AMD Ryzen 7 7840U
Phoenix at ultrabook power: the same eight Zen 4 cores and Radeon 780M as the HS chips, tuned for 15-30W. Until Strix and Lunar Lake arrived, this was the x86 performance-per-watt benchmark — and Framework's favorite.
Pros
- HS-class core count at ultrabook power
- Class-leading x86 efficiency in 2023
- Radeon 780M enables real 1080p gaming
- Strong sustained performance from 15 to 30W
Cons
- Boost clocks dip at the 15W floor
- Single-core behind Zen 5 and Lunar Lake successors
- NPU too slow for Copilot+
