Apple's M5 Ultra Puts 4.5x AI Compute and On-Device LLMs Within Reach

Apple's M5 Ultra, announced August 25, 2026, is its fastest consumer chip yet. Each of 80 GPU cores includes a Neural Accelerator, yielding 4.5x the AI compute of the M3 Ultra. With 512 GB of unified memory at 1.2 TB/s, large language models can run entirely on-device — something no discrete-GPU workstation matches at similar power levels.
