Lenovo ThinkStation P3 Tiny Gen 2 Review: NVIDIA-Powered Workstation in a 1-Liter Package

Lenovo has expanded its workstation lineup with the ThinkStation P3 Tiny Gen 2, a compact 1-liter system that bridges the gap between traditional mini-PCs and professional workstations. Following our review of the massive ThinkStation PX, we're examining Lenovo's smallest ThinkStation offering, which brings workstation-class capabilities to an ultra-compact form factor.

Design and Build Quality

The P3 Tiny Gen 2's design philosophy is immediately apparent from its extensive ventilation system. Nearly every surface of the chassis serves as an airflow channel, with perforated panels covering the front, top, and sides. This aggressive cooling approach is necessary given the system's desktop-class components packed into such a small space.

At 179 x 37 x 182.9 mm (7 x 1.5 x 7.2 inches) and weighing just 1.4kg (3.0 lbs), the system lives up to its "Tiny" designation while maintaining a professional black finish that fits seamlessly into office environments.

I/O and Connectivity

The front panel offers a practical selection of ports: two 10Gbps USB-A ports, one 20Gbps USB-C port, and a combo audio jack. Notably, the USB-C port is the only one on the entire system, which may be limiting for users with multiple USB-C peripherals.

Around back, Lenovo maximizes the available space with four USB-A ports (three 10Gbps, one 5Gbps), a 1Gbps Ethernet port using Intel's i219-LM controller, and antenna connectors for the Wi-Fi 7 + Bluetooth 5.4 module. The system includes a single internal antenna, requiring an external antenna for optimal wireless performance.

Graphics and Display Capabilities

Our review unit features the NVIDIA RTX A1000 with 8GB of VRAM, complemented by Intel's integrated graphics. This configuration provides impressive display flexibility for such a small system:

• 4 Mini DisplayPort 1.4a outputs from the NVIDIA card
• 1 DisplayPort 1.4 from integrated graphics
• 1 HDMI 2.1 port from integrated graphics

This allows the P3 Tiny to drive up to six displays simultaneously, making it suitable for multi-monitor workstation setups.

Internal Architecture and Upgradability

Where the P3 Tiny Gen 2 truly distinguishes itself is in its internal architecture. Unlike many 1-liter systems that rely heavily on soldered components, Lenovo has prioritized upgradability:

• Socketed desktop Intel Core Ultra Series 2 CPU
• Removable DDR5 RAM (CSO-DIMM DDR5-6400)
• PCIe expansion slot for additional cards
• 1TB PCIe 5.0 x4 M.2 2280 SSD

The inclusion of a proper desktop CPU socket is particularly noteworthy, as it allows for future CPU upgrades that aren't typically possible in compact systems. This design choice aligns with workstation users' expectations for long-term serviceability.

Power Delivery

Powering this compact powerhouse is a 330W external power supply using Lenovo's proprietary square DC connector. This substantial power delivery is necessary to support the full-power desktop CPU, discrete GPU, and various internal components under load. The system's power consumption can be significant during intensive workloads, exceeding what standardized connectors like USB-C can reliably provide.

Performance Considerations

The combination of a high-performance desktop CPU, dedicated NVIDIA RTX A1000 graphics, and ample cooling suggests the P3 Tiny Gen 2 can handle demanding professional workloads. The system's thermal design appears capable of sustaining performance under load, though we'll need to examine thermal throttling and acoustic performance in our full review.

Market Position

Lenovo positions the P3 Tiny Gen 2 as an entry-level workstation, sitting above the P2 series but below the larger P3 tower models. This positioning makes it an attractive option for professionals who need workstation-class performance but have limited desk space or prefer a cleaner, more compact setup.

Availability and Pricing

The ThinkStation P3 Tiny Gen 2 is available through Lenovo's web store, B&H Photo, and Amazon. Specific pricing varies based on configuration, with our review unit featuring an Intel Core Ultra 9 285 processor, 32GB of RAM, and the NVIDIA RTX A1000.

Conclusion

The Lenovo ThinkStation P3 Tiny Gen 2 represents a compelling fusion of workstation capabilities and mini-PC form factor. By incorporating socketed desktop components and maintaining upgrade paths, Lenovo has created a system that doesn't force users to compromise on serviceability for the sake of size. While the single USB-C port and proprietary power connector may be minor drawbacks, the overall package offers impressive flexibility for professionals seeking powerful performance in a compact footprint.

The system's ability to drive six displays, accommodate future CPU upgrades, and support PCIe expansion cards makes it a versatile choice for various professional applications, from content creation to engineering and scientific computing.
