Checked against the manufacturer’s official page on 2026-11-15. Fields missing from the page are left empty (unknown). Intel lists the release quarter: Q1'25. Memory speed: DDR5-6400 / LPDDR5/x-8400. Of the 10 efficient cores, 2 are low power (Low Power Efficient-cores). Intel lists 28 W base power, 20 W minimum assured power and up to 115 W in turbo. The laptop maker sets the power in each laptop, so benchmark results depend on the laptop model.
