Apple's new M3 Ultra is making headlines for packing 512GB of memory, but how does it compare to the M4 Max? Find out in this detailed comparison.

This is the kind of computer that can’t be reviewed in a matter of days, so we’re just getting started.

The Apple Mac Studio Ultra, even at more than $14,000 is a bargain if you’re looking for as much system memory as possible, at $28 per GB. That’s a bit less than Puget Systems and almost a third of what you’d pay for a maxed-out Mac Mini (or half the Apple Mac Pro with its puny 192GB RAM).
