Possibilites of a "dual" GPU setup for Xbox2?

[Megadrive1988]

I think the speculation of a twin GPU/VPU Xenon comes from the technical capabilities of ATI's chips since the R300 came out in 2002 will the ability to be used in parallel. upto 256 VPUs.

I have not seen a single shred of a rumor that Xbox Next / Xenon might have dual graphics processors. although there has been speculation on the subject, including from myself, speculation does not count as rumor, imho.


I think the desire to see such a system, one with dual graphics processors, is fueling the hope to see even a rumor, which has not yet happened, afaik. not counting rumors amoug those within the industry. I am 99.9% sure there have been no public rumors about such a configuration. but if i'm wrong, then i'm wrong.

INstead of making say a 24 pipe line chip they could put in 2 12 pipe line chips or mabye even 2 16 pipeline chips in . This would allow them to spend more of the budget on shader performance and other advanced feature performance.

They probably better to go with something like Elan chip in N2, except programmable, so its like two different chips, instead of just two same chips.

There's always hope for the revolution having 2 gpus...there I started a rumor, I'm in the bizniz or something along those lines lol.

No chance. MS has been making very shrewd & cost-effective business deals/partnerships this time around. (some definitely for the better) They have basically mimicked Nintendo to the letter, in case no one noticed. No solid confirmation of backwards compatibility, no HDD, where's the earlier promised TiVo? They're preaching software over hardware, that vaunted power advantage is no longer their "selling card." They are however very aware of this. As it has always been software taking precedence over the hardware.

I cant see it

If the leaked diagram has any credence at all, the GPU is also the main memory arbiter ( as well as containing the embedded framebuffer memory ) - If 2 chips were used, how would the memory be arranged - and the connection to the main CPU(s)

Of course it's not impossible - but this is a console design.. not a high end board for a PC

No.

Sorry, but the leaked doc showed a northbridge-type chip being the memory controller, with the CPU and GPU connecting to it via separate interfaces. Two GPUs could be feasible with such an arrangement, but I would think it way too costly, and quite simply overkill from a performance standpoint. MS won't NEED dual GPUs to hit its target.

 

[Crazyace]

You are right about the NB being a seperate block on that diagram... I assume that it would be part of the gpu ( rather than a seperate chip ) seeing as the embedded dram was also shown as a seperate block.

I know speculation about Xenon derived arcade hardware is just on what some of SEGA's teams would want.

Is Sega happy with the way things have gone with Xbox/Chihiro?

... ask them.

again, there really is no reason for dual GPUs/VPUs. If MS needed to increase performance, they could probably just scale up the R500 to suite their needs, with more processing units. it would make chip yeilds worse, but probably cost less than dual-chips.

 

[psurge]

Well, not if it were impossible to scale the number of "pipes" to the desired number simply because it would require too many transistors for the process being used, and/or limit the clock speed, etc...

Still... I would be very surprised if this were the case.

While the idea of two GPU's is stupid I could just imaging it when Mr Gates annouces it next year and it has two GPU's. You would hear jaws drop with in an instant... it's unlikely, but I can dream, I think?

Poor Jaws, I'll be there to catch him.
