ATI's physics goes on the back burner

During ATI's 2006 third quarter financial results conference call this morning, ATI CEO Dave Orton revealed to analysts that despite demonstrating physics processing earlier this year, volume availability will not be for another "9 to 12 months." Orton indicated that the technology was still undergoing testing and preparation. Interestingly,  ATI indicated earlier that its physics technology was already on the market and needed only driver updates.

DailyTech has attempted to test some physics-enabled demos on a pair of Radeon X1900 XTX boards but drivers were not ready. Interestingly, ATI demonstrated physics on its RD600 chipset at Computex earlier this year but a year from now, ATI's RD600 will more than likely be phased out. In fact, ATI said during the call that it was already developing and testing RD700, its next generation core logic.

After ATI's announcement about its own physics solution during Computex, AGEIA responded by indicating that ATI's method was crude and did not really address the core needs of physics processing. AGEIA also indicated that its own widely accepted technology was already available on store shelves. AGEIA's availability argument was somewhat called upon by ATI customers, citing that ATI too had boards already in the market. Orton's announcement today unfortunately reaffirms AGEIA's point. Many ATI customers will have to wait a while longer.

Details on ATI's R600 core -- the replacement for its X1900 family -- is expected to be available late this year or in early 2007. It is unclear whether or not ATI's physics API will continue to support the X1900 family a year out from now.

Update 06/30/2006
:  We earlier reported that "retail availability" was not to be available for 9-12 months.  Instead, Orton's exact meaning was for "volume availability," and as such DailyTech has changed the article text. Will Willis, Senior PR manager for ATI sent us the following comment about ATI's physics solution:
Dave’s reply was that we won’t see physics in volume (i.e. hundreds of thousands of cards being used for physics) and therefore a material revenue stream from physics for 9-12 months (i.e. another 3-4 quarters) as that’s when there will be some substantial volume of ATI graphics cards being used for physics purposes.

ATI GPU’s that support physics acceleration are already in retail (i.e. the X1900 and X1600 series of cards for example).  All that’s required is a driver update that enables physics processing, and more importantly, game content which we expect around the holidays.  We’re very likely to see revenue from physics before 9-12 months, but as Dave said it won’t be in volume, it will likely be early adopters.
Willis claims content for ATI physics will be available this holiday season already.  However, there is no word yet on the driver other than it is "several weeks out."

PhysX is suffering the same fate that killed off the Kyro series of chips (remember when everyone salivated over these "ATI/nVidia killers"?) which is lack of good support. With the first game showcasing PhysX being at best ho-hum performance benefits you wont be getting people to line up in stores over this. In a similar vein I remember how the Kyro II would be twice as fast as a Geforce 2 MX (its competition) in Quake 3 but in just about every other game there were massive bugs or it ran incredibly slowly.

Perhaps its not thier fault because they are not developing the games but at the same time its not helping thier situation the games available to use it dont really use it well.

A comparison with S3 Savage would be just as good. S3 had more technologically advanced chips, but they were hampered with poor drivers and slow memory.

You've GOT to be kidding!?! S3 and Kyro having more advanced chips? Not even close! S3 was the first with texture compression (I think), but other than that they made no contributions at all to graphics).

Those guys were trying to fight Nvidia and ATi's LOW end cards. And what's the point in that? Even someone going for a low end card is better off buying from a brand with proven drivers.

But...yeah...chicken and egg problem for that physics card. We don't even have proof that it's better than a CPU or GPU doing nothing that physics, but even if it is, it won't be used to change GAMEPLAY until almost everyone has one, and that won't happen until it's used to enhance gameplay. Don't know how they thought they could get around that issue.

Oh well this is kinda disappointing though as I was hoping it would lit a fire under AGEIA's arse to make a competitive/performance part with options in the driver set to IDK say not compromise system performance just for a few extra moving crates.

Either way though ATI's solution does have some fans simply because the prospect of using older model cards when you upgrade to do physic work is tempting.

Pure Speculation: ATi is probably going to support Microsoft's DirectPhysics. Ageia is banking on their own PhysX engine. nVidia is supporting HavokFX. Havok 4.0 is apparently a winner with great use of dual/multi-core CPUs. ATi and DirectPhysics might be a winner.

