Minisforum has officially expanded its NAB series of compact computing solutions with the launch of the NAB3R Mini PC. Released initially in the Japanese market on November 18, 2025, this new entry positions itself as a budget-friendly option within the company's lineup. The device distinguishes itself by integrating the Intel Core i3-1220P processor and offering robust visual output capabilities with support for quad 4K displays.

Alder Lake-P Architecture and Processing Power

The core of the NAB3R’s performance lies in its transition to the Alder Lake-P processor family, a shift from the Alder Lake-H processors utilized in its predecessors, the NAB6 and NAB9. The specific chip selected for this model is the Intel Core i3-1220P, a 12th-generation processor designed to balance efficiency with performance for compact form factors.

Core Configuration and Clock Speeds

The i3-1220P features a deca-core (10-core) configuration, which includes:

• 2 Performance Cores (P-cores): These cores are engineered for demanding tasks and can reach a maximum turbo frequency of 4.4 GHz.
• 8 Efficient Cores (E-cores): These cores handle background tasks and efficiency-focused workloads, capped at a frequency of 3.3 GHz.

This hybrid architecture allows the processor to deliver 12 threads of computing power. While the NAB3R is marketed as an affordable option, the inclusion of a 10-core chip suggests a significant capability for multitasking and general office productivity, surpassing the traditional expectations for entry-level i3 configurations.

Quad 4K Display Support and Connectivity

A defining feature of the NAB3R is its ability to drive multiple high-resolution monitors simultaneously. Minisforum has engineered this compact unit to support up to four 4K displays, making it a viable solution for digital signage, financial trading setups, or productivity workstations requiring expansive screen real estate.

Physical Port Layout

Visually, the NAB3R maintains the design language of the NAB series, closely resembling the NAB6 and NAB9 Plus models. However, Minisforum has introduced subtle changes to the connectivity layout to differentiate the new model.

The front panel features a specific arrangement of ports designed for accessibility:

• USB 3.2 Gen 1 Type-C: A new addition to the front interface, this port is situated between the DMIC (Digital Microphone) and the Type-A ports.
• USB 3.2 Type-A: Two of these ports are located on the front for connecting peripherals.

While the device maintains a compact footprint, sources indicate that the rear of the chassis is "not short of ports," ensuring that the NAB3R retains the connectivity density expected from the NAB series.

Upgradeable Memory and Storage

Despite its compact size, the NAB3R offers expansion options that allow users to tailor the system to their specific requirements. The device supports user-upgradeable RAM and storage, extending the lifecycle and adaptability of the machine.

RAM Specifications

The system supports DDR4 memory, a choice that aligns with its budget-friendly positioning while maintaining reliable performance. Users can install up to 64 GB of DDR4-3200 RAM. This capacity is substantial for a mini PC in this class, allowing for heavy multitasking and the handling of large datasets without memory bottlenecks.

Storage Solutions

For storage, the NAB3R accommodates an M.2 2280 SSD. This standard form factor ensures compatibility with a wide range of NVMe drives, allowing users to select the speed and capacity that best fits their workflow.

Thermal Management and Cooling Systems

Managing heat is critical in small form factor (SFF) computers, particularly when utilizing processors with turbo capabilities like the i3-1220P. Minisforum has implemented a comprehensive cooling strategy for the NAB3R that addresses both the CPU and storage components.

The cooling architecture includes:

• Large Turbo Fan: A substantial fan located on the underside of the chassis facilitates active airflow to dissipate heat generated by the central processing unit.
• Active SSD Cooling: Recognizing that high-speed NVMe drives can throttle under thermal load, Minisforum has included a dedicated active cooling solution specifically for the M.2 2280 SSD.

This dual-approach to thermal management ensures that the device can sustain performance during prolonged use without succumbing to thermal throttling, a common issue in passively cooled or poorly ventilated mini PCs.

Market Positioning and Availability

The launch of the NAB3R represents a strategic move by Minisforum to offer an entry-point into the NAB ecosystem that does not sacrifice essential features like multi-monitor support or expandability. By utilizing the Intel Core i3-1220P, the company bridges the gap between basic office PCs and high-performance workstations.

While the chassis design is largely inherited from the higher-end NAB6 and NAB9 models, the internal shift to the Alder Lake-P platform allows for a more cost-effective price point. The device's release in Japan highlights Minisforum's continued focus on Asian markets, where space-saving computing solutions are in high demand. The combination of a 10-core processor, 64 GB RAM support, and quad 4K output positions the NAB3R as a versatile tool for both commercial and home office environments.
