RSX still in development, no silicon produced yet.

RSX technology at E3 wasn't exactly RSX, but what it "should be".

Burkett discussed how NVIDIA and Sony had used an upcoming product with many similar capabilities to the RSX to demonstrate the capabilities of the Playstation 3 GPU. The demos at the show were running on NVIDIA's upcoming high-end desktop part, and also SLI systems. It is unclear whether these were based on the new desktop part that we've referred to as G70 in the past, or whether they were GeForce 6800 Ultra SLI combinations

This could be good news or bad news depending on how you look at it. Most of what Sony demonstrated were based on projections and theories.

That's news? All the realtime demos were only showing off Cell anyway...
Apart from the subsurface scattering one, which could be done on high end GPUs out today.

I don't think there was XBox360 hardware at E3 either and their release date is a lot closer.

With all the noise on the forums I can't even remember which PS3 "RSX" demos were real-time. But if they were running in G70 it may be a good sign for the PC space.

In what sense was Epic's Unreal demo not realtime, or only showing off Cell?

Hmm, from the Sony conference and the way they presented things, I thought they were running on early silicon of RSX.

Unreal 2k7 in realtime on RSX and Cell, would indicate that it's running on the system. However, it appears it's running on RSX type technology which is included in the G70.

Much different than what I thought.

there was one final 360 hardware at the show running at the ATI booth demoing the R520 demo.

Perhaps this is what they meant when "the final RSX should even be faster" (I don't remember the exact phrase right now).

Unless they squeezed in the new desktop G70 part in lieu of RSX, some don't make the distinction but they were able to demonstrate real time HDR in both the Ureal3 demo and the Luna one. Most dev kits i've read from the Sony front use twin 6800 Ultras, and RSX is supposed to be in excess of twice the power of that SLI rigup. So devils advocate.....if they were running the G70 to give a taste of what's to come.....which has less power than the definitive unit, I'd say that bodes well.

What!? RSX is supposed to be as fast as a couple of 6800 ultra

 

[SedentaryJourney]

You sure they claimed it was in excess of twice the power of an SLI rig? That's 4 6800 ultras.

 

[Mordecaii]

I'm pretty sure the official quote was that it was supposed to be faster than 2 GeForce 6800 Ultra's in SLI... so they were saying it should be faster than the dev kits, but by how much we don't know.

That is absoluty correct. Faster than both, but we don't know how much faster. My question is when do you guys expect the devs to get the beta kits now that we have this news?

Jen-Hsun seemed to imply that it is as fast or faster than the twin 6800U's, one of the slides in the conference clearly implied that its more, it's the side that has the twin cards in the pc and the RSX side by side and stated clearly (whether a marketing FUD or not) that it was fully twice and then some. Maybe as much as 25-50% more but certainly not twice as fast as the older models in SLI config.

 

[mckmas8808]

Damn now Taciblue where can we find that slide? Please give us a link, website, or something. I believe you we just need to see it for ourselves.

Yeah..but you wrote something different Now it's crystal clear anyway..

 

[Tacitblue]

Took a frame out of the conference video, will image shack it shortly

I believe those were the same slide shown in Sony's pre-E3 conf.

[Tacitblue]

When you think of it, why wouldn't it be more than twice as fast, the bandwidth (35GB/sec) between Cell and RSX puts even PCI-Express x32 to shame. Same with X360's 22 GB/sec bandwidth between XCPU and Xenos. They're both faster than a single card implementation on a PC which is 16 GB/sec per card.......is that about right? SLI bandwidth is more than the dedicated bus on 360 but still fractionally slower than PS3's. And its clocked higher than G70.

As far as I know, only the terrain demo was Cell only, and even that used two Cells. I just watched the Press conference, and there is nothing that hints otherwise.

 

[Tacitblue]

Yeah, IBM's STI center in Austin used the twin Cell blade (I presume) for the Mt. St. Helens topo demo.