Personally, I have this feeling that DirectPhysics will become the defacto standard and ATi is probably waiting to see how that works out. I just hope this doesn't inspire nVidia to deliver a rushed product to 'capitalize on the situation by launching a product that will serve no purpose'.

Then again, this whole PPU concept makes me mad. Isn't this what multi-core CPUs were gonna be used for (from a gaming perspective)? Are 10 times more flying crates/bouncing sparks really worth a dedicated processing unit? I seriously hope this whole concept fades away and developers decide to support multi-core CPUs.

Microsoft has never actually said they are creating a physics API. For all we know they might have been covering their bases with that job posting, or they could still be looking for someone to fill it. Even if they are working on it, it will be at least 3 months after the leak that Microsoft confirms it, and at least a year before cards that support it start to ship. ATI is not going to put its cards on hold for the Microsoft API.

As I have said before, PPU and GPUs are a large number of cores on one die. For example, x1900s are 64 cores in 4 core groups (for the 1:3 pipeline ratios). Most multi core processors are dual core (2 cores), with at least one reserved for the main game code, and the other partially used by system resources to manage data transfers etc (unless they game is properly threaded, in which case all cores are going to be pushing the game engine). In most cases you will not have sufficient CPU power left to quickly process a large number of dependent calculations necessary for complete physics.

Conroe and the K8L should roughly double the vector throughput per clock of the K8, single threaded. Add to this quad core and you have another 4x. That works out to an 8 fold increase over the current single core, A64/P4 generation, assuming no clock speed increases. Couple with large caches, lightening fast access to system memory and single digit latency for interprocess communication, I think this will more then give dedicated PPUs a run for their money.

The biggest issue though is going to be the bus. I don't know how fast Ageia's future PCI-E cards will be, but thats going to seriously limit the range of problems they can be applied to because at a certain point its just faster to let a local core do it then wait hundreds to thousands of clock cycles for a PCI-E device to do it.

Reading the reviews of the Ageia PPU I start to think that quadcore processors, more cache, and better system performance overall might actually manage to make a PPU worth it! As it is now they're horribly bottlenecked by current systems. I'm sure the coding will get better, but if you think about it all these dependent and related calculations - they must start to bump up overhead.

Just my opinion, but PPU's will come in (Come on, they make way more sense then spending ~$1000 for 2 VGA's!) - The real question is if they'll be intigrated into some other component or will systems get so fast processors can just handle it. I would wager intigration in the mid-run. I'm sure everyone's happy to let Ageia be the 'front-guard' here.

I don't think you understand what a PPU does. It offloads functions from the system. The system doesn't bottleneck the PPU since you're not interested in PPU performance, but rather are interested in overall system performance. What actually happens is the faster the system gets (particularly in vector performance), the less interesting a PPU gets simply because you don't get such a large advatage from offloading things. As more and more cores become available, the utility of coprocessors in general will drop.

Actually Ageia has stated in interviews that they will support a unified physics API if someone makes one, this is the same way 3dfx operated, by having their own proprietary API (Glide) and then supporting other APIs (OpenGL, Direct3D). It's really just a matter of Ageia making drivers for DirectPhysics, and they'd be pretty stupid not to. This would be a win-win situation for everyone, as customers would be able to choose between Ati/Nvidia's (Nvidia would also be stupid not to support DirectPhysics) GPU physics, Ageia's PPU or multicore. Then we could also finally see which solution is the fastest.

Correct me if I'm wrong, but wasn't there an article either here or on Tom's Hardware/Anandtech that stated that both ATI and nVidia were working closely with Havok for their physics implementations? So AGEIA is the only one with the truly proprietary system (made in-house). Microsoft will undoubtedly work with Havok (or who knows, maybe aquire them ;-) for their DirectX Physics implementation (which was announced a few days ago, I believe).

Personally, I question the need for dedicated PPUs (Physics Processing Units). Looking back in the industry, what has come out as a significantly successful technology tends to be good for more than just games. Most physics processing in the business/science world are done by CPUs/supercomputers made for the job. I do not anticipate this technology becoming useful/succesful in any other application than gaming. Unlike graphics accelleration/OpenGL (speaking of which, where is OpenPhysics in all of this?) which was used VERY heavily in workstation graphics processing, etc. before and after games began to take advantage of the system, PPUs started, and perhaps are going to be used exclusively in the game industry. Not a formula for success, in my opinion.

