NVIDIA is ready to counter the Triple Play

With the release of the G80, NVIDIA will also release a new engine dubbed Quantum physics engine.  Quantum Effects Technology is similar (at least in spirit) to NVIDIA's PureVideo Technology -- a dedicated layer on the GPU for physics calculations.  A few documents alluding to this new engine appeared on public FTP mirrors late last week.

Quantum utilizes some of the shaders from NVIDIA's G80 processor specifically for physics calculations.  Physics calculations on GPUs are nothing new; ATI totes similar technology for its Stream Computing initiative and for the Triple Play physics

NVIDIA and Havok partnered up this year claiming that SLI systems would get massive performance gains by utilizing additional GeForce GPUs as physics processors.  Quantum may be the fruits of that partnership, though NVIDIA documentation clearly states that Quantum will work just fine without SLI.

NVIDIA's documentation claims Quantum will specifically compete with AGEIA's PhysX, yet does not mention who is providing the middleware.  Given that there are only two acts in town right now, it would be safe to say Havok has a hand in the Quantum engine.

Shouldn't the title read "Documents Leak NVIDIA's Quantum Physics Engine", not 'Quatum'?
Anyway, I personally think the name for that is kind of misleading. It implies actual quantum physics calculations, which probably won't be used in games any time soon :). So the havoc physics engine will support this, meaning any game developer using the latest havoc engine will support this type of physics?

Yeah, when I saw that I was thinking, how are they going to use quantum physics in games. It's ridiculous that a word like quantum is just one of those ooooh ahhh words to so many people. I mean naming it quantum physics engine is just straight up misleading; we should sue them when this comes out because it doesn't accurately portray gluons.

ATI will counter by calling their technology the "Relativistic Physics Engine." Perhaps this is all fitting: with the power requirements on future generations of graphics cards, you may need your own nuclear reactor.

I'm going to hold off purchasing a G80 in the hopes they'll release an "Albert Einstein Edition" G80 with IMPROVED Quantum Effects Technology and Superstring hyperthreading.

With the G80X Heisenberg, you will be very uncertain about the cost of ownership... principally, whether you actually have one or two GPUs in a one-card SLI, and even more uncertain about the electricity bill at the end of the year!!!

What is worse is not knowing that it probably worked just fine before you turned it on the first time and observed that it didn't work... you'd never know if you had a dud or not...

Wonder how the RMAs would work here...

Perhaps with the 'Pure Video' experience on their minds, they chose 'Quantum' to go with the inherent uncertainty-principle feature.

Quantum Physics Engine : <kwahn-tum fiz-ziks ehn-jin>: pronoun 1. What comes out when marketing whores without any technical background whatsoever are asked to create a name for a technology that provides advanced processing of Newtonian physics. 2. Canon fodder for DailyTech forumites.

I hope they're using the Havok API/whatever. We certainly don't need a 3rd Physics API knocking around.

Havok's good but when there's something there's always something better.

And we all want better, no?

Yes we do, we just don't want a 3rd 3rd party Physx API. What I would love to see is an open source OpenPhysx API that is accelerated on any SM3.0 card. Havok is totally unaffordable for home programmers, they won't even give you a demo version unless you are a software house. And Ageia also requires you to enter into a contract if you actually want to publish anything based on their API, not to mention the need to install another ~200 dollar hardware card into your system.

Can anyone recommend a good open source physics API that scales well to 4+ cores? I think this is the way to go for me...

RE: Havok?
By exdeath on 10/10/2006 4:10:30 PM , Rating: 2
Yeah, considering the PhysX card allows for what, 20% faster than pure CPU under heavy physics load? So throw 3 more cores in there that aren't busy running the rest of the game or OS house keeping...

oh dear

Similar to the purevideo thing eh? so it will take space on the chip but won't work until the third generation but you will see it in ads and you will already pay for it, how lovely.

RE: oh dear

Oh and plus you will need to buy the API seperately for 15 to 20 dollars, just like purevideo.

If agiea(??) cannot prove that a dedicated solution is a better solution. Then, this pretty much spells doom for the company...

I wonder if that extra memory bus and memory are for the physics(chip) on the g80.

Another marketing blunder

Quantum (quanta), noun: The smallest discrete quantity of some physical property that a system can possess (according to quantum theory).

I guess these means:

1./ Quantum Effects Technology = there is only ONE effect (singular use of quantum)
2./ It will be a VERY SMALL effect

Don't think I want one of those...

I am thinking Nvidia is going to use their UDA for this so the physics can be done to accelerate anything thrown on it. Nvidia must have done some research on this or they would not have done this. Roflcopter for this thread.
