CoreAVC with CUDA

[suryad]

Has anyone tried that out yet? The latest version of CoreAVC apparently uses that to offload all the work to the GPU instead of using the CPU. I am a bit curious. I know it wont work on my 8800 Ultras.

 

[Bludd]

You need a GPU with VP2, which is G92 and newer.

I think it is only worth it if have a slowish CPU and not really a super-powerful GPU due to it going into high-performance 3d mode which spins up the fans and generally makes it much more noisy.

It's still pretty dope, though.

 

[suryad]

Yeah I think its a sweet idea as well. I dont usually have any problem playing 1080p stuff on my machine. I was just curious but I bet if I used that full time, my electricity bill wont like it. Also I wonder how it deals with SLI. I mean does the workload get split between the 2 cards? Or is it just one card gets used? Curious....

 

[Bludd]

I don't think the VP2 supports SLI. AFAIK, the VP2 runs at something like 400 MHz and is basically the same on every board it's on regardless of the GPU.

I should hope not!!

I would expect you to bve able to run at least 2 1080p streams simultaneously on that CPU with zero slowdown.

* You will also need drivers 182.05 or higher from NVIDIA

Nice to see this kind of stuff catching on.

Oh so is that some kind of chip or something thats separate from the regular video rendering bits that get utilized when playing a game or something?

Yeah true Then again I have the speedstep enabled so its not like the cpu is running at that speed all the time anyways. I am not sure how effective that technology is to ramp up the cpu power when needed.

Well, I don't know how separate it is physically. You can glean some info on it from this email correspondence between Donald Graft, a developer of free video utilities, and some nvidia engineers:

How come it doesn't support 9400 which is IIRC renamed 8500 ?

Good question. I just now went to their website.

What devices support Cudo in CoreAVC?

Solution So what NVIDIA CUDA cards are support? Officially they are:
NVIDIA GeForce GTX 260/280, 9800, 9600, 9500, 8800 GT, 8700, 8600, 8500, 8400, Tesla S1070/C1060, Quadro FX 3700, Quadro FX 3600M, Quadro FX 1700/FX 570/ NVS 320M/FX 1600M/FX 570M/FX 370/NVS 290/NVS 140M/NVS 135M/FX 360M/NVS 130M and higher.

If anyone has a question if their NVIDIA video card supports CUDA, look here to see if it is listed:

NOTE: CUDA cards MUST ALSO support VP2 or VP3. Look at this chart for more info:

So I guess the 9400 GT is supported. If it were me, and I had that card and wanted that software, I'd get it confirmed by e-mail before purchasing.

 

[green.pixel]

Thanks. It's strange that the most advanced video processing chip VP3 is found on integrated 8200/8300 for AMD's platform and 9300/9400 GPUs for Intel's, but not on dedicated cards.

 

[Bludd]

Not really, the VP chips are designed for low power consumption and many laptops have low-end CPUs, so they need acceleration more than for instance a high-end gaming computer with dedicated GPUs and an i7.

 

[green.pixel]

Yes, I agree, but since VP3 is only on nVidia MBs for dekstop users, that limits users' options when choosing a MB if they want VP3. They could alos put it on their low-end dedicated cards like 9400/9500GT and give users freedom of choice.

 

[Sc4freak]

Darn, my aging 8800GTS isn't supported.

 

[pcchen]

They probably use the CUDA Video Decoder API. It's a relatively easy to use API which does not require any complexities of DXVA, and allows a program to use CUDA to perform some post processing (such as deinterlace). Unfortunately this API requires CUDA 1.1 or later devices, that's why G80 devices are not supported.

I think DG disputes that it's easy.

It's relatively easy. I've tried it for a while and it's really much simpler than DXVA 1.0. DXVA 2.0 is a bit better but it's unfortunately Vista only.
