Apple's A20 Pro runs 27B parameter model at double the speed of iPhone 17 Pro's A19 Pro

In the iPhone 18 Pro, the A20 Pro chip with two 16-core Neural Engines runs the 27B Bonsai model twice as fast as the iPhone 17 Pro on A19 Pro. Memory is 12 GB LPDDR5X with 115.2 GB/s bandwidth, but 2-bit models like Bonsai 2 do not fit.
