Within the 2021 M1-series MacBook Pro lineup, the M1 Max was the option for 64GB of unified memory. That machine weighed 2.2 kg and came with three Thunderbolt 4 ports, an HDMI port officially supporting 4K 60Hz output, an SDXC card slot, and MagSafe 3 charging. By 2026, the 64GB threshold has been crossed by the M5 Pro. Apple's current specifications show that the 14-inch M5 Pro with the 20-core GPU can be configured with 64GB of unified memory. The machine weighs 1.60 kg, roughly 600 grams lighter than the 2021 16-inch model, but the screen also shrinks from 16.2 inches to 14.2 inches. This is a difference between two distinct size classes, not a generational weight reduction within the same size. On the port side, the M5 Pro features three Thunderbolt 5 ports and an HDMI port. The display is a 14.2-inch Liquid Retina XDR panel with ProMotion up to 120Hz adaptive refresh.
If the main reason for considering an M1 Max was the 64GB memory ceiling, the M5 Pro now offers a direct alternative. The M1 Max has shifted from being the only large-memory option to being a large-memory used option. Whether it is worth buying depends entirely on price and condition.
Without current used market pricing data, a specific discount percentage cannot be quoted, but the evaluation method is clear: place the actual out-of-pocket cost of a used M1 Max 64GB next to that of a new M5 Pro 20-core GPU 64GB, and factor in the remaining warranty.
