PS3-tech?

Yep, sure looks like it! (Unless it's a completely meaningless PR announcement.)
Rambus said it will show plans to get bandwidth of 6.4GB/sec per Yellowstone RDRAM chip.
If Sony uses two Yellowstone RDRAM chips, the same number as in the PS2, that would give PS3 12.8 GB/sec of main RAM bandwidth. And if they use four RDRAM chips, they'd get 25.6 GB/sec of main RAM bandwidth.
So maybe they will have enough bandwidth to feed their 16 CPUs after all.
Interesting! I wonder how much latency Yellowstone RDRAM has.

If they could/were to use a YellowStone based solution @ 6.4Ghz instead of 3.2Ghz, they would yeild 25GB/sec with 2 chips and 50GB/sec with 4 - as shown at the following url, slide 9.

Whats interesting is that when I started looking at this a few months ago (and people here laughed at me), I found that even going back to late 1999 during a RDF conference - the 30GB/sec number for a next generation digital console keept popping up all over the place.
Um, the idea behind Cellular Computing is to embed many simple cores on a single die with on-die memory. Do a search for it at IBM and you'll see.
PS. Why did anyone even doubt that the Next Generation Playstation wouldn't use a Rambus based solution? Okomoto was just the Keynote speaker at RDF '02 Japan.

"First, when it summarizes simply, it becomes as follows. The Cell, DRAM memory of the processor core + suitable quantity plural, builds in network interface to that perhaps, becomes the tip/chip which has autonomous computing function. The on that in the Linux base, the open source community Globus (the Globus.org) it is presumed it is the conception which actualizes the distributed computing which is based on grid protocol." - Presentation by Okamoto Noboru, GDC 2002, Translation

Yes it is, and we know toshiba licensed the tech, so they could very well upgrade to a 32-64-128bit bus.... i'd expect the later, a couple of those and they could cause quite a shock/ruckus... with 300GB/sec...

That's a good find 
Vince, if CELL ends up in PS3 this main-RAM could be pushed mostly for the GS3 as the CELL chip would need external main RAM perhaps less than the GPU ( which needs to store all the textures, etc.. )...

What's with this obsession to make a narrow serial bus wide? A bus is good, not because of certain features alone, but because of the end results. The whole point of a high performance serial bus is to be narrow but very high clockrate. Making it (or wishing it to be) arbitrarily wide just because other buses are so shouldn't be the focus.

It would be nice to see a PS3 with at least 48-50GB/sec of main memory bandwith--as much, or slightly more than the graphics memory bandwidth of PS2. Or even 96-100 GB/sec using 8 chips @ 6.4 Ghz
Though the really insane numbers are most likely going to be on GS3

Will that Blue-ray disc drive be in there? Does it even matter if it is not, given the massive storage capability for games with just a conventional DVD-ROM?
randycat99 said:
If it wants to be backwards compatible with regulard DVDs then no as Blue-ray is not backwards compatible with regular DVDs. Anyway the DVD forum has already adopted the next generation DVD standard jointly proposed by NEC and Toshiba which is backwards compatible with all existing DVD standards.

Or they could just go the 'standard' route and have two seperate lasers or something...
Hell, that would go well with Sony's difficult-to-programme-but-great-returns-with-effort mentality. Imagine if you will a disc drive with multiple independant lasers, each of which can be controlled independantly for vastly improved data throughput and seek times.
Load times...? What are those?BenSkywalker

I hope that all the next gen consoles use Blue Ray. It was recently announced that DMC2 would be utilizing 2 DVDs, and that's for a system with 32MB system RAM and rather limited texturing capabilities. Given that all of the next gen systems should run 1080i as a native resolution I would hope that we will see significantly improved texturing over even the best titles of today, inclduing the use of 3D textures. Then there is my hope of HD DVD utilizing MPEG2 instead of MPEG4 which would require Blue Ray(less artifacts with MPEG2). I'm really hoping that Blue Ray makes it in to all the next gen consoles.
Edit- The DVD consortium already adopted MPEG4? Does anyone have a link?