In short, I agree with your comment. Perhaps a better solution is to create a standard physics engine (DirectX Physics/OpenPhysics) that takes advantage of Multi-core CPU hardware for physics accelleration in software - similar to what Havok has already started for software-based physics. I don't think a few extra sparks and randomly-bouncing crate explosions are worth $150+.

You're right, of course... it is/will be called OpenPL (Open Physics Library) if that standard becomes a reality. I was simply making reference to it's Open Source nature w/o acronyms for the sake of clarity. Actually, I recall running accross an "OpenPL" project not too long ago (shortly after AGEIA was released). If I remember correctly it was an MIT project. Doing a quick Google search just now didn't reveal anything, but who knows?

As far i can see, the majority of you guys are complaining about Physics in general. Why complain over EVERYTHING, if you dont agree with physics, here's an answer, dont but the f---ing card, dont worry what NVIDIA and ATi are doing, who cares you arent interested right, so quit all your b----ing and dont buy anything.

To use a dual core CPU to process physics is great, most games dont even run any better with dual core CPU's anyway. who needs 2 3.0 CPUs to run Half-Life 2 or F.E.A.R.??? Nobody, if you think you do then you are an idiot.

true but lets not forget that dual core has other applications, i could encode and burn something to dvd with one core and play a game with another (i also have three seperate HDD's for different uses and im sure 2GB of RAM would be enough for both purposes).

Not to mention you could have one core take care of the crap running behind the game (windows and such) and have one core completely and utterly to the game. With the X2's and their seperate caches (linked by the very fast HTT links) you can easily have both cores doing completely different tasks with very little impact on either task.

Physics cards right now are useless. They add eye-candy and no more (they even slow down the games while producing that eye-candy), plus considering they can't be used for online competitive play (since people without the card will see something completely different to ones that do). In the end utilizing graphics cards as virtual physics cards is going to be the winner, they use the fastest possible interconnect (PCI-Express x16) and have much lower latency then PCI. Graphics cards themselves are pretty well built for processing graphics, all that is required is new drivers to take advatange of the GPU and a game written with the new Havok API with ATi and Nvidia support (future tentative title :P).

However i must end this post because i have begun to wander (someways back) and i might end up on some completely different subject.

You could already do this provided you had one CPU that was fast enough. Adding 2 cores doesn't change the equation at all. You could have 2 cores devoted to the game, and then let an encoder share them with the game, or you could have the game not be multithreaded. Either way you can still do both at once, so its not like most people are going to care.

Theres no performance advantage to doing this though (since you can't really dedicate any core entirely to one thing on a PMT OS like Windows, Linux or MacOS), so I don't see why anyone would. If there was a performance advantage, the X2 crush the equivilent 64 or single core FX. But they're essentially identical.

I agree with your remarks about GPUs. If you look at the stuff MS, Ati and Nvidia are talking about for the next 5 years, GPUs start to look a lot like PPUs for many applications. Not quite as good a solution, but probably 80% of the way there, and dual and quad core are likely to pick up the remaining slack.

Dude, nobody is here is complaining about the advancement of technology. Everybody WANTS great new technology to come out AND offer a consistent and long-term solution for all parties involved - consumers and developers as well.

Look at high-end audio: DVD-A/SACD both offered remarkably better technology for both consumers (increased fidelity and extras) and labels (better DRM). All they had to do was up the production of more albums and CD would have been on its way out today. But nobody liked the idea of two formats: CD still reigns supreme and the RIAA is still crying hoarse. Those who spent big bucks on upgrading their sound-systems now feel burned over the lack of new discs to play on their setups.

BluRay/HD-DVD is going the same route, some say.

Physics in 3D gaming might die and be a has-been if there is no uniform way to implement it. What a lot of people agree with, is a $300 expansion card for some sparks/explosion effects as in GRAW isn't going to justify their hard-earned money. I wasn't aware that Ageia has promised to support any new standard-APIs if they become available - this is a good step. People just want to be able to enjoy their games with the price/performance hardware of their choice: ATi, nVidia, Ageia or a multi-core Intel/AMD CPU. But it shouldn't mean they are locked out of features themselves.

