If you’re counting by the framebuffer than the only 2x is the hidpi-forced-into-lowdown like the link suggest. The ratios I’m referring to is the UI scaling against the physical display pixel dimensions.
Apple basically settles into 220 dpi physical displays (250 moc MacBook Pro), rendering UI at a 2x scale as a default, except for MacBook Airs.
