The Minisforum AI X1 Pro is a powerful mini PC based on an AMD Ryzen AI 9 HX 370 with integrated Radeon 890M.
The AMD Ryzen AI 9 HX 370 came to market in the third quarter of 2024. It has 12 cores and 24 threads, consisting of 4 Zen 5 cores, and 8 Zen 5c cores.
The Zen 5c cores are density-optimized “compact” versions of the Zen 5 architecture, primarily used in high-core-count server processors to increase total core counts and maximize data center efficiency. They are distinct from the standard Zen 5 cores, which are designed for general-purpose and HPC workloads, by using a smaller footprint on a denser 3nm process node to achieve higher core densities
We can see the 12 cores / 24 threads using top (or similar utility e.g. htop). Here’s an annotated extract from top.
top lists the 4 Zen 5 cores as %cpu0 to %cpu3, and the 8 Zen5c cores as %cpu4 to %cpu11. The remaining cpu entries are the corresponding threads. While I’ve labelled them as HT, technically AMD doesn’t call them hyperthreading but by the more generic term of SMT (Simultaneous MultiThreading).
My annotated image is confirmed with the lscpu command as this shows the maximum clock frequencies for the Zen 5 and Zen 5c cores. The Zen 5 cores have a higher maximum clock speed.
On the next page, I’ve run a few benchmarks forcing them to run on the different cores, and comparing the results to an Intel competitor.
