<observations> Date: June 25, 2026 * 🔴 (12:36) User stated primary laptop priorities are: (1) less heat/thermals, (2) battery efficiency — speed is secondary ("hopefully faster but more importantly") * 🟡 (12:36) Assistant re-ranked Framework mainboard options based on heat/battery priority (replacing prior performance-first ranking): - Ryzen AI 7 350 (£599): **lead recommendation** — 8C/16T Zen5 on N4P, better perf/watt than user's current N4 7840U, cooler under load, no multi-thread regression, mature AMD Linux support - Ryzen AI 5 340 (£399): **max battery/min heat pick** — coolest/most efficient AMD option, 6C Zen5c, lowest TDP, cheapest; trade-off is slight multi-thread downgrade vs current 8-core 7840U - Panther Lake (Intel Core Ultra Series 3): **risky/wait** — Intel 18A node is genuine efficiency play, but pre-order, unpriced, Linux power management immature at launch; advised waiting for reviews + Linux power-management reports before committing - Ryzen AI 9 HX 370 (£849): **skip** — most heat, highest power draw, most expensive; worst fit for stated priorities (prior "recommended" status reversed) * 🟡 (12:36) Assistant caveat: Zen 4/N4 → Zen 5/N4P is incremental efficiency gain (~10–25% better light-use battery, noticeably cooler/quieter under load), NOT a step-change transformation; board swap does not change chassis, display, or battery capacity * 🟡 (12:36) Assistant noted only Lunar Lake / Panther Lake-class Intel silicon offers a genuine step-change in battery/thermals; Framework did not adopt Lunar Lake due to soldered RAM and low core count
