XBOX 360: Inside & Out (NO CPU die photo!)

It'll be interesting to finally see the die-size information when that gets released as well, almost a little dissapointed that they gave transistor counts but no die size. Still, better to have something than nothing!
 
That die looks very bizarre IMO. What's been said before was the thing was supposed to have a unified 1MB L2, but there's no trace of any large SRAM array on that photo. Instead there's a bunch of SRAM-looking blocks spread out across what might be all three execution cores, but those are probably L1 data and instruction caches. So where is L2? Cropped out of the picture?

Then, if the three blocks on the right are the three CPU cores, what are the two roughly square, vertically mirrored blocks on the left? As far as I can tell they look identical. Very curious.
 
The die photo is interesting...
There are clearly three very similar blocks on the right side, which are likely to be the cores. However, on the left side, there are two almost identical parts mirrored, and they look too complex to be cache. Does anyone have any idea what they are?
 
Well it's definitely bizzarre. I mean, is it possible something has been kept out of the CPU specs for secrecy reasons? Those two mirrored parts clearly have communication logic between them also.
 
Well I hope we get the die size soon, as well as a shot with the lvl 2 cache - it'd be interesting comparing the size of one of those PPC cores to the PE in the Cell.
 
Crazyace beat me to it.

This pics look like a Power5:

this is 2 core not 3
third will be a PPU ? :)

Given there is not a single piece of evidence that points to a 2-core design and absolute mass of evidence that points to a 3-core design what, pray tell, makes you say it's 2 core?
 
IGN mentions that the GPU uses 150m transistors. Doesn't that seem a bit low? The NV40 was 222m (on a less advanced process). Or do they count memory with PC graphics cards?

ATI chips have had lower transistor counts whan NVIDIAs for quite a while, comparing each generation. The NV30 had a lot more transistors than the R300 but look what happened ;)

You think the number is inaccurate?

Do PC GPU transistor counts include memory? To compare to ATi cards, the X850 PE comes in at 160m transistors.
