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.

Neuro The CPU is what makes the difference, sorry ps4
The systems not even out yet, for all we know, they could be lying, or Sony may have something even better.

You can't just rely on the CPU.

So, you're depending upon the CPU? Okay. Seems logic.

Dr-JPawnStars-Skillz The CPU is going to be way better hopefully
It's going to be good, that's for sure
Yeah it's a little better than ps4s but ps4 has the GPU
The graphics will be remotely the same for both consoles.
If they weren't it would take game developers a bit longer than normal to develop games.

Although this CPU doesn't stand a chance against any gaming computer, i'm still very excited to get my hands on this console and try it out on my own time.

Dr-PonyfilePawnStars Still going to be really smooth though
Yeah there won't be any major issues with the console running smoothly it will only take a small amount you won't even realize it has gone to be honest.
They better pray to whoever that the Xbone first gen has a much lower failure rate than 56%
