Assuming they used an interposer they could fit say 4* Stacks of 4 DDR4 chips and that would be the ideal configuration, but there could be a problem with yields for the whole chip as they won't be able to test the DDR4 chips until they are attached to the interposer right?

Yes, I think that's true.

I guess it depends how much it would cost to do these 4 stacks on interposer versus 16 chips on a PCB. Where's the tipping point when stacking/interposer becomes cheaper? I predict that high-end PC GPU's will go this way eventually as they'll need buses that are extremely wide.
 
Hey thanks for taking the time, it gives us a ball park of somewhere between say 70-100GB/s bandwidth for Durango.

I'm not sure about this, but I think stacking can only be used to increase capacity per area, not bandwidth, so 4x4 DDR4 would be only 128bit wide, so that'd be 50GB/s ?
If they are able to put memory on an interposer in a cost effective way, wideio2 makes much more sense. A similar 4 chip wide configuration would be 500GB/s at 1066MHz DDR. So the AMD picture shown earlier, with 2 memory stacks on an interposer, would be 250GB/s.

There are to be four versions of the dev kit, we were told. A previous version was essentially just a graphics card. The version shipping now is a “modified PC,” and the third version, appearing in January, will be close to final spec. A final version will be delivered to developers “next summer”.

Some US developers attended a “disclosure meeting” at Sony’s offices this week, with a further meeting to take place in the coming weeks. The purpose of the meeting is for Sony to tell studios what the machine is designed to do, to detail hardware and to show a set of presentations.

Our source told us that Sony is only calling the machine Orbis, and is not using the words “PlayStation 4″ in these meetings at all.

Orbis, we were told today, is based on the AMD’s A10 APU series. An APU (Accelerated Processing Unit) is a combined CPU and GPU.

PS4′s APU was described today as a “derivative” of existing A10 hardware. The hardware is “based on A10 system and base platform”.

The “ultimate goal” for the hardware, we were told, is for it to be able to run 1080p60 games in 3D with “no problem,” to create a machine that’s powerful enough for “today and tomorrow’s market”.

The dev kits have “either 8Gb or 16Gb of RAM. Deduce from that what you will.”

The hardware is not being made in Japan, it was said.

When asked if PS4 will have an optical drive, specifically Blu-ray, our source responded: “Of course it has.” We’ve been told the hard drive will be 256Gb “as standard,” but it’s not clear if it’ll be a normal HDD or a solid state drive.

We were told that Sony’s aim with Orbis is to avoid problems involved in launching PS3 by creating something “very affordable” but that “isn’t a slouch”.

The machine has WiFi and Ethernet connectivity and HDMI out. Our source said the was “no difference” between PlayStation 3 and Orbis input/output.

The UI, however, has been revamped. It was said today that players will now be able to press the PS button mid-game and travel “anywhere” on the system. An example given was buying DLC from the PS Store mid-game then seamlessly returning to play.

“They’re trying to make it as fluid as possible,” our source said.

We were also told that the machine will be designed to accept system and product updates in the background, and that it’ll “always be standby mode”. When you set the console up, we were told, you’ll be asked if you want to allow background downloads. You can, of course, disallow them.

No details have been given on the pad as yet. Confirmation is expected this month.

Orbis is expected to be announced at an event “just before E3″ next year.

Pretty nice leak. I'm inclined to believe its true based on the details given about OS. The thing that is interesting is 8-16GB quote and that can't be GDDR5 that they originally planed based on leakes.
 
A10 is an odd word choice since that's not an architectural label. Are they saying it's Trinity based?
1080p at 60 with 3D, no problem?
There's something missing, since I've seen many benchmarks where the APU can't sustain that load reliably and some where it falls very short.
Sure, we may be counting on fanciful to the metal optimizations, if that is possible for a desktop derivative, but the gap in performance in some scenarios is wide even for that.

Well i remember Sony said PS3 can do every game in native 1080p
Don't really care that until they officially announce the spec
 
The only thing we can deduce about the RAM is there's going to be at least 4GB in the final machine. :LOL:
OTOH A10? While the CPU part of the chip is decent, but the GPU part is really weak. Isnt there any additional discrete GPU coming the APU?
 
I thought I'd already posted this but I can't find it. :???:
GB or Gb?
Almost certainly GBytes. these are dev machines 1 or 2 GBs isn't going to get you very far. Large amounts of a RAM in a dev kit can prove essential depending on tools. eg. A couple of VMs allowing interaction between Orbis and a PSMobile device. As RAM is cheap, no reason not to put lots in with plenty of headroom for future development functionality. The 8 or 16 GB value is unlikely to be the amount of RAM in PS4.

1080p at 60 with 3D, no problem?
That's just marketing talk. We all know the current consoles can render stereoscopic 1080p60 games - you just need to make the right compromises. You can't target a rendering res or stereoscopy (unless there are hardware features to support 3D). You just put in as much GPU as your design allows and let the devs use it however they will, which will mean some amazing 2D, 30 fps rendering and some simpler 3D rendering.
 
The thing that worries me with in that leak is the a10 based kit development. That has to be accompanied by a discrete GPU? If so, the site would have told it though...
