If an ARM/phone cpu is to run a x86 Emulator then I think the FULL potential of the combined CPU's are going to be required. Or as many as the device/CPU will allow. Simple Logic, do you think it would run better on 1 Core so to speak?
I think the demand on the CPU will be high not low.
And herein lies your fallacy. You appear to just outright ignore examples of devices like the iPhone that prove this is not just a matter of core count. You also ignore mentions of the software related reasons that explain why your stance is wrong (like the relationship between software threads and cores). I can only guess you're glossing over it because you don't understand it. Because I'm getting no responses from you on those issues, I can't say what information you're missing or what it is exactly that you don't understand.
Companies who sell their hardware by appealing to the non-technically educated geeks, will strive to improve whatever gives them an edge. They will happily build 8 core CPUs and throttle half of those cores down to the point of irrelevancy (although usually unnecessary as more than four rarely kick in anyway). As long as it gives them the more marketable spec sheet all is fine. In contrast, companies that don't market their devices based on specs, like Apple, are free to pursue more useful paths to improvement. Even Apple's newest chips are basically 2 core designs (2+2), as they aim to build the chips with the best single-core performance on the market. Technically, that is the far superior approach, at least for mobile devices!
Apparently you've never asked yourself why the core count for desktop PC's hasn't really gone beyond 4, despite that for smartphones we're regularly discussing 8 core or even 16 core devices, all of which are clearly inferior to any years old Intel i5 with 4 cores. This too should make it glaringly obvious that performance is not just a matter of core count. If things were that simple, even low end desktop CPU designs would be 32 or 64 core designs by now, as desktop chips aren't limited by the thermal or power usage constraints of their mobile brethren. Yet they rarely go beyond 4 cores. Unfortunately, you're apparently too stuck in the marketing bubble to question that.
To be 100% sure what the best solution would be for an x86 emulator on ARM, we'd have to understand the software design of the emulator. We don't, so there are no guarantees. However, based on the fact that very little of the x86 software we might reasonably run on on an ARM smartphone will employ more than two cores, I think it's far more likely that a design which emphasizes single-core performance (like Apple's
dual core A9), would result in far better performance than the designs which emphasize marketability and multi-core performance, like the 8 core designs you prefer. You're "simple logic" just isn't sophisticated enough. Yes, the number 8 is bigger than the number 2. That realization, by itself, just won't tell you anything about performance.
My goal is to educate people on technology, but I can't do it all on my own. I can get people to question what they believe. I can maybe get people to consider that the relationship between cores and performance is neither proportional nor liner and that the software side of the equation might be more important than the trivialities of hardware specs, but the actual work people have to do themselves.
I'll leave it at that.
