Xbox One Xbox One performance details have been revealed at Hot Chips conference

So what can we take from this? First of all, that the console is way more complex than anybody could expect, and that nobody can at this point predict its raw-performance or compare it with the PS4.

Some new things we now know is that there will be an 8GB flash memory. This could potentially be used to manage the suspended game states for quick switching. Another plausible theory is that the OS side of the console could be dumped into this memory, freeing up resources for better game performance. We also know that it'll have 1.31 TFLOPS of power. Also, it appears that the XB1 could have some kind of version of hUMA, which means that there could be uniformed memory access (maybe just in the one way).

During the Hot Chips conference the performance of the Xbox One has been revealed:

8GB Flash memory
15 special purpose processors
4 Command processors (2 compute, 2 graphics)
SHAPE offloads >1 CPU core
Memory coherency between CPU cores and GPU
Audio offload processor custom designed by Microsoft - 1 CPU core worth of processing.
68 GB/sec peak bandwidth to off-chip 8GB DDR3 memory.
204 GB/s peak bandwidth to 32MB of on-die storage.
The most important thing to note here is that the Xbox One supports shared coherent memory between 8 AMD Jaguar cores and it's DX 11.1+ GPU. This type of memory allocation could is very similar to hUMA - an architecture that was said to give the PlayStation 4 a massive advantage as per AMD.

Pretty cool, even though HALF that stuff is like...greek to me lol. But im sure its good news!

This.
It may look impressive, but even the latest PC manages to reach those numbers with no problem, so, the real question is, how will they use all of this hardware and what exclusives are going to take advantage of it?

This is where the devlopers will come in.
