Well sorry for not being clear to begin with. In the aforementioned thread there were several comments about how either xenon or ppu are not exactly poster child for "high" performance in order cores. I found what ARM does to this new CPU interesting as they managed (supposedly) to improved its performances compares to their previous IO cores while lowering power consumption (a bit related to the lithography used though) and using less transistors. ARM stated that they optimized the CPU for android usage. A7 looks like a A8 done right. I believe that IBM power A2 is xenon heir, I expect it to perform closer to peak perf than xenon. To me a AT module looks like a Xenon done right.Can you give more detail on what parallels you see?
I find both those CPU interesting as designers seems to have significantly up the performance without relying on out of order execution.
About R&D cost of implementing an OoO engine and the following testing I believe there was multiple comments on the matter.Can you point to the statements that indicated this?
For the PPU and Px as well as the idea of SPUs I believe it's ERP that heard confusing noise /rumors on the matter (no matter the official statements).
Overall what I was trying to say is that neither Ms or Sony may found IBM with enough money so they "out do themselves". I don't expect IBM to do a better front end than what they did for the POWER7 for most likely a "lesser" project, neither I expect them to push out better "throughput optimized cores" than the power a2 for lesser project. IBM may jump on the opportunity to have MS/Sony so they found prject they had hanging around before hand but my idea was that MS or Sony may as well go with of the shelves parts save R&D and focus their R1D on putting everything together properly, or actually asking your opinion about such a choice.
