Selenium benchmark with settings of Benchmark: Speedometer 3.0, Browser: Firefox. Core Ultra 7 256V: balance_performance was the fastest.

The "balance_performance" is the default mode of operation for both of these ASUS Zenbook laptops on Ubuntu. With the Speedometer 3.0 benchmark there was a tiny advantage to using the "performance" profile on the Ryzen AI 9 365 laptop but unchanged for the Core Ultra 7 256V. When switching to the "power" profile there was a big drop to performance...

The Lunar Lake laptop went from around a 11 Watt power average in this web browser benchmark to just 3 Watts in the power profile. The Ryzen AI 9 365 dropped from a 9 Watt average down to 5 Watts. On a performance-per-Watt basis, the Core Ultra 7 256V with the power profile was the notable leader for efficiency.

Here's how the CPU peak frequency differs among the ACPI Platform Profile modes on each laptop.

Not only does the power profile lead to much lower CPU power consumption but in turn also leading to much lower CPU core temperatures.

It was a similar story with the Jetstream 2 browser benchmark running within Firefox that the Lunar Lake laptop with the power profile led to the best performance-per-Watt while sipping just 3 Watts on average compared to 5.4 Watts for the Strix Point laptop.
