Apple M1 Ultra 20 Core — Benchmarks & Specs

Short answer: the Apple M1 Ultra 20 Core generates 8.5 tokens/sec on llama3.1:70b (q4_K_M) under ollama in a single cited run, per kunalganglani.com LLM Benchmarks; there are too few comparable runs on file for a median.

Bottom line: how fast is the Apple M1 Ultra 20 Core?

For local LLM inference it generates 8.5 tokens/sec running llama3.1:70b at q4_K_M under ollama, per kunalganglani.com LLM Benchmarks. In PassMark CPU Mark it scores 41,380–41,392 points, across two PassMark results (PassMark CPU benchmark listing, PassMark CPU benchmark listing). Across all its cores it scores 24,210–24,216 points in Cinebench R23 multi, across two published results (Cult of Mac, mac studio with m1 uitra review).

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 M1 Ultra 20 Core is a processor from Apple. Data on this page draws on 11 synthetic benchmark results (top 10 shown), 13 community AI inference reports, 3 measured game frame-rate results, compiled from llama.cpp GitHub perf thread, Geekbench Browser, kunalganglani.com LLM Benchmarks, PassMark, Tom's Guide, AppleInsider, CpuTronic, Cult of Mac, Mac Expert Guide, MacGamingDB, Notebookcheck; each table row links to its source. Read this page when shopping the Apple M1 Ultra 20 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 M1 Ultra 20 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 M1 Ultra 20 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.
