[Fud] ATI Probing PhysX on GPU

post #1 of 20
Thread Starter 
If anyone remember seeing these particular "leaked" specs for RV770:

you will recall seeing a mysterious "Game physics processing capability" mentioned. Well, according to Fudzilla this means that the card will support PhysX.

Computex 08: It will happen


We've learned that ATI will go for Physics, but it’s not that surprising after all. You might remember the ATI brick demo that they did a few tradeshows back, which was supposed to discourage the Ageia guys and their hardware chips.

At the time, ATI claimed that its new Shader model 4 card with R600, as the first one, can do better physics than PhysX chip.

Well, if Nvidia can run Physics on CUDA, so can ATI with the GPU, but both companies still need to do some work on this rather complicated piece of software.

Nvidia will definitely be the first one with this PhysX on GPU driver and ATI will follow at some point. The big advantage that ATI has is that the company can also support Intel’s Havoc and play on both courts.

I know I find this rather hard to believe, but it's interesting nonetheless. And remember, it is Fudzilla so do take this with a healthy amount of NaCl.

I'm suspecting they put some amount of latent support for this in the 2xxx series and up, so that when the technology is ready it will just be available through a driver update.

Because Intel doesn't find AMD as a threat to them, unlike Nvidia.

Compared to Nvidia, ATi has a pretty good relationship with Intel (who now owns Havok). It's not unreasonable for Intel to let ATi cards support Havok if it would hurt Nvidia which is Intel's biggest threat at the moment.

So Intel just ignores that AMD owns ATI now?

AMD doesn't have a proc that can keep step with Core 2, let alone Nehalem. Intel isn't worried about AMD at all for that reason...that and they can always cheat to win.

It's because AMD is a third party in this. Since nvidia owns phsyx, it wouldn't make sense for them to use the competing technology, Havok.

AMD gets the opportunity to support both technologies and let the best one win, while nvidia and Intel duke it out to see which one takes dominance.

They don't ignore it, but it doesn't really effect their strategy. Think about it this way: If CUDA takes off, for certain applications where a fast CPU pays off right now, the GPU begins to be more important. Intel profits a lot more from faster CPUs than they do slower ones. CUDA could potentially mean more people buying less powerful CPUs and more of the less expensive ones. For Intel, this is going to mean a loss of money. In order to prevent this from happening, Intel needs to cut back Nvidia's marketshare. Because they don't currently have a competing product themselves, that job is left to ATI. So, it makes sense for them to be willing to help ATI make their product more compelling. It's basically the same story with SLI+Nehalem, it's not really a mistake. Intel just doesn't want SLI support.

Yes, AMD does have the potential to make money because of this, and they are Intel's competitor. However, consider the circumstances. The most competitive market between AMD and Intel right now is servers. Intel's biggest problem here is scalability, and their answer to this problem is Nehalem. Nehalem isn't meant to be a revolutionary desktop processor, and in fact for single threaded applications I think you will have to look hard to find a big improvement. What it really is, is Intel's answer to Opteron scalability and the real improvement with Nehalem is with multithreaded applications and scaling. So, even if ATI gains marketshare in consumer graphics, Intel is planning to cut in on AMD's server marketshare so it will balance out in the end.

Edit: Wow, post number 200.
