Radeon PhysX GPU Acceleration?

We don’t have much information on this aside from the screenshot below but, from the looks of this 3DMark Vantage screenshot, the Radeon HD 3850 is capable of PhysX GPU acceleration. Again, we don’t have any info on this other than what you see here but we thought we’d share anyway. Thanks to EBadit for the screenshot.
 
AMD/ATI playing both sides of the field? :eek:

Are they working with both Nvidia and Intel? Support for both physics engines would be a smart move at this point.

Let's hope that is the case. But it probably won't be. :p
 
I say fake. AMD has not licensed PhysX from NVIDIA, so they can't have PhysX support yet.
 
So if this is true, all those people yesterday claiming Nvidia is cheating, since they now include this support in their drivers, and 3DMark Vantage as well will eat their words then?

They could have licensed Havok though and implemented something in hardware for it.
 
My bullshit sensors are off the scale.

Whoever photoshopped this left the nvidia logo in the top left of the PhysX control panel.

Fail.
 
Its either one of 3 Things;

1) Fake

2) A Hack to fool the PhysX API to run on a Radeon GPU. (Possible, and why it is "messy")

3) A hidden feature set that was developed by ATI, but Locked/Hidden due to Liscense Issues.
 
There are numerous reasons Ati might have already done the work on this prior to aquiring the license. Perhaps this is based on a leaked driver. If it is real, and Ati does hop onto the currently half empty PhysX cart, it would mean that we will get more games that support it. Instead of the token number of Nv sponsored games we would get otherwise.

I'm am skeptical however. I don't see Ati signing onto a totaly Nv controled PhysX, even if it is currently free to do so.
 
probably just AMD fanboys trying to convince more people to buy AMD 4800's......on false pretenses (OMG the 4800 will support Physx too!!!) :rollseyes:

Token number ?! Most of the games we see nowadays are part of the TWIMTBP program and you can be sure that that's the way NVIDIA is going to use to tout PhysX support.

Also, you don't see AMD signing onto a totally NVIDIA controlled PhysX. But does it make sense for them to use Havok, which is part of Intel ?
 
Oh I forgot to post the link that mentions that 14 to 16 games, with PhyX support, will be available by the end of the year and more to come next year:

We also spoke with Brian Burke (Senior PR Manager) and Roy Taylor (Vice President of Developer Relations) on the phone and they had a ton of things to say about PhysX and were obviously all for it. They were happy to announce that 14 to 16 new PhysX game titles would be available before Christmas and double that next summer.

As I know, nVidia really offered them Physx but AMD simply didn't want.
About this screen, fake IMO.
 
Yeah but isnt Physx based on DirectX shader ops anyway? So really this could be plausible. Its not like there would have to be some sort of hardware or emulation going on...
 
It's not plausible at all, what we have here is a screenshot of the Nvidia PhysX panel with the word "Radeon" pasted on it.

Nvidia PhysX is programmed in CUDA, for Nvidia cards, which have completely different shaders to ATI ones.
 
That driver version in GPU-Z is Catalyst 8.6.

Therefore, shens.

And what would that have to do with PhysX? :p
Click to expand...

Nothing. It means that if they went that route they could have physics acceleration of their own. That has nothing to do with the PhysX API which is different from Havok's API. I'm making a point that ATI's cards may not be doing PhysX at all but rather some other form of physics processing onboard (like Havok) that 3D Mark Vantage supports.

Though in the past Havok has been a purely software API and has never been hardware accelerated before to my knowledge.

I'm just speculating here which is all we are really doing isn't it?

No, there are various implementations for game consoles, there's an implementation for multithreaded x86, there's an implementation for the PhysX PPU, and now there's an implementation for Cuda (nVidia's G80+ GPGPU framework).

Cuda is not based on DirectX, and ATi's hardware isn't compatible with Cuda.

But PhysX is the only library that 3DMark Vantage supports. It also uses PhysX for the CPU and PPU routines.

I see. I wasn't sure if 3D Mark Vantage supported anything else. Hasn't it supported Havok in the past?

Well yeah since Havok and physx are 100% compatible right? And vantage also supports havok, right?

They are not compatible APIs. They are very different. I thought 3D Mark supported Havok in the past and I believe it did in earlier versions. I had figured 3D Mark Vantage would have supported it but I suppose it doesn't if Scali2 is correct.

I was just curious if what we were seeing out of the ATI Radeon 4870 wasn't some kind of Havok physics processing being accelerated by the card rather than actual PhysX. PhysX is something that NVIDIA now owns and therefore all their GPUs can support it. However it is possible that ATI built their card to be compatible with the PhysX API in the hopes of one day securing a license for the PhysX API itself.

I too think it may have been photo shopped or something, look at the NV logo. Why would they sell the license to their competition? Unless they really lost it this time...

Yes, I believe they started using Havok in 3DMark2001, and only changed to PhysX recently.
I think the main reason for going PhysX was the PPU support.
There's probably something on it in the readme file or one of the whitepapers on Vantage.

Actually NVIDIA did try to offer PhysX support to AMD, but this far, it seems they didn't accept it, for whatever reason.

However, AMD teamed up with Intel's Havok and I don't see the logic in that, especially since Intel is set to "invade" the discrete graphics card market in the near future and surely won't make AMD's life easier in regards to Havok support, since...you know... Intel is a AMD's biggest competitor...

But what do I know...

I've never even run 3D Mark Vantage. I haven't looked at it at all.

First of all its not a Radeon 4870, its a 3800. Second, at no point in time has AMD hinted about physx support, both AMD and nvidia had been working on a hardware implementation of the Havok engine but as for today its not been implemented. Third, vantage only implemented the physx engine (and therefore can only be accelerated by a physx compatible card) not Havok. Though Havok was supported in 06 and 03 iirc.

Well I got the card model wrong, but the rest of that I know. I wasn't sure what was going on at all. I said that much.

Yeah, what Silus said.

ATI was working on hardware accelerated physics in 2006. Intel bought Havok in 2007. Do you really think Intel is going to let AMD/ATI usurp their cards? AMD has been all over Intel in the news and court systems for unfair business practices... and now they are working together? I don't think so.

We'll you should rethink, cause, AMD announced this a few days ago

AMD and Havok to Optimize Physics for Gaming
 
Somethings fishy...
