RSX in the same league as Quad SLI?

[Slay]

This is from ps3-live and here is the Google Transation.

The Gametrailers site diffuses it video of the interview of Derek Perez , in addition to-Atlantic representative of NVIDIA , carried out at the time of THESE , in which it presents the Quad-SLI technology , which consists, in short, to combine together four graphics boards NVidia in a PC, in order to obtain maximum graphic performances.

The characteristics obtained by this technology are as follows:

. 1,3 million transistors
. 41 Gigapixels/seconde
. 96 pixel pipes
. 2Go of graphic memory
. 5,2 TFlops of total power


According to Perez and its assistants, this technology makes it possible to push all the details of a play to the maximum: resolution, effects special, etc... without testing the least deceleration. Two plays are presented to propose this technology: The Lord Of The Rings: The Battle For the Earth Of Medium 2 , and Dungeon & Online Dragons .

And always according to Perez , this technology "makes it possible to the players to have an idea of the quality which will be realizable on the PS3" , via chip developed by NVidia , the RSX .

Uhm no. Unless u're talking about quad 5900 (or something) SLI if such a thing existed.

No way in hell.

I can't reall see even the most fanatic of PC gamers getting four cards for his PC, really what is the market for such a thing?...

Oh please, there will ALWAYS be some loaded super geek who just loves to splash out his money of vastly useless hardware like this. I would bet this 4 SLI configuration doesn't even come close to 4X the performance of a single card. But there are lots of people out there with lots of cash to throw away...

 

[AlNom]

I would bet this 4 SLI configuration doesn't even come close to 4X the performance of a single card.

Well, maybe at 2048x1536 + 32xAA.

 

[London Geezer]

Well, maybe at 2048x1536 + 32xAA.

You just KNOW that even with 4 cards, somewhere, somehow you'll get slowdown with those settings...

 

[sir doris]

Tomshardware had a preview (/w some benchmarks) of 2x Dual SLI 7900GT cards in a quad SLi configuration.

 

[Shifty Geezer]

Love the translation!

The Lord Of The Rings: The Battle For the Earth Of Medium 2

I missed 'LOTR:The Battle For the Earth Medium' number one. Was it any good?

4 GTX's in SLI = boondoggle

And always according to Perez , this technology "makes it possible to the players to have an idea of the quality which will be realizable on the PS3" , via chip developed by NVidia , the RSX

Could RSX be multi-core G70s or something of the sort?

Or is he just refering to the improvements of a custom designed chip for the PS3.

Speng.

 

[Carl B]

I think he's just talking about comparable visuals - nothing more, nothing less.

Of course I just think it was an off-the-cuff comment that actually doesn't mean much of anything.

 

[AlNom]

Or is he just refering to the improvements of a custom designed chip for the PS3.

Perhaps this, but I think it's more the fact that PS3-only developers will actually target and optimize for the hardware more than devs on PC would for a single PC video card.

Quad SLI is by using 2 GPU's on one card and then applying a card with SLI, isn't it?

Not in Dell's implementation it's not. But Asus does have something like that going on it seems.

 

[j^aws]

A cost/ performance argument could be made for a dual GPU design ( 2 dies) against a single GPU ( 1 die), for certain configs. E.g. dual 6 VS/ 16 PS/ 8 ROP GPUs maybe cheaper cost/ performance than a single 12 VS/ 32 PS/ 16 ROP GPU.

Conversely Xenos parent/ daughter dies follow a similar cost/ performance curve. And having two 'identical' GPUs may make the curve cheaper. IIRC, the PC Engine SuperGrafx also had twin GPUs (well twin rasterizers), so it's nothing new in consoles...

 

[Shifty Geezer]

Could RSX be multi-core G70s or something of the sort?

No, no and no. That would be an insanely large and costly chip. Insanely. Could a multicore G70 actually be fabricated without defects? You'd be looking at 600+ million transistors

It's a matter of optimising a cost/ performance curve. See my reply above, it's not totally unfeasible...

Not to mention the power requirements...

What's the powersupply requirement for SLI right now, about 450w? What about quad SLI maybe 550w? Can anyone see a PS3 with a 450w power brick?

Hypothetical birdie

* NVIDIA G80 based core (Main Setup Engine)
* 4 Sony (mostly Toshiba IP) specific co-graphic engines
* 4MB Cache (routines, load balancing, quick swap, ECT…)
* 400+ Million Transistor count
* 60-87 °C (Idle/Gaming)
* 84.3W power consumption (GPU alone)
