That shared computing resources 312 could b the leaked diagram from vgleaks... there could yet be another bigger component that sits underneath and has 2gpu 2 cpu

Are you the new Jeff Rigbey?
 
I don't think we can go there by patents, they are a dime a dozen.

It would make sense though to try and understand what MS wants from this system, by taking a look at who's designing it.
 
Windows 8 doesn't use more memory than Windows 7 I think.



Noted. It's like graphics, diminished returns and all. We should probably stick with the Wii U, because going bigger doesn't seem to affect anything ;)

You are so stuck in defensive mode that you won't even take the time to process information anymore. It's time to step back and count to ten you are not being constructive or responding to reason anymore.
 
Is Oban = Kryptos or part of Kryptos? Is Oban the Transposer and Kryptos = Transposer (32nm SOI) + Jaguar and 8000 series GPU @ 28nm or is Oban and everything on it @ 32nm based on the Richland APU with piledriver cores and 8000 series GPU.

Richland or A10 just had info released on it. It's what many are expecting the PS4 to based on. If Charlie's Oban is 32nm SOI it's likely Richland based also.

At 32nm it's likely SOI which works but we have multiple rumors that Kryptos (Xbox3) and Thebe (PS4) have Jaguar Mobile CPUs.

At the top end is the quad-core A10-6800K, which features a built in Radeon HD 8670D mobile GPU, and has a TDP of 100W. This is a 'K' part, which means that it will come with unlocked CPU multipliers and GPU stream to unlock extreme overclocking.

"Richland" APUs are based on an updated Trinity architecture, and are built using the same 32-nanometer process and Piledriver CPU architecture. However, they differ from Trinity parts by having higher clock speeds, featuring updated Radeon HD 8000 series GPUs, and faster DDR3-2133MHz dual-channel memory controllers.

Problem with SOI is AMD is going bulk with 28nm and smaller die. Sweetvar26 said that both Sony and Microsoft switched to Jaguar for the 10 year life of the console and Jaguar is a mobile CPU that has a life going forward while SOI and Piledriver CPUs do not. The first refresh if not using Jaguar and bulk @ 28nm would require a very large redesign. If using Jaguar and bulk, the first refresh would likely be after 14nm and 3D packaging came on-line so no transposer would be required but 3D packaging has problems with heat so Piledriver/Bulldozer/Excavator/PPU/SPU type processors may have problems which also likely means no BC after 2-3 years. This is the problem with Oban as the entire SoC and all taped out Dec 2011 on 32nm SOI. It's also the problem with the A10 as the base for the PS4 or Xbox 3.

Oban as the transposer can be taped out @32nm on SOI and SOI saves a couple of steps (cheaper) in manufacturing eDRAM on chip. Oban at 32nm using SOI makes sense as an active transposer with eDRAM. eDRAM should be under Logic for heat dissipation reasons so transposer real estate is not wasted.

Again 2 PPUs could be on Oban @ 32nm SOI but other AMD packages 2.5D stacked on the Oban transposer using bulk at 28nm and even 22nm. This would work for Sony PS3 BC also, two PPU3SPU packages @ 32nm part of Oban or whatever Sony calls their transposer (Oban is a Japanese large blank gold coin with bumps).

Anyway with the above A10 information we know a A10 top end with 4 piledriver cores (2 packages) on SOI @ 32nm with a 8670 GPU is 100 watts. Take away the Piledriver TDP and give most of it to a 8000 GPU (Jaguar uses less power) (32nm SOI is apx equal to 28nm Bulk) add 20+ watts and the efficiency for the eDRAM and we might be coming near PS4 or Xbox 3 specs..
