There was a flurry of news articles a couple of days ago reporting that the A11 was on par with the most powerful dual-core Intel chips Apple is currently using: https://www.macrumors.com/2017/09/13/a11-bionic-chip-geekben...



geekbench is the only thing showing these outsized results, id be very suspicious of geekbench


What other cross-platform benchmark do you suggest? People are comparing it in Geekbench because it is the only big benchmark that is available on both platforms.


SPEC CPU 2017 or 2006

Here is an article that uses it:

snythetic benchmarks are notorious for being unrelistic and unreliable.

just because there isnt an alternative dosent mean that geekbench is accurate, id be pretty skeptical of claims that arm chips with a fraction of the transistors and power budget are somehow magically just as fast as big full fat x86 chips.


Power delivery, sure, but you’re off on transistor count. Wikipedia list a ‘Dual-core + GPU Iris Core i7 Broadwell-U’ as 1.9B transistors [1], and the A11 is 4.3B.

Should be noted the A11 is 6cores+gpu and the i7u is 2 cores + GPU.

And we are talking about per core preformance.


Current x86 chips are spending huge amounts of their transistor and power budget on tiny increases in instructions per clock.

When you have twice as many cores to play with then you can have better total performance with a lot less resource cost.
