The iPad Air 11 Inch M4 wins on performance with a 2.3-point Geekbench 6 single-core lead over the M2 (per Geekbench) and better longevity projections. Both share the same 11-inch Liquid Retina panel, 8GB RAM, and 6.1mm chassis (per Apple's specs). The M2 remains a strong value pick for users not needing peak CPU speed.
