they said thay want slow ram?

What did they say exactly?

Probably because they like to load entire levels into RAM
Kidding, don't know if they know how to stream yet.
They said that for that level of scene quality, they would like 8GB of RAM. The actual demo used 1.8GB of textures squeezed into the GPU's 2GB memory, and they had some trouble to get it down to that size, and that 8GB of unified memory would be a big help, something like that.
It's too hard work to google it thanks to all the thousands of repeater-sites these days, so hopefully you've got enough to go on to find out the real deal, as this is all I can remember.

SE should read sebbi's thread here on optimizing memory bandwidth and size
I wonder if anyone ever got around to translating the entire article though. I think only bits and pieces did.
Can't wait to see what 3-4GB of pure visual assets looks like though. Should be insane.

Very much this!
Just keep in mind that todays games run with 512MB and ~25GB/s. Now imagine what games can achieve with 3.5 GB @ 192GB/s, respectively 8GB @ 68 GB/s + 32MB SRAM.
I can't wait to see how the new Gran Turismo looks ...this is going to be sick!
It might be worth to mention that the assets weren't optimized at all - for example the girl wearing boots had her toes modeled and textured as well. So maybe giving them 8GBs isn't the only possible approach

Yes, this is totally fair of course. Then again, perhaps if you want your characters to be able to change their clothes, you'd need to have some of this modeled, just not maybe always rendered. I'm sure there are smart solutions here, but I also think that there is room for asset cost reduction by not having to do this so much in the next gen.
But I'm sure we'll see all sorts of interesting stuff happening next-gen. Really looking forward to it, to be honest!
I think just having a lot more bandwidth is certainly not enough. Say that we have the same memory as this gen but with much more bandwidth, then for many types of games the actual assets aren't going to improve, just the effects you can process with them. Here, secondary memory (HDD, SSD, BluRay speed, etc.) is going to matter a lot. The more internal memory you have, the less the secondary memory is going to be an issue, because you can stream a lot of stuff into memory. And the reverse is also true - the faster something like SSD, the less RAM you need (comparatively).
Question for you if you can answer. In a typical PC GPU, how much of the traffic to the memory is writing by the GPU?
For example, if you can fit the entire frame buffer in the embedded RAM, is there anything you need to write back to the GPU memory? If not, I would imagine then the memory can almost be treated like read only buffer for streaming assets. I would imagine that would make the memory accesses a lot more efficient as well. I would also imagine that I'm completely wrong on this.
There are intermediate buffers for various effects or rendering methods, and streamout is possible from various places in the pipeline.
The atmosphere around next gen launch is worse than last time. Durango looks like it won't be even in the same class judging by some people opinion (some knowledge people that is) and I'm kinda leaning towards that side too.
I probably wouldn't if it had processing power to match, as I believe MS engineers would thought about system not getting bottlenecked so obviously. But, since compute performances are seriously lagging, I guess we are going to see one console getting beaten badly in that area and that won't be PS4.

He speaks about "Durango refresh" as of console that would replace lackluster performing box that Durango could likely end up being.
If one of these vendors doesn't step up his game , Digital Foundry will be put out of business ...
Weeks ago it was like Durango > Orbis, and now it is like Orbis >>>> Durango... lol
