is MS helping with Xbox 2 graphics or is ATI doing it all?

this is something that's been on my mind for a long while, and although I've touched opon it several times, I feel its time for it to have its own thread.

what I am talking about is, Microsoft has quite a few graphics patents/IP of its own that they acquired over the years. Most notably is the 1998 acquisition of CagEnt, better known as 3DO Systems, who built the M2 platform as well as a souped up version called MX. Nintendo almost got these guys but Microsoft ended up getting them instead. they were assimilated into MS's WebTV division in 1998.

Interestingly, before Microsoft announced Xbox in March 2000, the graphics processor was going to be from GigaPixel instead of Nvidia.
At first, the Xbox was going to be based on Nvidia NV10 / GeForce256 in 1999. then GigaPixel GP4 in early 2000, then back to Nvidia at the last minute.

The GigaPixel engineers had been moved into I think the WebTV division at MS. to stretch things a little bit, I think its safe to assume the GigaPixel guys could or were mingling with the CagEnt / 3DO Systems people. why not right? If Nvidia had not been selected, Xbox would've been GigaPixel GP4 based, with perhaps some assistance from the 3DO engineers. In the end of course, Nvidia made the Xbox GPU by themselves AFAIK. Microsoft's only contribution was funding and the specs they wanted. I doubt MS people actually helped Nvidia since NV2A was basicly a custom NV20/NV25.

now fast forward to 2002-2003, where ATI is working on the graphics for the next Xbox. the main design location for Xbox 2 graphics is said to be ATI's east cost Marlborough design center. yet it was also revealed by ATI's Dave Orton that R600 is basicly a joint effort by all of ATI's design centers, with west coast and orlando included. see the recent interview with Dave Orton....

yet there have been persistant reports that Microsoft was wanting to design its own CPU and GPU for Xbox 2. could it be that this time, Microsoft is working closely with the GPU designer on the architecture? why waste the resources Microsoft has in IP/patents and engineers. could it be possible that Microsoft sent their best graphics people to Marlborough to help work on Xbox 2 graphics? or some other senario in which these MS graphics engineers help out. If ATI can coordinate development of a graphics processor across all of its design centers, why not with Microsoft as well. over their networks or the internet or whatever.
 
don't see it happening. ati will want to use all the tech in future gpus so they wont stumble like nvidia did .

The chip going into the xbox 2 will be a bit from whatever the other 2 teams are doing and some other things that the 3rd team is doing .

THus they save money , resources and time.

does this mean that Ati will be privy to future DX specs earlier than nvidia:?: Perhaps, Ati will have better future hardware than nvidia due to more experience with the api....or am I talking nonsense :oops: :D

It just seems to me that Ati is getting a head start on next gen hardware versus nvidia; they'll be making a VPU fully compliant with XNA (it's supposed to be the next DX or something, right? I read that in one of the Allard interviews I think)....XNA also includes PC's so game devs looking to make decent quick ports should be looking at ati hardware then.

(if whatever I say, sounds like garbage, it probably is ;) )

on a side note...is it better (cost-wise or physically) to have a ridiculous amount of pixel pipelines to achieve a high fillrate or to have a high clock speed to achieve the same fillrate?

and... does not including opengl support mean a smaller graphics chip? (I'm not sure how API support translates to physical hardware, btw)
 
I believe GigaPixel was bought by 3dfx shortly after Microsoft announced the Xbox deal with Nvidia. I do think that some GigaPixel engineers did work out of WebTV's offices prior to being bought. It was also said that Microsoft was still planning on investing in GigaPixel after the buyout, but I never heard what happened. Who knows what happened, especially after Nvidia getting 3Dfx and GigaPixel.

I was under the impresssion that one of the reasons why MS choose ATI is because ATI's future designs where in line with Microsofts graphics philosphy. Also, someone here had a thread linking to an article in MIT's Technology magazine concerning Microsoft's Bejieng (sic) lab. That article implied that the lab, apparently famous for its graphics work, was involved in Xbox/Xbox2 design work. And considering the fact that the Xenon's schematics were leaked on a Chinese website, doesn't it seem likely that MS is in fact contributing a great deal to the GPU or overall design?
 
