Minisforum is stepping into the ARM desktop arena with the MS-R1, a compact mini PC built around a heterogeneous 12-core processor and loaded with workstation-grade I/O. Designed for developers, homelab enthusiasts, and anyone curious about ARM on the desktop, the MS-R1 blends low power consumption with surprising expansion options, including a full-size PCIe 4.0 x16 slot.
At the heart of the system is the China-made CIXIN P1 SoC, fabricated on a 6nm process and pairing Cortex-A720 performance cores with Cortex-A520 efficiency cores running between 1.8 GHz and 2.6 GHz. Reports indicate the chip integrates an NPU rated up to 30 TOPS for on-device AI acceleration. Graphics duties are handled by an ARM Immortalis-G710 MC10 GPU, and memory is LPDDR5 for speed and efficiency.
The MS-R1 reuses the compact MS-01 chassis, but swaps x86 silicon for an ARM platform while keeping the same pro-level connectivity. The enclosure measures 196 x 189 x 48 mm and weighs about 1.35 kg, making it easy to tuck into a studio, lab, or edge deployment.
Minisforum ships the system with a custom Linux-based Debian 12 OS and supports installation of standard Debian 12 or 13. That, combined with the uncommon inclusion of a PCIe 4.0 x16 slot (wired x8), makes this one of the rare ARM mini PCs ready for add-in cards, including discrete GPUs or high-performance accelerators. For software developers, ARM testers, and AI/edge workloads, it’s an intriguing, flexible platform.
Memory and storage configurations are straightforward. You can choose 16 GB, 32 GB, or 64 GB of LPDDR5 at 5500 MT/s, or enable ECC to get 12 GB, 28 GB, or 60 GB. Storage options include no SSD, 512 GB, or 1 TB PCIe SSDs.
Connectivity is where the MS-R1 shines. It features dual 10Gb Ethernet for high-speed networking, Wi-Fi 6E and Bluetooth 5.3 for modern wireless, and a broad set of headers for embedded and maker projects, including a 40-pin GPIO, eDP, UART, I2C touch connector, and a TPM header. Power flexibility is also notable, with 100W USB-PD support and an included 180W AC adapter.