A PPU should make things faster and deliver higher frame-rates...a general-purpose multi-core CPU should still be able to handle it but at a relative performance hit. Just the way it works in the single/dual GPU world. Currently, PhysX doesn't exactly offload tasks from the CPU to take your FPS from 25 to 35...it just calculates some superflous effects.

I understand that HLSL/SM 3.0 instructions that can be executed on GPUs offer higher performance advantages over CPUs for physics processing. Let's just say I was wishfully hoping that mutli-core would be the way of the future...maybe I am wrong. So I know a PPU will be inevitable in the future.

The main point is consumers DON'T want to be locked out of a major chunk of games that may/will not support the hardware they have. Why should I have to make a compromise whether I want Ageia for Unreal 3 or HavokFX for Source-powered games (or whatever) or DirectPhysics for Alan Wake/Halo 3 or whatever?

Unfortunately, since PhysX is already here...ATi/nVidia will want to capture a bit of the market - good that ATi is backing down. Otherwise, this usually means rushed-to-the-market products that have short shelf-lives and buggy support. The idea is out there...the developments will arrive...and like you said, if I don't like it, I don't HAVE to buy the f---ing card. That's not the point: the point is, I WANT to buy a f---ing card BUT when it is done right.

-- ATI Claims No Physics for "9 to 12 Months" --

All I can say is it's about time someone stood up and made a forthright decision about these sorts of things.

I for one have long since become completely fed up about physics.

So ATI ought to be applauded for doing something about this scandal that has been going on now for about 8.5 billion years.

Physics, as I'm sure everyone will agree, has gotten completely out of hand. It's not just gravity and quantum electro-thermo dynamics that stick in our collective craw, obviously enough, but the laws of motion too, along with relativity theory and other assorted forms of foolishness.

But at last the brave folks at ATI has declared a moratorium on the madness. "No Physics for 9 to 12 Months," says the headline, and so we can all breathe easier for awhile, at least.

Now if only a few courageous souls at Intel or Microsoft would step up to the plate, shoulder their responsibilities, and cancel the laws of chemistry, then things would REALLY start improving!

The ATI solution IS dedicated, the 3rd card is used PURELY for physics. And physics itself is just a bunch of calculations, so the computation power of the PPU will be the deterimining factor of physics acceleration. With parrallel processing available on the red hardware, it'll be an effective solution.

As for game support, it's all about who's API game developer will choose. UT2K7 has chosen the AGEIA API, other titles has chosen Havok's API (which NVIDIA/ATI supports), and there are still independent API that Crysis will use. I don't know about you, but I'm looking forward to Crysis more than UT2K7. Going the AGEIA way wouldn't work in the game making the $300 card useless. At least with the ATI way, users will only be using their "old" x1k cards or spending $100-150 on a X1600Pro or XT as the physics card.

If future games end up to be like the performance of GRAW, (yes performance has been increased now), that only means end-users will be depended on AGEIA to come out with new drivers and patches for every new game out there.

The way I see it, it's going to be a battle of API support, whoever has the widest support will win. Between AGEIA, ATI, and NVIDIA, whoever can support the most API will make them most widely adaopted. At Computex, ATI has told the press they are looking to support more than just the Havok API. AGEIA on the other hand is just planning to support their own. It'll be a battle for a year or two until MS comes out with a standard DirectPhysics.

No it is NOT.

The three cards (in ATI's solution), are still video cards. What the driver does, is assign one of them for physics. That's all. It is NOT a REAL physics card.

You can have two video cards and using the same physics capable driver, to "load balance" the calculations between physics and 3D/video calculations on both cards.

Either way, its not a full blown dedicated physics solution.

Having a video card that is assigned for physics is not as optimal as having a card that is designed from the ground up to do physics. Its like getting a programmable high speed processor ($20k) for 3D work instead of buying a GPU based solution. Yes, it can do the work, but its not gonna be optimal for the assigned purpose.

ATI/Nvidia's solutions are cost effective (to some extent) and are quicker to get to the market. But they DO NOT cover all physics features like the AEGIA solution. Go compare what the AEGIA solution can do, and what the ATI/Nvidia solutions can do, and you'll see its quite different in the types of physics they offer. This is what MANY people don't get. Just because they say it does physics, doesn't mean its all the same physics. (Rigid body, liquid flow, etc)...Go read an article done by ArsTechnica and you'll see that even the Havoc approach does NOT bring the same level of stuff as AEGIA's solution.

