About MacDiff

MacDiff (Mac Performance Atlas) at macdiff.com is an independent reference for comparing Apple silicon Mac configurations with normalized CPU and GPU indices. The baseline is the entry-level MacBook Air M1 = 100 / 100.

What MacDiff is not (ECCV, Ruby gem)

Searching for “macdiff” may surface:

An ECCV / academic computer-vision paper named MacDiff — unrelated to this website.
A Ruby macdiff gem / CLI — unrelated to this website.
Unrelated “Atlas” system monitors or X-ray products — also not this site.

This site is MacDiff — Mac Performance Atlas for Apple silicon Macs only.
