    Can someone please explain how it contains 2 512Mbit SRAM dies, when the highest density SRAM available is 64 Mbit ?

    I don't even see the signatures, I've turned them off. If you are so worried about someone "shoving" their opinions down your throat, turn off signature display. Most forums are cleaner / better without sigs anyway.

    What baffles me is that the iPhone makes little to no use of System-on-chip ICs. You can bet that the next version will. What this means is that there will be more room for battery.



    On that note, I'm glad I don't have a gen 1 iPhone. gen 2 will be a SUBSTANTIAL imrpovement.

    They're SDRAM... not SRAM



    - the CPU could be similar to the S3C6400 (http://www.samsung.com/products/semi...00/S3C6400.htm)

    - since this is also based on the ARM1176JZF core

    - not too shabby

    - but I'm not sure how this relates to the S5L8900 on the die shot... the iPhone CPU seems to be a new or unknown media variant

    - the closest thing (namewise) being the S5L8700 - which is Arm9 based



    It would be interesting to find out if the S5L8900 has a 3D Core to help out with all the cover flow animiations.

    The CPU Chip is as a SOC ic, and it's packaged with 128Mbytes of SDRAM - so it's quite a dense solution.

    If you want to see a real SoC, look at the TI OMAPs. A stacked package of CPU and DRAM is not an SoC (it's a SiP), and it's hardly impressive. The point is that the gen 2 iPhone will be a substantial improvement. Not only will it probably support 3G, but it will undoubtedly do so with a much smaller board and a correspondingly larger battery.

    You're right, the TI OMAPs are SoCs - as is the iPhone CPU (S5L8900)

    - we don't know the exact specs of the S5L8900, but it seems to be a Arm11 CPU (ARM1176JZF), with a good assortment of peripherals (similar to the S3C6400)

    There's some speculation that it includes a PowerVR 3D Graphics core (MBX)

    - which will make for some interesting 3D game possibilities



    I'm just speculating here, but I'd say the iPhone CPU is somewhere between the OMAP2 generation and the OMAP3 generation - which is pretty good.



    Again, just speculating, my feeling is that this chip will be used for core processing for iPods & iPhones for the next couple of years.
