Lenovo’s ThinkStation P3 Tower Gen 2 (starts at $1,499; about $6,766 as tested) delivers the essentials you want in an entry-level desktop workstation, and lets you climb the ladder from there. The P3 starts off affordably priced, and you can tailor it for professional workflows ranging from media creation to AI development—with components like Intel Core Ultra Series 2 processors, ECC memory, flexible storage, and Nvidia RTX Pro GPUs for impressive performance. Want more? The Lenovo gives you quiet operation, straightforward servicing, and a three-year warranty. Though it doesn’t quite scale to the performance of Dell’s Pro Max Tower T2, our current Editors' Choice pick among highly scalable workstation towers, the P3 stands out as a capable alternative for buyers who don’t need to push every bit of the box to the limit.

Configurations: Flexibility for Pro-Grade Builds

The ThinkStation P3 starts with Intel’s Core Ultra Series 2 “Arrow Lake” processors, topping out with the Core Ultra 9 285K. You can also get power-efficient non-K variants, such as the Core Ultra 9 285 in our review unit. Notably, several of these chips support Error Correcting Code (ECC) memory; Intel used to reserve the feature for Xeon chips, but the company has discontinued these server-grade processors in its entry-level workstations.

Versatility is a strength for this ThinkStation. The memory ceiling reaches 256GB in UDIMM or CUDIMM form, with ECC options topping out at 192GB across four upgrade slots. You get accommodating storage as well, with six or seven drives spanning M.2, 2.5-inch, and 3.5-inch formats, including PCI Express 5.0 support.

Graphics options go up to a single Nvidia RTX Pro 5000 Blackwell GPU; if you want a higher-end CPU or GPU, you'll need to upgrade the base 500-watt (500W) power supply to a 750W or 1,100W unit. While Lenovo doesn’t offer the flagship RTX Pro 6000 Blackwell—which you can get in Dell’s Pro Max Tower T2 and HP’s Z2 Tower G1i—the overall component mix meets expectations for this class. Pricing is comparable to the competition, though we won't make any direct comparisons, since companies typically buy these systems through enterprise channels at negotiated prices.

Design: Classic Lenovo Looks, Easy Maintenance

Lenovo’s ThinkStation P3 tower looks professional in the brand’s classic aesthetic, pairing a black rolled-steel case with a honeycomb front panel and unmistakable branding. At 16.3 by 7.1 by 14.6 inches (HWD), it’s compact for a mid-tower, taller but shorter and slimmer than the Dell Pro Max Tower T2 (15.2 by 7.4 by 17.2 inches). The integrated carry handle makes the P3 easier to move than most workstations, and when you pick up the machine, you can feel the build quality—no flex or creaks, just a sense of sturdiness.

The recessed front I/O selection is versatile, including one 20Gbps USB-C port, four USB-A ports (two 5Gbps, two 10Gbps), headphone and microphone jacks, and an SD-card reader. Our unit also features a slimline DVD-RAM drive, though this bay can also accommodate various storage drives.

Around back, the P3 offers two USB 2.0 ports, two 5Gbps USB-A ports, a 2.5Gbps Ethernet jack, and a line-in audio jack. Lenovo’s Flex options allow additional connections, and you can get add-in cards for more specialization. Wireless networking is optional; our unit features Intel’s BE200 card supporting the latest Wi-Fi 7 and Bluetooth 5.4 standards. For monitor output, the RTX Pro 5000 Ada Generation offers the expected four DisplayPort connectors, with an additional HDMI and three DisplayPort connectors on the motherboard.

To get inside the chassis, just remove a couple of thumbscrews and open the left door. Inside, the setup is just as simple: most components, including the GPU, can be serviced without tools. Lenovo’s intuitive red touchpoints make access simple. To take out the optical-drive assembly, for example, all you need to do is press the release handle just behind the drive to slide it out the front. You use a rear release handle to free the rest of the cage and pull it out the side.

The Intel W880-based MicroATX motherboard, meanwhile, offers four DIMM slots. (The W880 chipset enables ECC memory support, although our test model did not come equipped with ECC.) The PCIe 5.0 drive in our review unit (wisely!) comes with a heatsink. The aluminum CPU cooler won't win any glamour awards, but it works adequately for the 65-watt Core Ultra 9 285; Lenovo offers an upgraded model for K-series processors.

Airflow follows a traditional back-to-front pattern. A large front intake feeds a rear exhaust fan and the power-supply fan, while the GPU gets dedicated cooling from two side-mounted 120mm exhaust fans. The assembly detaches without tools, but be careful about the attached cabling before pulling it away. Our unit also leaves space for a 3.5-inch drive beside the power supply.

In daily use, the P3 runs almost silently at idle, with a moderate but unobtrusive noise level under sustained load. The only questionable choice is the side fans, since they exhaust air laterally—a system placed on a desk can end up directing that heat toward the user. The airstream was only lukewarm, in my testing; our unit’s blower-style RTX Pro 5000 Ada Generation GPU sent nearly all its exhaust out the back.

As expected from a workstation in this class, the P3 offers a full range of Independent Software Vendor (ISV) certifications for many professional apps and workflows. (Lenovo maintains a list.) The system includes a three-year warranty with on-site service, with available extended coverage and managed services.

