This is a series looking at the BOSGAME M4 Plus Mini PC running Linux. In this series, I examine every aspect of this Mini PC in detail from a Linux perspective.
The BOSGAME M4 Plus Mini PC is a powerful computer based on an AMD Ryzen 9 7940HS processor with integrated Radeon 780M graphics.
The AMD Ryzen 9 7940HS is a mobile processor with 8 cores, launched in January 2023. It’s part of the Ryzen 9 lineup, using the Zen 4 (Phoenix) architecture with Socket FP8. The core count is effectively doubled courtesy of AMD Simultaneous Multithreading (SMT), with the CPU having 16 threads. Ryzen 9 7940HS has 16 MB of L3 cache and operates at 4 GHz by default, but can boost up to 5.2 GHz.
We can see the 7940HS’s threads using any number of utilities such as top.
Many modern computers include processors with different types of cores. For example, some Intel machines have performance cores, efficiency cores, and low power efficient cores. Contrast that with some modern AMD processors housing primary and secondary cores. This isn’t the case with the AMD Ryzen 9 7940HS. Its 8 cores are all the same.
From the lscpu output, we can see all the cores have the same minimum and maximum clock speeds. The entries CPU 0-7 represent the processor’s 8 cores, with CPU 8-15 represent their SMT counterparts.
On the next page, I’ve run a few benchmarks comparing the Zen 4 processor to a Zen 5’s primary and secondary cores. I’ll also compare the results to an Intel competitor.
