This CPU features eight cores and sixteen threads with a base speed of 3.8 GHz and a boost up to 4.9 GHz. The Zen 4 architecture and 4nm process allow for efficient multitasking and strong single-core performance. You get smooth operation for productivity tools, development work, and general computing tasks without lag. This configuration suits users who need reliable power in a small form factor without the bulk of a traditional tower.

Memory: 24GB LPDDR5X 6400 MT/s

The system includes 24 GB of high-speed LPDDR5X RAM running at 6400 MT/s. This ample capacity handles multiple browser tabs, heavy applications, and virtual machines simultaneously. The high frequency ensures rapid data access, reducing wait times when switching between programs. This setup is ideal for users who run memory-intensive software or keep many applications open at once, providing a responsive experience even under heavy load.

Storage: 1TB PCIe 4.0 SSD

You receive a 1TB solid-state drive using the PCIe 4.0 interface. This provides fast boot times and quick file transfers compared to older SATA drives. The capacity offers plenty of space for your operating system, applications, and large media files. Dual M.2 slots allow for future expansion up to 8TB, making this a flexible choice for users who store significant amounts of data or need rapid access to large projects.

Graphics: AMD Radeon 780M

This integrated GPU features 12 cores running at 2600 MHz, based on the RDNA 3 architecture. It delivers capable visual performance for everyday tasks, video playback, and light gaming. The hardware supports smooth visuals for AAA titles at lower settings and high-resolution displays. This solution eliminates the need for a separate graphics card, saving space and power while still providing enough graphical punch for creative work and casual entertainment.

Display Outputs: Triple Display Support

The unit supports three simultaneous displays via HDMI 2.1, DisplayPort 1.4, and USB4. Each output can drive up to 4K resolution at 240Hz, ensuring crisp and fluid visuals. This versatility is perfect for users who need a multi-monitor setup for productivity, trading, or streaming. You can connect a primary monitor, a secondary screen for reference, and a third for additional content, all while maintaining high refresh rates for smooth motion.

Design and build overview

The Beelink SER9 Pro uses a compact form factor that fits easily into tight spaces. According to the listing, the chassis houses dual M.2 PCIe 4.0 SSD slots under the hood, supporting up to 8TB of fast internal storage. This modular design allows you to expand capacity without opening the case frequently. The unit relies on an MSC2.0 cooling system for efficient heat dissipation. Beelink states it operates at a low noise level of 32 dB. This quiet operation means you can place the Mini PC on a desk near your workspace without distracting fan noise.

The rear panel offers extensive connectivity options. You get one 2.5Gbps Ethernet port for stable wired networking, alongside two USB 3.2 ports and two USB 2.0 ports. A full-function USB4 interface provides 40Gbps bandwidth for high-speed data transfer or docking stations. Display outputs include HDMI 2.1 and DisplayPort 1.4, both supporting 4K at 240Hz. This triple display capability lets you connect multiple monitors for productivity or immersive gaming. Audio features include built-in dual speakers and a microphone chip for 360-degree voice recognition. These integrated components reduce the need for external peripherals, keeping your setup clean and functional.

What you need to know

This unit ships with Ubuntu and OpenClaw. You may need to install Windows or other software if your workflow depends on it.
