Maybe they're using the same supplier then? The timing seems quite convenient and it would make sense for MS to use 2133MHz DDR3.

I'm sure Microsoft will use more than one manufacture for memory... Micron, Hynix and Samsung.

Thanks for the info. Not one of AMDs memory partners so looks like my theory was completely off, lol.

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!

so how many transistors does the ps4 have or is that unknown

~3 billion.

PS4 didn't have eSRAM, Move engines, etc.

- 8-core Jaguar CPU ~500 million transistors
- GCN GPU ~2.5 billion transistors
- 256-bit memory interface ? million transistors

The PS4's APU is less complex, small and cheaper than Xbone's APU... that was because you read MS was having issues with the tape out and Sony not.

If that would be the case, there's one big/huge 1-up for Sony.
