We don't know, is the only good answer. We haven't done much trying in the past 10 years.
Intel's Lakefield was doing quite well in the tablet/MID space. It also had the disadvantage of comparatively ancient Atom-eaque cores- far worse than Intel's new E cores-and a massive massive huge Skylake core.
ARM is no longer behind by all that much on single threaded. On geekbench a m2 can do 1916 points, a 7950 2300points. Slightly bigger gap on Cinebench, 1580 Vs 2050. A big part of the gap here is almost certainly the Hz being so different.
We just don't know. There's old beliefs we have held but we had so little evidence for these biases then. X86 rarely tried to be really tiny, had so much more to learn if it was to succeed. ARM rarely tried to be big, and has been learning. There's scant evidence there are real limiting factors for either.
