Minisforum has detailed the MS-S1 Max Artificial Intelligence desktop, a mini-tower that uses a mobile-on-desktop mainboard and an AMD Ryzen Artificial Intelligence Max+ 395 ´Strix Halo´ processor. The company positions the MS-S1 Max as a straightforward mobile-on-desktop implementation of the Strix Halo platform. The most notable item on the published flyer is the inclusion of USB4 v2 ports rated for 80 Gbps, a capability the article describes as probably the industry first in the client desktop segment.
The article outlines how USB4 v2.0 evolved from the original USB4 specification drafted in 2019 and standardized for the 80 Gbps tier in 2022. USB4 v2.0 introduces a PAM3 coding scheme over the existing pin count rather than simply mapping PCIe Gen 4 physical layers to USB. The standard is designed for backward compatibility with passive cables rated for 40 Gbps while enabling a fixed 80 Gbps per-direction bandwidth when supported. In addition to passive-cable compatibility, USB4 v2.0 specifies an active cable design that can distribute bandwidth asymmetrically between transmit and receive lanes.
The article notes that the active-cable option can enable asymmetric configurations such as 120 Gbps in one direction and 40 Gbps in the other, which could be useful for scenarios like large data transfers to or from portable solid state drives or external GPU enclosures. The piece also draws a direct parallel to Thunderbolt 5, saying the asymmetric bandwidth concept mirrors Thunderbolt 5´s Bandwidth Boost feature that Intel introduced. Beyond the USB4 v2 details, the MS-S1 Max is presented as a typical Strix Halo mobile-on-desktop build with the headline takeaway being early adoption of high-bandwidth USB4 v2 ports in a client desktop product.
