Ah, you found it, too :) It was hard to read but I found it, of course. I am happy that MS allowed such a shot of their motherboard! I am still wondering about the APU... This chip is *massive*. It seems to contain the APU, the ESRAM and also the move-engines as no other chips are around that... Perhaps that's why it's 5 billion transistors.

5 billion transistor is big in any process.. In my guesses I see the Xbone's chip like:

- 8-core Jaguar CPU ~500 million transistors
- GCN GPU ~1.8 billion transistors
- 256-bit memory interface
- 32MB of 6T-SRAM ~1.6 billion transistors
- Data move and others fixeds units

Well that give us  ~1 billion transistors for the memory interface, data moves and others fixed funtions.

I think we will have to wait for the first teardowns of the usual websites. But no matter what, a hell of a chip. I hope to see more details from the "SHAPE"-chip aswell!
