Ageia Physx or Nvidia Physx?

Which is the most powerful?
Dedicated or a inbuilt one?
When I went through the benchmarks, Nvidia physx is far pwerful but in some article I read that Nvidia is cheating on physx benchmarks.

So who is king of physx??

 

I thought Nvidia bought Ageia and that they would be integrating it instead of selling stand alone PhysX processor?

 

I am not sure if the 'Physx' thing actually exists. I find it a way for NVIDIA to make gamers spend more money on useless stuff. I have an Ageia Physx card, that does great at consuming power rather than being a 'Physx card'. And as FoxTrot1337 mentioned, NVIDIA bought Ageia.

 

"PhysX" does exist...however the only thing it seems to help is performance in PhysX compatible games and unlocking it. I think nearly all high-end CPU or GPU can do the physics calculation PhysX can do, just cant unlock it in the PhysX game.

 

PhysX does nothing tangible in any game to give you better framerates.

 

Ya I know that but before nvidia bought ageia, there were standalone ageia card sold everywhere. As well as M 1730 has it. So, about Physx i also have same view that its hard to tell in games but can figure out some minor differences during blast or anything destructive situations while gaming.

 

Then whats so special abt Mirrors edge??

 

The problem is, there are almost no games that support PhysX, so I find it impossible to tell that it exists. I heard UT3 and GRAW2 support it. Tried them, with and without it, no difference, like its not there.

 

so physx=UFO
dont if it even exists?
And we are paying for such thing that doesnot exist

 

Pretty much. I have it, I tried it, and I am telling you.

 

And this is a picture of it. Yes, I took it out.

 

its from M1730? So u dont use it anymore??

 

Yes, it's from the m1730. I took it out after I noticed how useless it was. I just have it thrown in a box where I put all kind of electronic stuff together it's doing a better job there, then it was in the system

 

haha that was funny....u just made me laugh...
i guess putting ageia will do something rather than putting nothing..
what u say?/

 

Yes, of course! It will consume some power, produce heat and share the fan with the CPU which will make it (the fan) turn on more often since CPU and Ageia are cooled by the same fan, but for sure, it will have no effect in games.

 

haha I agree wid u...btw what u gonna do with physx in 9800m then?

 

My PhysX card does good at making heat, me and the family gather around the vents and get warmth thanks to Nvidia.

 

Well, high end cards (including the 8800M) are said to support whatever the PhysX adapter does. I would get the 9800's when they're out if they're worth it. BTW the PhysX card is a separate card from the graphic cards.

 

There's only really two games out that make use of PhysX. In order to see the differences you'll have to know what your looking for, firstly, PhysX is hardware physics rendering for supported games that use ALOT of physics objects, or simulations. Mirror's edge is absolutely spectacular at some points with PhysX on. For UT3, you'll have to download the PhysX map pack to really make any use of PhysX since no other maps actually have many, if any at all physics objects.

Here's some downloads from nVidia that all highlight PhysX http://www.nvidia.com/content/graphicsplus/us/download.asp

The old ageia physX card actually works ALOT better than GPU physX when you play PhysX supported games that actually have alot of physics objects, such as Mirror's edge. But the problem is that PhysX is a closed standard because AMD, nor intel support it, and it REQUIRES either an ageia PPU card, or a newer nVidia GPU.

Also, with the release of DirectX 11 and compute shaders, all graphics cards that support DX11 can be used for general purpose computing, including physics simulations, so PhysX will be pointless and dead, which is why intel and AMD refuse to support it.

 

the only game i played that require physx is medal of honor airborne (physx 7.9 i think)

 

Is there any news abt Direct X 11 lately?
hualsay, u got a good sense of humor and ur really helpful
thanks man...btw...I think I should also start using it for heat...
as I feel more cold then probably I will use a rivatuner to overclock it as a switch to increase the heat..."Nvidia-From Graphics to Household-Everyone must buy" "Dont forget to check nvidia toaster.you really get the good brown graphics in the bread with lot of physx,chem and bio"

 

on a side note, using a laptop as heater is not very effective, the most high powered ones use a 120w adapter, while most electic heaters are rated at 1k-2kw.

 

For the GPU... PhysX is designed to offload processing of Physics from the main CPU and divert it to the GPU, where there is extra power available for the GPU to offer the shaders. Average physX processing consumes anywhere from 32-128MB of vRAM, and 8-32 shaders, depending on the amount of shaders available and the workload of the current shaders. For a comparison in regards to the CPU, each shader is running appx 1250MHz. 32 shaders pumping 1.25GHz of dedicated physics calculations are far more powerful than 2 or 4 cores sharing computation on a 3GHz core.

So when done properly, PhysX is a great thing. Mirrors Edge is the first standalone game to incorporate the new PhysX engine OTB. The difference can be seen by one who has seen the game without it. Realistic interaction with objects, thousands of glass shards flying, etc. PhysX is well worth it, so long as you've got plenty of shaders to dedicate a few over.

Depending on the complexity of the physics, it can actually increase framerate due do the workload offloaded from the CPU. It is still very much in its infancy, but now that every nVidia 8x+ user, and many techy ATI users have the ability to run dedicated Physics, I believe we'll see more physics to come.

If you have 112 shaders or more, PhysX is a very good thing. Otherwise, the Ageia PhysX card is a tiny bit better. There just hasn't been a whole lot of apps to use it yet.

 

Hope to use it in future but before Dec21.12.
I cant see my laptop dead.

 

I got my hands on Mirrors edge today and see if there are any changes!!

 

PhysX will die out eventually, and will die off quicker if nVidia continues to lose market share to ATi.

 

My only qualms with PhysX are this: Physics processing is already very impressive. With the bandwidth and power the latest quads and i7 has, and the physics we've seen from games such as the HL2 engine and Crysis, its evident decent physics can be simulated from the CPU alone, while performing other operations. I'd rather see those shaders and vmem used for increasing visual appeal, taking us closer to reality visuals.

And the one thing I've been looking for in game for years that we aren't even close to... character interaction with water. Gimme that and I'll be a happy camper; for now.

 

They are both the same. nVidia bought the technology and implemented it through their own software.

For a desktop, a lot of people add a lower end 8xxx or 9xxx series card and use it as a dedicated PhysX card. It works just like the old Ageia cards, except most 8xxx or 9xxx cards are much more powerful than the original Ageia cards.

 

Did they every make external PPU cards for laptops? Like something that would plug in via expresscard or something?

 

Never heard of external PPU. If there was still ageia company then could have made it but nvidia ....
