M5 Ultra Mac Studio Targets 768GB RAM, but Supply May Cut That

Apple is testing an M5 Ultra Mac Studio with up to 768GB of unified memory, though chip shortages could force a more modest launch around October 2026.

Apple's next Mac Studio exists on paper — whether it ships as described is a different question.

Bloomberg reports Apple is preparing an M5 Ultra chip as the closing act of its M5 lineup before moving on to the M6 generation. The chip is expected to carry around 36 CPU cores and 80 GPU cores — a modest step up from the M3 Ultra's 32-core CPU and 80-core GPU. Apple has tested configurations with up to 768GB of unified memory, but memory supply constraints may prevent that option from reaching customers. A launch around October 2026 has been floated, though Apple's own delivery estimates for the current M3 Ultra already stretch into that window, which is not an encouraging sign.

The gap between what Apple tests and what it sells has become a recurring theme. The company already pulled higher-memory configurations from the M3 Ultra lineup in March, leaving buyers limited to a 96GB option — a strange ceiling for a machine aimed at professionals who need headroom. If the same supply pressure follows the M5 Ultra to launch, the headline number of 768GB becomes a press release figure rather than a real purchase option.

The Mac Studio hasn't been updated since March 2025, which means any buyer today is paying a premium for hardware that's already a generation behind — and Apple has reportedly raised prices across the Mac line on top of that.
