This point still stands even after geekbench 4 release, I won't confide too much on it for cross architecture and os comparisons.
I mean it might represent a fair comparison between the same class of processors over generations, but assuming it's close to SPEC as some are saying when it gives such different results is definitely a mistake:

Look at the spec_int results in that page and compare core-m, Broadwell 5-Y31 and Skylake 6-Y30 to A9X. To summarize, if you assume they are running at similar clockspeeds (~2GHz) during the tests half the benches were A9X leads it's 10-20% (only one is a 38% advantage and over Broadwell) but the other half it loses badly, scoring like half or even less.
I quickly put the data in Excel and got Skylake 13% faster than Broadwell, while both have an advantage of 71 and 44% over A9X respectively. The higher end core-M is twice as fast but it's also running at a much higher speed, anyway it should give you an idea of what SPEC says while geekbench puts A9 IPC at higher than Skylake...