Um, why would Microsoft want 5 - 10 year old (and incompatible) technology in their sexy new console? If you are referring to the engineering talent, I have a feeling they've all moved on since, and if they haven't, their skill set definitely wouldn't be current (or even comparable to a bleeding edge company like ATI).
 
MS have some of the top graphics talent in the world. They are the bleeding edge of graphics research, far more than both ATI and NVIDIA put together.

Of course its mainly software rather than hardware but I can't imagine they had no input at all.

thanks Deano - glad someone understood my point of view.
 
IIRC MS is "just" licensing the IP from ATI, so maybe they (MS) can custom the VPU... MS could work closely with ATI and give them some tech (that they own via patent) to implement in the design of the XVPU.
A custom R400 (or a.k.a 600) that contains some MS proprietary tech is not a crazy idea, since ATI would still own a "simple" R600 that they could use for theirs PC VPU.
 
"Microsoft Research is by far the biggest contributor to graphics in the corporate world. It’s a powerhouse," says Paul Debevec, a graphics expert at the University of Southern California’s Institute for Creative Technologies. "The Beijing lab, in particular, has achieved “some amazing resultsâ€￾

exactly one of the senarios I had in mind. 8)
 
the more custom the X2'VPU is, the less games will look like PC games, in theory anyway. Xbox suffers from this to some degree, although there are very unique looking games like Panzer Dragoon Orta.

I hope Xenon can keep its technical superiority over highend PCs longer than Xbox did. everything so far is pointing in that direction (3x PowerPC CPUs, on-chip VPU memory, unique features in VPU, etc.)
 
Well, it certainly seems more flexible with the PS3.0+ or whatever, and console devs always exploit quite a bit from the hardware anyhow. Doom 3 on xbox is a surprise to me ;) Well, Chronicles of Riddick was the bigger surprise in that it's running at very good frame rates using D3-like tech.

It won't hold against the highest end hardware, but it'll hold it's own against a huge majority of what most consumers will have anyhow at Xenon's release IMO.

Say bitboys?

Or software, you mean just like game designers?(except for only dealing with concepts?) Well, from any aspect you'd approach it, micosoft would have some of the top graphics talent in the world, but even xgi fits into that ranking.

He means fundemental research into rendering algorithms.

For directx, or just random research that has yet to be applied?

Random research, some of the areas they work on is here http://research.microsoft.com/research/detail.aspx?id=8

You can find some of the true greats including Blinn, Loop and Cohen hanging about there.

In recent time PPS (Peter Pike Sloan) did a fair bit of PRT research here. The internet graphics (wrong name IMO) also does some good real-time research including one of my favorites "Realistic and Efficient Rendering of Free-form Knitwear". So the next time you see a hero wearing a nicely rendered jumper you will know who did the research :)

If your interested at the cutting edge of just about any computing subject, http://research.microsoft.com is a great place to start.

Some of the stuff has made it into DirectX. Not everything they do is pie-in-the-sky research.

I think the progressive meshing stuff in DX is related to something that came out of MS Graphics Research.

Some of the PRT stuff is definitely going in. I think Tim Sweeney is already planning on using it for the Unreal Engine 3.0.
 
I'd like to see all of Microsoft's and ATI's combined research pays big dividends for Xenon. all of that research isnt just for research sake, but to be applied for buisness.

agh that did not come out exactly the way I wanted it to, but you probably can understand it anyways :)
 
That article posted above indicates MS Beijing Lab has a hand in the design of Xenon.

But in fact, a better Xbox is ultimately part of the lab’s mission. Reminders that this is a business, not a researcher’s playground, are never far away. In an adjoining hallway, a large corner room has its windows plastered over with opaque sheets of paper. The sign on the locked door reads, “Xbox: Confidential.†Baining Guo, a former Intel researcher and now Microsoft Research Asia’s graphics research manager, isn’t allowed to talk about what’s going on inside. “Some of our best people work in there,†is all he’ll say.
