Lenovo ThinkStation P3 Tiny 2025, Core i9-14900, 64GB, 2TB SSD, Quadro T400, Black

A 24-core i9 in a box the size of a sandwich. Just don't expect the GPU to keep up.

The CPU is a monster. 24 cores at up to 5.8GHz boost, and it lands in the 86th percentile for mini PCs. That's genuinely impressive for a box this small. The 64GB of DDR5 is also top-tier, sitting in the 95th percentile. But the T400 GPU is the bottleneck. It's a 56th percentile part, which means it's fine for basic CAD work and driving displays, but don't expect to run modern games or heavy AI workloads. Our database shows the ai_llm score at 49.3 out of 100, which is a real weak spot. The 2TB NVMe SSD is fast and roomy, and the port selection is solid with DisplayPort, HDMI, USB-C, and six USB-A ports.

Against something like the HP OMEN GT22-3080 or ASUS ROG GM700, the ThinkStation P3 Tiny is a completely different animal. Those are gaming towers with real GPUs. The P3 Tiny is a professional workstation that prioritizes CPU and RAM over graphics. If you need CUDA cores for rendering or machine learning, the T400 will frustrate you. But if you're running VMs, compiling code, or doing office work with a dozen browser tabs, the P3 Tiny crushes those gaming rigs in CPU-bound tasks while using a fraction of the desk space.

Here's the thing: this exact config ranges from USD 1,541 to USD 2,776 across six US listings. That's a USD 1,235 spread for what appears to be the same machine. If you're paying the high end, you're getting fleeced. At the low end, it's a compelling compact workstation. But you need to shop around. The Best Buy listings with the USB hub bundle seem to be the sweet spot, but double-check the exact RAM and storage config before you click buy.

The Lenovo ThinkStation P3 Tiny is a weirdly powerful little box. You get a 24-core i9-14900 and 64GB of DDR5 crammed into a 1.41kg chassis that barely takes up desk space. That's the headline: workstation muscle in a package you could hide behind a monitor. But the GPU is a Quadro T400 with 4GB of VRAM, and that's where the story gets complicated.

If you're looking for a gaming rig or anything that needs real GPU power, this isn't it. Go get an HP OMEN or ASUS ROG tower instead. The T400 will leave you frustrated the first time you try to render a scene or run a modern game at decent settings.

The ThinkStation P3 Tiny is a niche product that nails its niche. It's a compact, quiet, professional workstation with a top-tier CPU and tons of RAM. The T400 GPU is the compromise you make for the form factor. If you need real graphics horsepower, buy a tower. If you need a tiny box that chews through CPU-heavy work, this is one of the best options out there right now.
