Dream Machines, the first seller to list the chip, expected to ship by the end of March or early April 2025 (Club386, 4 February 2025). The Asus ROG Strix G16 reviews followed in June and July 2025. The exact first retail date was not found, so the month is approximate. Last checked 15 October 2026.
