What will Sony add to their RSX GPU development?

[Bad_Boy]

I'm guessing here,

What would we call a GPU with multiply cores....

What if each core of cell had it own GPU core to work with?

and we had two SPE for one GPU core?

I dunno about you, but I'd call that very impressive and very expensive?

No it won't cost that much over PS3's lifecycle. Sony is building PS3 with Ten Years in mind. They make their only chips in their own factories with their own CE products. Think about how much it must cost them to make the EE/GS right now... They could even put an EE/GS in PS3 for B/C without adding too much more to PS3 cost.

You can't just strap these things together with a bit of tape.

Even assuming PS3 has the best possible chip designs ever, it would take more than double the power to still have a competitive design in 10 years. A year from the launch of the ps3, the same power could be had for half the price. 2 years after that, the power could be had for a quarter of the price. Even if they just do some kind of sli, they could make 4 ps3's (hey, cell is meant to connect with others and the gpu does have sli as an option) and hook them together in a mere 3 years from the launch of the ps3 and have 4x the power.

BTW, on a side note, how come people think cell will meet its lofty performance goals, when previous attempts at a "more powerful than ever chip," such as itanium, have come nowhere close? Are the guys at IBM and Sony really so much better than the ones at Intel that they were able to design a paradigm changing chip, while Intel can barely design one that's competitive to its far older product line? Why is Cell > EPIC?

Ten year lifecycle doesn't mean ten year before next console is made. It means that this generation impact will fully realized over the next ten years.

Reading between the Lines...?

SPEs represent the first implementation of a new processor architecture designed to accelerate media and streaming workloads. Optimized for power efficiency and area, the

http://www.beyond3d.com/forum/images/smilies/icon_arrow.gif
Icon ArrowSPEs are well suited for multicore implementations that can take advantage of parallelism.

Load and store instructions for the SPEs are performed within a local address space served by a Local Store (LS) memory (256 kbytes) that's attached to each SPE. A 128-bit data bus (16 byte) connects the LS memory to each SPE.

Also in development for the PS3 is an advanced graphics processor that Nvidia is basing on its GeForce 7800 GTX architecture.

Icon ArrowDubbed the RSX Reality Synthesizer, it can perform 136 shader operations per second with its multiple programmable shading processors.

Pixel resolution will be 128 bits for exceptional image creation and dynamic range. Furthermore, the chip will deliver a screen resolution of 2k by 1k pixels-the highest high-definition video resolution defined by the HD standard.

So what are the strengths of the Cell compared to all other architectures (since there seem to be only maybe 2 other major camps of design) and what are its weaknesses?

 

[leechan25]

Cell has SPE that can handle different task simultaneously...

I think the RSX has multiple programmable shading processors.... (kinda like PS2 vector's)

I'm not really sure of how many of these processors RSX has but i'm guessing 4.

Maybe there could be a two SPE setup per GPU core?

Maybe a developer can opt to use 25% 50% 75% or 100% of cell & RSX processing power. just guessing...

Remember this is all just guessing but that what the thread is for!

 

[version]

4 or 8 processzormodule but 1 for redundancy, 1 module working with 4*4 pixel in parallel with 16 simd units

 

[leechan25]

Version,

you sure started a firestorm in me!

"4 or 8 processzormodule but 1 for redundancy, 1 module working with 4*4 pixel in parallel with 16 simd units"

really? wow.

The true truth: Version and Mr Kutaragi are the same person!
Mr Kutaragi is a bit frustrated cause they don't let him put all the features
he wanted in PS3 GPU..so he comes here to write about his tecnology dreams

 

[leechan25]

Well this is the place to do just that! nAo you know something that it seem we have to wait for. However, can't you comfirm or deny any thing that has been written here? I already know RSX is going to have more than one core ... or maybe I don't...

BUT YOU DO!

version has to be the best poster on B3D. Not really for information but for comedic relief .

Unless.....

 

[Thegameman]

that's nearly a year old quote, talk about reaching.

Yes is almost a year quote,but how does that change the fact that the G70 was tap out ages ago and the RSX hasn't,hell Nvidia already has a 550 Mhz GPU out there.


It din't take them that long to make the xbox one,which was also a modified one,by the time of this interview they had 18 months working with Sony,i wonder why it take so long.

there's a lot of talk about RSX being a multi core GPU...now I can't wait till jenuary the 5th just hope to know everything...

 

[overclocked]

Thinking about it and hearing whats been said in the game-stores by the "wise" sales people to harmless moms and kids. THE biggest suprise to all i think is " We announce the worldwide PS3 launch on 31 march!". Maybe..

well thats the only way the difference in performance between PS3 and XBOX360 Sony is thyping about can be explained
They made the PS3 seem like PS4 at E3 and that XBOX360 was really an XBOX1.5.
Such a difference between generations is crazy!!Only if they have a hardware secret that makes PS3 have superb unexpected performance can exmplain this.

Otherwise they were bullshitting us!

SOME OF YOU DEVELOPERS PM ME SOMETHING!I KNOW YOU KNOW THINGS!!SCREW NDA!!GIVE ME DA INFO!!

nAo, tell us nOw....:smile:

 

[Guilty Bystander]

Like is being said here before.
I think we could be seeing a G70-71 with perhaps 2 or 4 SPE's of it's own.