Its a quicker way to get there, but its not necessarily the best way.

That's the point I'm trying to make. Having a pseudo-physics solution is NOT the same as having a REAL physics solution.

After ATi created massive uproar about their own Physics processing, I'm betting that it had an impact on not only Aegia(and their progress, as competition tends to do), but also sent a signal to game developers that Physics is something to get serious about. But now that it will be nearly another year before we can expect physics processing from ATI, who do you think the market/industry is going to begin to accept?

I mean, look at Crossfire. It was slow and steady, and now practically representing a very minute number of the people who actually own a multi_GPU solution. If ATi's physics approach takes the same route, I'm betting Aegia will prosper nicely at ATi's expense (for a.)not being able to deliver on time and b.)creating uproar about physics processing - kind of like their own marketing for Aegia, which I'm sure Aegia is now appreciating.)

The main reason I think that you're wrong is quite simple...how many games out there actually make use of physics right now?

For all you know, DirectPhysics might be an adaption of the Ageia PhysX SDK into DirectX. The PhysX SDK works with or without a physics accelerator so it would be a good choice for Microsoft. Also, If any of you have used the Microsoft Robotics Studio, you will know that Microsoft chose the Ageia PhysX Physics Engine for their robotics simulation program. Also, if DirectPhysics was to implement the PhysX SDK, then that would unify the Physics Acceleration model, because then everyone could use DirectPhysics with any form of physics acceleration (no hardware/PhysX/NVIDIA&ATI through HavokFX). And since HavokFX will most likely be engineered to work with DirectPhysics that will allow all hardware-accelerated physics engines to be able to use any physics accelerator and still recieve benefits. This will overall cause physics acceleration to be widely accepted much quicker.

It would be nice if MS would take it a step further and make a DirectParallelProcessing or more generic than just physics. That way general business or scientific applications could take advantage of the big parallel performance numbers you get from these types of processors. It could be used for recalculating spread sheets or various scientific calculations.

I remember reading something about someone using a new GeForce card to make an awesome sort routine, that was massively faster than a regular CPU, by using all of the parallel processing available in a GPU.

Everyone has misinterpreted ATi's statement, it is saying that ATi does not believe it is likely they will see a large number of sales of their pre-existing graphics cards due to to physics processing. This does not mean that ATi is delaying physics in any way, it simply states that ATi does not believe there will be market adoption of this feature, at least not in any noticable volume, for another 9-12 months. News blurbs on this all come off as very negative, until you read ATi's quote, with the way people read news now, im sure you'll have a few thousand ADD news readers that now believe ATi has dropped the ball.

To put it simply, all ATi is saying is that they will have the physics processing available, for everyone, and soon, but they don't think anyone will buy the extra graphics cards for another 9-12 months. How has everyone misinterpreted this so badly...




Go for a MoBo

Ageia simply needs to get their chip set on a MoBo. If they can do that, bringing there solution to a greater segment of the market is much easier.




That's a shame

I have to agree with the comments posted above me. After all the hype about how much better ATI's physics processor was going to be I was looking forward to giving it a test run. all my systems at home have ATI cards. This gives Nvidia another chance to beat them to the punch. You definitely do not want to be the last kid on the block with the new Jordans in the graphics card industry. They have been taking a pounding all year from Nvidia across the board. after struggling so hard to get even again (and in a lot of areas just sucking wind behind them)it would be a shame to see them fall back again.




dx10

Looking at the specs for dx10 it seems likely that a dx10 based card will be able to handle physics significantly easier (and faster) then a dx9 card, the added programmability should really make a difference (and the time frame ati just said is about right). They may have realized the difference the new hardware would make and decided to wait till it is available and release something that actually shows a major improvement vs. the comparatively smaller one they would get now (another year also gives developers more time to start to adapt engines for it, though a year isn’t that long from a development point of view).




hmmm.

Maybe ATI is going to buy Ageia.




Not Quite

Well, He didn't say "retail availability". What he said was, "Now it is really from a volume standpoint we say it its maybe nine to 12 months out. . ."

Which isn't quite the same thing. It appeared to me he was pointing at when having that ability starts selling signficant numbers of new cards. But it does sound like there's an event in there he's looking at for 9-12 months out. . maybe the first games leveraging it?
