Well... more of a question leading to a discussion then a proper discussion but...

Geekbench seems to have become one of the most important cross plataform benchmarks on the market right now. and if we are to trust its results it would state that a Apple A11 is around 50% of the speed/power/number crunching capability of a Top level Core i3 from intel and can easly surpass an entry level Mobile i3

The geekbench results for a Apple A11 are 4K single core and 11K Multicore,

When it comes to i3, the Entry level I3 7100u that goes in to 400 buck economy laptops is around 3.5K single core and 6.8K Multicore while the top of the crop i3 processor like the 7350K doubles at 9K single core and 18K multicore.

Now you might say "well, Intel processors being Cisc x86 and the apple A11 is a Arm processor, Oranges and apples" but we have learned from the SBC market, largly impulsed by the Raspberry Pi that a Arm processor can go a long way with a Desktop compilation of ubuntu, Raspbian and other distributions that have been ported to Arm processors from Broadcom, Allwinner, Rockchip and Amlogic.

And people are forgetting that Mac OS X Is a Posix/Unix based OS from the BSD branch (Mach kernel) originally written for the IBM 68K successor G series which was then ported to intel X86. the question how hard would it be for apple to port it back to risc (ARM in particular),

Also when looking in to power consumption.

The i3 7100u has a 15Watt TDP and the 7350K has a 60 Watt TDP

Now Apple dosnt release TDP figures but an educated guess looking at battery consuption and benchmarks put it between 2 and 5 Watt TDP, Meaning that even in the worst case senario of 5 Watt TDP, the A11 is getting 50% more performance then a i3 7100u using a third of the power.

and while the i3 7350K doubles the performance of the A11, it consumes 12 times as much power.

Meaning that apple could use a 4 SoC cluster that would consume around 20 watt TDP (note, TDP is the maximum theoretical power consuption of the CPU in lab conditions, it will will not consume that much in day to day use) and could easly exceed the i3 7350K performance for 1/3 the power consumption.

TL;DR : am i getting the numbers wrong or are the days of Intel based Macs numbered ?
