Microsoft's Xbox One engineers reveal more about console's CPU
The highly technical interview has lots of information for hardware junkies, including more on the Xbox One's custom APU, which Microsoft co-designed with AMD. The CPU has eight cores based on AMD's Jaguar design. When asked why Microsoft picked this configuration instead of four Piledriver-based cores, Baker stated:
The extra power and area associated with getting that additional IPC boost going from Jaguar to Piledriver... It's not the right decision to make for a console. Being able to hit the sweet spot of power/performance per area and make it a more parallel problem. That's what it's all about. How we're partitioning cores between the title and the operating system works out as well in that respect.
The Xbox One has 15 processors inside the system on a chip, according to Baker, "eight inside the audio block, four move engines, one video encode, one video decode and one video compositor/resizer." The audio block was designed completely by Microsoft and made to handle 512 simultaneous voices for audio in games. It can also handle the speech pre-processing for the Kinect add-on.

DavidDo0MDr-J I think the CPU is perfect.
That it is. So many trolls in comment sections everywhere, including IGN, TTG, x360a, TA, MajorNelson, USgamer, EUROgamer, Kotaku, io9 and many more, try to spread that old "50% more power" rumor, which has no roots to reality. All they are proving is that they have to knowledge of the inner workings of a processor. They clearly do not understand the technical differences between DDR5 and DDR3+eSRAM. Anyone with an actual understanding of the technology can clearly see that both the CPU and GPU in the Xbox One are works of art, perfectly balanced to achieve their goal.
It is nice to read these comments and see that I still have fellow free-thinking intellectuals in the gaming community. :]
Yeah I understood nothing you wrote(tech wise) but I must agree
