The 512GB M5 Ultra will ship in October with a massive 1.2TB/s memory bandwidth. 50% more memory bandwidth than M3 Ultra, 4.4x more than DGX Spark and M4 Pro. Stacking 4 x M5 Ultra, I expect you'll be able to run Kimi K3 / GLM 5.3 faster than the API (>100 tok/sec).

Why it worked

Leads with a specific number, which is concrete enough to be worth a second of attention.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Follows a clear Hook → Context → Landing shape, so the reader always knows where they are.
Written from experience rather than as advice, which is harder to argue with.
Short enough to read in full without expanding, which removes a step before the point lands.
Short sentences keep the pace up, so the reader never has to re-read a line.

The mechanics

Hook: Leads with a number
Structure: Hook → Context → Landing
Style: Conversational paragraphs at a steady pace.
Tone: personal, concrete, punchy
Mechanisms: Specificity
Written for: Engineers and technical teams
