They all make it seem like it is some kind of Intel's architecture for not being "efficient" enough. As a result of this I am convinced I live in the twilight zone. If Intel gets in its hands the nodes Apple has been working with, it will produce about the same efficiency and performance chips. This goes without saying. If incompetent Apple managed to do so, it will be a walk in the park for Intel.
A note on performance per watt. Some people just divide gigaflops per watt and make a conclusion about efficiency. But lack of common sense and basic education makes them reach at completely wrong conclusions. Letting aside that they disregard lithography altogether, they have also little understanding how performance per watt scales from low power to high power systems. So , they take, on same lithography[sometimes different ones which is hilarious] , 2 chips one at 5 watts and one at 150 watts. When they calculate the low power system they see for example it is 10 gigaflops per watt. So , they expect ,like the ignorant they are, the high power system to output 150 x10 =1500 gigaflops. When they see it produces "only" 150 gigaflops, they freak out:"yes it is more powerful but inefficient" ROFL. So if an 100 hp car does zero to 100 km/sec in 10 seconds, according to them, then a car with 1500hp it should do it in 0.6 secs . Really?
