Apple M3 Ultra 28 Core — Benchmarks & Specs

Short answer: the Apple M3 Ultra 28 Core generates 18.1 tokens/sec on deepseek-r1:671b (q4_0) under mlx in a single cited run, per Hostbor; there are too few comparable runs on file for a median.

Bottom line: how fast is the Apple M3 Ultra 28 Core?

For local LLM inference it generates 18.1 tokens/sec running deepseek-r1:671b at q4_0 under mlx, per Hostbor. In PassMark CPU Mark it scores 69,044 points, per PassMark Software.

Every figure above is a row in the tables below, and each row links out to the review or public benchmark database the number was taken from. SpecPicks aggregates published measurements; it does not report first-party benchmark runs.

The Apple M3 Ultra 28 Core is a processor from Apple. Data on this page draws on 23 synthetic benchmark results (top 10 shown), 16 community AI inference reports (top 12 shown), 9 measured game frame-rate results, compiled from MacRumors Forums, ComputerBase, Hostbor, llama.cpp GitHub Discussions, TBreak, Olares Blog, PassMark Software, CpuTronic, Digital Trends, EveryMac, Geekbench Browser, TurboVS, XDA Developers; each table row links to its source. Read this page when shopping the Apple M3 Ultra 28 Core, comparing it against other processors in your build, or sizing it for a specific workload (gaming at 1080p/1440p/4K, synthetic benchmark scores, or local LLM inference).

Gaming Performance (measured FPS)

Average and 1% low frame rates by game, resolution, and quality preset. Bars are scaled against the fastest result on this page.

Measured gaming frame rates for the Apple M3 Ultra 28 Core by game, resolution, and quality preset. “1% low” is the frame-time floor that determines perceived smoothness. A CPU’s frame rate depends on the graphics card it was tested with, named in the Test GPU column when the source records it. Each row links to its original review or benchmark database.

AI Inference Performance

Tokens per second under each model + quantization. Higher = faster generation. Bars compare runs across the same model.

Local LLM inference throughput on the Apple M3 Ultra 28 Core, in generated tokens per second for a single request (one user's generation speed). Higher is better; each row links to the community report or benchmark database it came from.
