Did anybody else notice that in the Architect Meeting, one of the Microsoft guys said that each CPU will execute six instructions per clock cycle per CPU Core? Sony’s paperwork shows one per CPU per cycle per core.
Is this a misunderstanding? How are they doing that? And if so, doesn’t it make the Xbox One’s CPU significantly more powerful?
Additional Info: "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)."

I don't know but each Jaguar core can perform 4 operation per cycle... that how the PS4 CPU works.

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.
