad. Rather, the burgeoning industry needs to be helped along via close collaboration with NVIDIA and AMD.

Transcoding HD material or delving into areas such as voice-recognition is still a time-consuming affair and any attempts to leverage the GPU for such tasks is nothing but sensible practice. It opens up the door for AMD to sell FireStream-branded cards at a wonderful premium, too
Versus:
ATI's Avivo Platform - H.264 Decode and Transcode Acceleration on R5xx (http://www.anandtech.com/showdoc.aspx?i=2536&p=1): September 20th, 2005
GPU Accelerated H.264 Transcode (http://www.anandtech.com/showdoc.aspx?i=2536&p=3)
Isn't it time for GPU assisted transcoding? Where and what are the problems? I don't think that firms like Adobe or Nero aren't interested in such solutions, that improve/accelerate video transcoding in the "HDTV" era.

i dont know about voice recognition being time consuming i set up a voice controlled pc for someone on a 1ghz pc it worked great after training and wasnt hitting the cpu too much video trancoding however looks promising

looks like game physics is a bit dead though

It's hard to get the same quality out of a GPU based solution and hardware cost isn't that big a deal when you see the prices for "professional" solutions.

They are using CUDA for their projects. Ok, H.264 Baseline Encoding is not the preferred profile, but it's a small step in the right direction.

Nvidia Analyst Day: Biting Back at Intel (http://www.bit-tech.net/hardware/2008/04/14/nvidia_analyst_day_-_biting_back_at_intel/4)

One software application that was shown off during the Analyst Day was RapiHD – a video encoder designed to run on the GPU using CUDA. Sam Blackman, CEO of Elemental Technologies, the company behind RapiHD, showed a GeForce 8800M GTS running an h.264 video encode completing around 10 times faster than a quad-core Intel CPU. The software will be available in August or September and will be price competitive with current video encoders – expect it to be around $50 US for the standard version.

I can't get it that after years of physics-nonsense, that dead horse is still being beaten.

Maybe because some of us would like to hold onto the hope that we could at some point in the future put to use our old X1xxx, X2xxx, X3xxx, GF 8xxx, or GF9xxx as dedicated physics processing units once we upgrade to a newer video card. :P

And apparently Nvidia is now teasing us with the possibility of Ageia PhysX acceleration on their GPUs. Which leaves ATI as odd man out. Unless of course, MS impletes Direct Physics in DX11.

On the other hand, Physics on a GPU isn't all about gaming. :P

Something about CUDA and x264:

The real questoin is whether they'll have it done before x264's is done ;)

They = Elemental Technologies.
