Nvidia PhysX vs PPU comparison

[HangTime]

edit: Wrong forum - mods please move to Graphics Cards. Thanks.


Came across this and figured it would be of interest to people who own a PPU (AGEIA PhysX): http://www.firingsquad.com/hardware/physx_performance_update/

Basically it seems as though you actually get better performance running both Graphics AND PhysX on an Nvidia card, rather than using a standalone PPU with the gpu left just for graphics. Or in other words, there is no real value in still having a PPU in your rig providing you have a gf8/9.

Only potential issue I can see is that the benchmarks aren't using very high rez/aa/af. Maybe it would start to slow things down when the gfx cards are under heavy strain...

Very good read, thanks for that.

While i do agree that the test wasn't completely thorough, it does add to my claim that physx cards were always a waste of money (imo).

Ya read that and someone posted something SIM in GPU section for MAV to read.

 

[Pottsey]

That contradicts the other reviews which show the PPU faster then 1 GPU but slower then 2 GPU's. I wonder which reviews are right? Not that it really matters as the PPU is all but dead.

Both UT and Nurien with the 9800, 8800, 4870 all get the same FPS score with the PPU, that to me hints something is wrong with the test setup. No way should two different tests and 3 GPU's all get the same score.

Does 3DMark use NVidia GPU PhysX?

 

[helmutcheese]

Vantage does, but for now Scores are banned from the Database till Nvidia and Futuremark decide of details.

Nvidia do have a patch for PhysX and Vantage AFAIK.

I've just ordered a 4870, so I guess my PPU should stay in my rig till Ati pull their finger out.

I wonder if team red will use this tech?

They eventually will, they just need to add support for it. Nvidia isn't charging them anything to adapt to it.

I believe ati are going down the Havok Fx route.

Intel have said that killing off HavokFX and concetrating Havok on CPU, although they are supposed to be working with AMD on getting Havok to work on the AMD GPU's.

Not being funny, but surely intel wouldn't help their main rival with something?

Intel and AMD working TOGETHER?!?

The enemy of your enemy is your friend.

Looking like they are working on something .

 

[Monkeynut]

I'm still waiting on the Nvidia can o' whoop ass tbh.

 

[Psyk]

Presumably at some point in the future Havok will work on Intel's Larrabee GPUs. Hopefully there will eventually be an open standard so both physics engines will work on any GPU, otherwise we might get to the point that you effectively have two different gaming platforms (i.e. PhysX games will run poorly on an AMD GPU and Havok games will run poorly on an Nvidia GPU unless you have a very powerful CPU).

 

[Monkeynut]

Then Microsoft goes "Yoink!" and nicks all the best bits and incorporates it into DirectX23?

Vantage has a huge boost from the physx acceleration
