What will Sony add to their RSX GPU development?

Hopeless pc bigot that I am, I'll be more curious to see if it turns out there are goodies in G7x we didn't know about until RSX is "official" and open.
 
Can someone post either the link to that quad core patent or the full text? Now that I have seen it, I have to read it. ;) I have been hoping that the RSX wasn't just a G70 with FlexIO, and this may be the proof!
 
leechan, I'm sorry to say that wasn't all that useful. It mostly told me stuff I already knew, or was flat-out inaccurate.

I was asking for the Sony patent that the quad core RSX pic supposedly came from. Link and/or full-text would be most appreciated from whoever can find it. ;)
 
KK ruled out eDisplay vram because 1080p needs an expensive die. Xenos must break a frame down into 3 tiles for the small daughter die and then send all the way back to the main vram with 22gb/s competing with XCPU for traffic. I would say that is not efficient for a generic engine.

PS3 should only need backward compatible 4mb edram on die as internal cache for RSX. Xenos can sound exotic but RSX is a proven GPU. :D

Horrible tradeoff, isn't it? They can keep all the framebuffer traffic within the EDRAM die, and they have to sacrifice what, 210 MB/sec, almost an entire percent of that 22GB/sec bandwith for it, the fools...
 
There are some ppl here who repeatedly claims that RSX is something different than G70(7800 series) and should be superior to that. Maybe those ppl can enlighten me, what kind of a additional features do you expect to go into RSX (which is not in G70) that makes it superior to G70? Also, please also tell me that what kind of graphics can RSX produce with those features that G70 cannot?

Well they say it has more pipes and shader power. Also the co-op with Cell makes it a bit different. Or something. :smile:
 
Yes, I'm board

My Dream!! :oops: :oops:

But why do you want put some spe in the gpu, a spe running at 550mhz should have terrible perfomance against array vertex shader pipeline with the same number of trannies.
AAron Spink have already point this

I would prefer a good implementation of tile render like in KyroII bandwidth would be no longer a probleme (as far as it is).
In fact my dream is more a full blown xenos with +300millions trannies without northbridge like logic + the same edram smart ram (as xenos) +the impressive bandwidth provide by flexIO to cell+ a tile base rendering.
AND let cell do awesome physic calculations and awesome sounds, textures decompression and other things i'm clever enought to think about.

But a beautifull things are dreams, anyways i expect the ps3 to become more and more impressive along its lifetime due to cell brute force ;)

How does tile rendering work? It only conserves fillrate, and thus bandwidth, doesn't it? I would imagine it still has to calculate the polys, even if it determines they're unseen and don't have to be filled. It seems like calculating whether a polygon is unseen would require creating it.

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!! :p

Damn. Alot of people are going to be disappointed by the PS3 when it's announced.

That's really a fucking shame too since it will be one hell of a system. I really can't stand when people ruin a console for themselves by hyping it to unrealistic levels. A multi-core GPU??? *Deleted by a Mod* please!!! I've heard it all.

Once again I have to point to my sig. Please, I warn you, don't ruin an awesome system by killing it with unrealistic expectations. Even if the PS3 has nothing more than an overclocked G70 it will still rule. I'm confident in that. Like I mentioned earlier, this thing still has to be small, produced in the millions and cost less than $500. Let's not get crazy here.

Sony wouldn't wait a year to launch PS3 if RSX is G70.

Even if they still have no games? When all you have to show at multiple trade shows are concept footage of games that just started development (or weren't even in development), you could have 5 million consoles all boxed up and ready to go and you'll still have to wait until you have a game library to launch with.

I'm sorry, but you'll have a hell of a time trying to convince me that Spiderman 2 on Blu-Ray is going to push PS3's.
 
excuse me Version i'm not very in english and for guessing cut world what do you mean by :
game ready will be 2006 marc..
i don't really understand your point in fact.

I remenber (i'm not sure..) DeanoC saying that ninja team focus their work in 720P.
i don't believe that the ps3 will output reel 1080p resolution (may be whitout fsaa and hdr)
at decent frame rate. in regard with Pc World 22gb/s to vram seems far insufficent.
Nor i expect the PS3 to provide a gap upon Xbox360 graphic quality.
But better physic simulation and environnement interaction should be a real improvement.
I think this can make game as immersive as graphic.
Graphics (for me) seems to be astounding on both plateform lol (i've start with nes euhh amstrad in fact lol)

Let me iterate my questions again:

1- What would you do with these SPEs in this configuration? or
2- What kind of effects can you achieve with those SPEs that you can not do with vertex/pixel pipelines?
