Time to take a gander at this octopus lobo and see what makes it the leader of the pack. Highlights include:

Intel Core i7-6700HQ 2.6 GHz (up to 3.5 GHz) quad-core processor

Micron MT52L1G32D4PG-093 4 GB LPDDR3 (four chips for 16 GB total)

AMD Radeon Pro 450 GPU

Elpida (Micron) EDW4032BABG-70-F 512 MB GDDR5 RAM (four chips for 2 GB total)

Intel JHL6540 Thunderbolt 3 controller (one for each set of USB-C ports)

Intel SR2NH (likely a platform controller hub)

Texas Instruments CD3215C00 (labeled as Apple's T1 chip in their keynote; however, that does not appear to be true)
