The road leading up to the reveal of both the Xbox One and PlayStation 4 was a long one. With countless rumors, leaked specifications and assumptions about the hardware, many lines in the sand were drawn far before actual specifications were released.
Today we may finally have some confirmation of what we can expect from the Xbox One and, surprise-surprise, they are very similar to what we have expected all this time. 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.
