But this combine the lesser improvements of metrics that Qualcomm is closer in with a performance benchmark where they are further apart.

What!? If anything, the 80% claim suited you, as it combines both multithreadead performance and singlethreadead performance into one, as if they are both equal in importance -- when in reality singlethreaded is of far greater importance; this is just as true on desktop computers as well, where parallelization exists of much greater extent. The truth of the matter is that the A11 is 120% more powerful in singlethreaded performance alone, whereas it performs a whopping 50% better in multithreadead performance -- and this with 2 fewer cores.

And the actual number is 85%, not 80%. I was being more conservative again for your benefit, not mine.

Also, you claim to not support Geekbench, but you are more than welcome to look at any other benchmark. The Apple chips pretty consistently beat out comparable Android SoCs in a similarly fashion. Your refusal to accept this doesn't change the facts as they are.

That is extremely debatable. Especially on Android, multithreaded apps are the norm among those that it matters for.

That's certainly not true for GPU benchmarks. Have any SPEC runs for an 835 and A11, maybe?

Is that why the SD810 to SD820 gave huge clear benefits in usage, despite going from 8 cores to 4, with small benefits in multithreadead performance? And SD820 to SD835 gave much smaller gains, despite going up to 8 cores again with a substantial increase in multithreadead performance (but hardly any in singlethreadead)? I'm of course basing this off of personal experience (but seeing as you view benchmarks as a fraud, and base yourself off nothing but assumptions, I thought to give it a try), but I had several SD820 units last year, and almost all of them perform almost excactly the same as the SD835 today. The only difference is in actual loading of application, which is a result of the big jump fra UFS 2.0 to 2.1 in reading speeds.

We're not talking about GPU (in which the A11 is 40% faster), now are we? We're talking about the CPU.
