Hmm, do you have a link for that?  I was surprised when the original stuff said one per CPU per cycle.  Even the go ol' Xbox 360 does two per CPU per cycle.  And that's really going back to essentialy 2004 tech.

That would still give the Xbox One a 2 execution per CPU per cycle advantage, more or less depending on the Hz it runs.  So kind of negating the GPU differences, or tilting power in the X1’s advantage.

Sigh, I should just make popcorn and watch the fans fight it out.

Rumors have always maintained one per cycle which is why I've had that in OP for awhile now. Then Sony themselves confirmed it.

I'm thinking this MS guy made a mistake or wasn't referring to same thing we're talking about.

I'm waiting for more clarification on that as well as the nm sizing before I change the OP.

Yes, superchuck I was referring to your excellent thread and charts!

But ethomaz has shown, it looks like the PS4 can do two executions per CPU per cycle. (Actually 4 per 2 cycles provided the bandwidth is available.)

And Microsoft articulated again that they are pulling 6 executions per CPU per cycle.  That is a 66% advantage over the PS4.  Gosh, I makes me even more sad they didn't put a 2.5 Tflops GPU in the system.

"Some performance numbers were given for the CPU and GPU themselves but these cast more shadow than they do light. Microsoft claimed that each CPU core can perform six operations per cycle. The CPU is believed to be using AMD's Jaguar core, but typically this would only be described as able to handle four operations per cycle; two each of integer and floating point (though even here counting operations is complicated; the floating point operations could use vector instructions such as SSE2, in which case one operation would result in four actual computations, potentially giving eight per cycle for floating point alone)."

Read it here, they aren't even sure how Microsoft is accomplishing it:  http://arstechnica.com/gaming/2013/05/microsoft-talks-about-xbox-ones-internals-while-disclosing-nothing/