Performance Testing: Scaling to the Skies

We evaluated the ThinkStation P3 Tower Gen 2 in a high-end configuration featuring a Core Ultra 9 285 CPU (24 cores, 5.6GHz turbo), 64GB of DDR5-6400 memory in two 32GB non-ECC UDIMMs, a 1TB PCIe 5.0 SSD, and Nvidia’s RTX Pro 5000 Ada Generation GPU. It runs a clean install of Windows 11 Pro. The RTX Pro 5000 Ada card accounts for the lion's share of the configuration price.

Desktop workstations vary widely by configuration, and none of the systems in our database is a direct match for this P3. We chose a group of machines bracketing the Lenovo in performance on the high and low ends. Dell’s Pro Max Tower T2 delivers a higher-tier configuration with a K-series CPU and RTX Pro 6000 Blackwell GPU. We also included HP’s compact but capable Z2 Mini G1a with its Ryzen AI Max+ mobile processor, Lenovo’s dual-Xeon-CPU ThinkStation PX, and a gaming model that we ran through our workstation tests, the Velocity Micro Raptor Z55a with a Ryzen 7 9800X3D. Except for the last, all rely on a professional GPU; the Z2 Mini's Radeon GPU is part of the Ryzen AI Max+ 395 and employs shared memory. 

Productivity and Content Creation Tests

Our primary overall benchmark, UL's PCMark 10, puts a system through its paces in productivity apps ranging from web browsing to word processing and spreadsheet work. Its Full System Drive subtest measures a PC's storage throughput. 

Three more tests we rely on are CPU-centric or processor-intensive: Maxon's Cinebench 2024 uses that company's Cinema 4D engine to render a complex scene; Primate Labs' Geekbench 6.3 Pro simulates popular apps ranging from PDF rendering and speech recognition to machine learning; and we see how long it takes the video transcoder HandBrake 1.8 to convert a 12-minute clip from 4K to 1080p resolution.

Finally, workstation maker Puget Systems' PugetBench for Creators rates a PC's image-editing prowess through a variety of automated operations in Adobe Photoshop 25.

The P3 soared to near the top of our PCMark test suite, landing just behind the Dell and Velocity Micro systems. Its storage score was closer to middling, but that's due to the specific drive in our test unit rather than any platform limitation. (This configuration still outpaces what we see in many mainstream desktops.)

In CPU-specific testing, the Core Ultra 9 285-equipped P3 largely kept pace with the Dell—impressive, since Lenovo’s system uses a non-K-series CPU. It's a solid sign that the P3 has an effective cooling solution. The ThinkStation PX sits in a different workstation class, but the numbers highlight how a single strong CPU is often a better choice for many workloads. (Cinebench multi-core was the notable exception.) Meanwhile, the HP and Velocity Micro systems proved competitive in the single-core tests but, with just eight cores, simply couldn’t keep up in the multi-core portions. 

Gaming and Graphics Tests

We challenge all systems’ graphics with a quintet of animations or gaming simulations from UL's 3DMark test suite. The first two, Wild Life (1440p) and Wild Life Extreme (4K), use the Vulkan graphics API to measure GPU speeds. The next pair, Steel Nomad's regular and Light subtests, focuses on APIs more commonly used for game development to assess gaming geometry and particle effects. Last up, we turn to 3DMark Solar Bay to measure ray-tracing performance.

These tests use gaming workloads (which workstation GPUs are not optimized for), but they still give a useful relative gauge of a workstation's raw horsepower. The P3’s RTX Pro 5000 Ada Generation trailed Dell’s RTX Pro 6000 Blackwell by a wide margin, which you'd expect, considering Dell’s higher-tier, newer-generation hardware and vast memory pool. The Velocity Micro’s RTX 5090 posted the strongest numbers overall, though its consumer-class drivers are tuned for maximum frame rates rather than the rendering accuracy and stability prioritized in workstation software.

Workstation Tests

First, we measure workstation performance with SPECviewperf 2020 (version 3.1), which renders, rotates, and zooms in and out of solid and wireframe models at 1080p resolution. The three subtests represent PTC's Creo CAD platform, Autodesk's Maya modeling and simulation software for film, TV, and games, and Dassault Systèmes' SolidWorks 3D rendering package.

Next up is Blender, an open-source 3D content-creation suite for modeling, animation, simulation, and compositing. We record the time it takes for Blender 4.2 to render three distinct scenes to measure CPU and GPU rendering performance.

Finally, we also use PugetBench for Creators to test DaVinci Resolve Studio 18 video-editor performance on systems suitable for that challenging app. These automated tasks and features push the CPU and GPU, letting us gauge real-world media-creation speeds.

The P3’s numbers in DaVinci didn’t top the charts, but its configuration is clearly well-suited for video editing. In Blender’s CPU tests, it again proved competitive with Dell’s K-series chip, though it naturally couldn’t compete with the ThinkStation’s PX dual-CPU setup. On the GPU side of Blender and in SPECviewperf, the P3’s RTX Pro 5000 Ada Generation delivered solid numbers, consistently behind the Dell’s higher-class hardware, but within expectations for a GPU of this class.
