You have no right calling on proof, who hand waves continuously and never gives proof. And yes for Geekbench graphics tests, Apples GPU renders using 16 bit integers and not 32 bit SP floating point like AMD, Nvidia, or Intel.

BTW there are AAA games that run on ARM. Civ6 is one that does run on Android which is ARM. However they don't run it anywhere near as fast graphics wise as a low end AMD64 laptop. Like my many year old Lenovo Idea 300 which is a A10-8700 with 6CUs at 800MHz and a single channel 8GB DDR3-1333. The Apple GPU performance article said the 2700U had 6CUs, but the 2300U is the one with 6CUs at 1100MHz and likely dual channel 2x4GB DDR4-2666. The 2700U has 10CUs at 1300MHz. The current one for comparison is the 4700U with 7CUs at 1600MHz in the same 12-27W cTDP envelope.
