Geekwire reports that Yusuf Mehdi (chief marketing officer) has confirmed that the Xbox One CPU has been improved from 1.6 GHz to 1.75 GHz.
Another Microsoft employee Albert Penello took to NeoGAF and added some interesting facts.
"As I'm sure you've figured out - you don't announce something like this at the same time you're working on it. Obviously this has been in the works, but now that we're in full production we felt OK about announcing it.
Devs should start seeing this soon - so any performance gains were happening on the 1.6 boxes. (everything at PAX was on the 1.6). This is a boost to developers on top of the optimizations going on."
Showing his frustration with the nature of the internet Penello then added:
"Lastly - can I PLEASE finally get you over this "we're having production issues" thing that's going around? We increased the GPU 6%. We increased the CPU almost 10%. We have been showing retail boxes. We are now in full production."
Now if you're that comfortable perhaps you'd care to actually, you know, announce a launch date?
