See part 1
I recently bought a lovely laptop, Asus Zenbook UM3402. It replaces a Dell Latitude 5521, partly due to bad battery life (about 2 hours), which is a pain since the country (South Africa) faces power outages as long as 4 hours.
To check performance, I used Rust JSON Benchmark:
git clone https://github.com/serde-rs/json-benchmark
cd json-benchmark
git checkout de23484ca078b9756e6e35f2a7a3fd1e806769bc
rustup override set 1.66
cargo build --release
cargo run --quiet --release --bin json-benchmark
Results for the Zenbook:

The Zenbook (Ryzen 7 5825U) is a bit slower than the Latitude, except for the SIMD tests. I expected the Latitude (i7-11850H) to be a lot faster, given how hungry it is for battery.
