More transistors doesn't necessarily mean better. Also those Xeon parts are like 150W compared to 10W for Apple's.Apple's A12 chip has 6.9B transistors for 6 cores on an 83 mm^2 chip. Intel's Xeon has 7.2B transistors for 22 cores on a 456mm^2 chip. That's 5.5x as dense, and the transistor count per-core is 3.5x higher for the Apple (ARM) cpu than the Xeon. So why do you consider Intel the more complex of the two?
