This ARM-Based Mini PC Sports a Full X16 PCIe Slot for Discrete GPUs - Minisforum Says "Desktop ARM" Starts Now, but Can It Live up to the Hype?

Why It Matters

By delivering a full‑size PCIe slot on an ARM platform, the MS‑R1 opens the door for energy‑efficient GPU acceleration and AI inference in a mini‑PC form factor, challenging the dominance of x86 desktops in niche workstation and edge‑computing markets.

Summary

Minisforum unveiled the MS‑R1, its first ARM‑based mini PC built around a 12‑core Cixin P1 SoC (eight Cortex‑A720 and four Cortex‑A520 cores) that can boost to 2.6 GHz and includes an Immortalis‑G720 MC10 integrated GPU. The compact 1.7‑liter machine supports up to 64 GB of LPDDR5‑5500 RAM, starts with a 1 TB NVMe SSD and can expand to 8 TB via PCIe 4.0 M.2/U.2, and most notably offers a physical PCIe x16 slot (electrically x8) for discrete GPUs, high‑speed NICs or storage. Pricing begins at $503 for a 32‑GB model and tops out at $695.90 for a 64‑GB/1 TB configuration, positioning the device as a low‑power, AI‑ready workstation for space‑constrained environments.
