How 'bout a close-up of that Apple A5 chip? 1 GHz Dual-core processor with 512 MB of DDR2 RAM... Yowza.

How do we know it's 512 MB? Check out the marking, specifically E4E4, denoting two 2 Gb LPDDR2 die—for a total of 4 Gb—or 512 MB. Thanks, Anandtech!

Oh hey, what's this? According to Chipworks, our German iPhone (marked in red) has Samsung DDR2 RAM, while the Aussie iPhone 4S (yellow) contains Elpida DDR2 RAM!

If Siri has an address, this is it. Though iCloud integration can be used with any iOS 5 device, Siri only works with the dual-core-equipped iPhone 4S.

Come on out, Siri. We don't wanna hurt ya. We just wanna talk.

Chipworks was cool enough to provide us with a die photo of the A5 processor.
