Initial AMD Ryzen 7 4700U Linux Performance Is Very Good

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.
