Minisforum MS-S1 MAX-P495 Brings 192GB Unified Memory to a Mini AI Workstation

Minisforum’s MS-S1 MAX-P495 is not being positioned like a regular compact desktop. It is a small-form-factor AI workstation built around AMD’s Ryzen AI Max+ PRO 495, and it pushes the mini PC category toward local inference, model testing, creative production, and edge AI work. Minisforum unveiled the machine at IFA 2026 in Berlin on September 4, 2026, alongside the AI Agent NAS N5 MAX-P495, with both systems designed around the same AMD platform. Tom’s Hardware covered the launch that day and noted that pricing was not available at the time; as of September 28, 2026, Minisforum’s US store lists the MS-S1 MAX-P495 at $7,399 with a 192GB RAM + 2TB SSD configuration and an estimated shipping window of mid October.

The headline spec is the memory pool. Minisforum lists the MS-S1 MAX-P495 with 192GB of 256-bit LPDDR5x unified memory running at up to 8533MT/s, with up to 160GB allocatable as VRAM. That is the part that makes the system interesting for local AI users: instead of a small GPU VRAM limit, the CPU and integrated graphics share a much larger memory space. The processor itself is listed as a 16-core, 32-thread AMD Ryzen AI Max+ PRO 495, with a 3.1GHz base frequency, up to 5.2GHz max turbo, Radeon 8065S integrated graphics, 40 graphics cores, and up to 55 TOPS from the NPU or 131 TOPS overall.

The MS-S1 MAX-P495 also leans into connectivity rather than chasing the thinnest possible chassis. Minisforum lists dual 10GbE LAN using Realtek RTL8127 controllers, Wi-Fi 7, Bluetooth 5.4, two front USB4 40Gbps ports, two rear USB4 V2 80Gbps ports, HDMI 2.1 FRL, USB 3.2 Gen2, USB 2.0, dual digital microphones, and a 3.5mm combo jack. Storage comes through two M.2 2280 NVMe slots: one PCIe 4.0 x4 slot and one PCIe 4.0 x1 slot, each supporting up to 8TB, with RAID 0/1 support. There is also an internal PCIe x16 physical slot wired as PCIe 4.0 x4, giving the box some room for specialized expansion cards. (store.minisforum.com)

This is still a compact machine, but the power and cooling details show that it is meant for heavier sustained tasks than a basic mini PC. Minisforum lists three power modes: 120W Performance, 95W Balanced, and 60W Quiet. The cooling setup includes a six-heatpipe radiator with PCM and two turbo fans. The chassis measures 222.1 × 206.3 × 77.1mm and weighs 2.8kg, so it is much smaller than a tower workstation while still leaving enough physical space for serious I/O and airflow. Minisforum also mentions horizontal rack deployment and cluster-style management features, which fits the idea of using multiple compact nodes for AI development or edge compute labs.

The MS-S1 MAX-P495 is best viewed as part of a broader shift: mini PCs are moving from simple office desktops to compact AI workstations with unified-memory designs. That does not mean it replaces every GPU workstation, and no independent review should be assumed from the announcement specs alone. Still, the combination of 192GB unified memory, Radeon 8065S graphics, 55 TOPS NPU acceleration, dual 10GbE, fast USB4, and a small desktop footprint gives local AI developers, researchers, and power users a new type of PC to consider. It is especially relevant for people who want to keep models and data on-site, test AI applications locally, or run demanding creative workflows without dedicating space to a full-size tower.
