NVIDIA Presents Support for Windows 7 DirectX Compute
 

In an internal presentation perhaps to its primary clients, NVIDIA presented support for Windows 7 DirectX Compute. For a welcome change, the slides show no signs of NVIDIA's own CUDA technology, and in turn promise huge performance gains when a Windows 7 machine is aided with an NVIDIA graphics processor. The gains NVIDIA predicts range anywhere between 2 times to 20 times over plain CPU-driven processing, focusing on media-related applications such as Cyberlink PowerDirector, MotionDSP vReveal, and of course Badaboom.

DirectX Compute API will be natively built into Windows 7. It supports both existing DirectX 10 compliant GPUs, and future DirectX 11 ones. Along with pledging full support for it, NVIDIA also explains how the GPU becomes an increasingly important component of the PC, being "central to the Windows 7 experience". As a bonus tidbit, it adds that on Windows 7 the SLI multi-GPU technology works 10% faster than on Windows XP.

the slides are quite nice but i would like to see it tested by independent testers.

Any details on whether there are any differences between using DX Compute on DX 10 versus DX 11 compliant hardware?

*does the excited by GPGPU dance*

Same here! I can't wait!

finally, they can just code these apps to be GPGPU and we skip the whole cuda/stream dance, and apps just work... hoooraaaaaaay

yayy, Nvidia promises to support something hardwired into DX and windows 7, something ATI has been doing for years, something ATI did before DX was ready for it.......

Finally? OpenCL has been around. It does the same thing.

They're loosing ground, why nv doing this?
Cuda is better for Geforces... but not supported by others.

OpenCL and DX11 Rulz ^^

Are you excited or is that an Nvidia GPU in ur pants?

This is a good step in the right direction for Nvidia. However, I'd like to see them take the extra step to OpenCL.

CUDA -> Proprietary to Nvidia, but multiplatform
DirectX Compute -> Runs on more than Nvidia hardware, but Windows only
OpenCL -> Runs on hardware from all major players, and platform independent.

yeah i'd like to see much more OpenCL apps as well

btw are there at least some OpenCL apps out there that are good and as fast as CUDA equivalents?

Find me an openCL program that gives he hardware acceleration for video encoding/decoding on H264 plz.

both. i'm excited that nvidia, ATI, and windows 7 are in my pants together having a fun time.

That wasn't your argument. It was that DX Compute is the first of its kind. Hence the "finally". Between OpenCL and DXCS, you'll soon find out that OpenCL will win. It's cross-platform.

i never said first of a kind - i said finally, GPGPU for 7 is here. (which it really isnt yet, but meh)

openCL doesnt do anything for me yet, so it doesnt count either.

I want to see cards. DX11 is useless without DX11 compatibile cards.


CUDA/Stream are destined to be short-lived technologies because they are proprietary.

I doubt OpenCL will gain much traction either because it was made by Apple and Apple puts everything on an extremely short leash (ultimately choking it to death).

An expanded version of OpenGL is more likely to succeed but it will be some time before that happens.

lies

cs 4.0 -> dx10 gpu
cs 4.1 -> dx10.1 gpu
cs 5.0 -> dx11 gpu

it cool to dx11 cards come out i want talk about this picture

"better than XP" , should compare it with vista i think , vista dx10 better thanx xp dx9 , they most compare DX11 with DX10

Vista driver model owns XP
why?, vista drivers are made to run in user level not in the horrible kernel level as in XP

indeed

That's so called , erm , nvidias hyping.

Please let this mean developers will start using the compute shaders for physics processing.

thats the plan, i beleive.


I think intel intends to update havok to work via GPGPU/compute shaders, and then let anyone in on that (cough, mostly ATI since they've been working on it for a while)


hopefully, game devs will use that instead of physx - works on more cards that way.

If only we could get an update on popular physx games (UT3/Mirrors Edge) to do physics on the compute shaders, that way nvidia could drop 40 mbs of size from their drivers... and it would let those few married to physx support to at least consider ati :s

... but I'm sure there's some nvidia contract that will prevent that.

its possible for nvidia to tie Physx into DX11's compute shaders - the problem is that then ATI and intel can use it too.

its not a problem for us, but it is a problem for Nvidia
