Next up are some battery power consumption numbers and looking at the CPU peak frequency (on any of the cores at that given point in time) look for a sub-set of the laptops while more detailed data coming in future articles. All monitoring via the Phoronix Test Suite was done on a one second interval. The Dell XPS and Lenovo IdeaPad laptops were running Ubuntu 20.04 LTS and maximum screen brightness during this round of battery tests.

The Ryzen 7 4700U during demanding multi-threaded workloads like compiling the Linux kernel was successfully clocking higher than the Core i7 8500U and i7 1065G7.

The Lenovo IdeaPad was consuming up to ~55 Watts during compiling of the Linux kernel while having full screen brightness but averaged out to 30.4 Watts.

During multi-threaded benchmarks like Coremark, the Ryzen 7 4700U was hitting up to 4.0GHz.

RawTherapee is another real-world application example showing the Ryzen 7 4700U clocking much better than the two Intel Dell XPS laptops tested.

The power consumption of the Lenovo IdeaPad was higher, but on a performance-per-Watt basis throughout different tests we found it generally even ahead of the Ice Lake laptop:

On a performance-per-Watt basis, the Ryzen 7 4700U / Lenovo IdeaPad was ahead of the two Dell XPS laptops, including the Ice Lake model. More power and performance-per-Watt data coming in future articles.
