Apple’s M5 Ultra With an 80-Core GPU Will Power Through Your AI Models and 8K Video
Apple announced the M5 Ultra on 25 August 2026 alongside a new Mac Studio: an up-to-80-core GPU with a Neural Accelerator in every core, up to 512GB of unified memory at 1.2TB/s, a 32-core Neural Engine and a media engine rated for 33 simultaneous streams of 8K ProRes 422. This breakdown separates the peak-theoretical claims from the measured workload figures, works out what 512GB actually buys you when you run large models locally, checks the 8K video claim against a real timeline, lists the prices and ship dates, and sets out the questions Apple did not answer.
