HP HP Z2 G1i Small Form Factor Workstation Review

This is a specialist, not an all-rounder. Its 24-core CPU is in the 97th percentile for brute force, but its professional GPU ranks in the 8th percentile for gaming. You're paying for a certified, compact CAD and 3D rendering machine. If that's not your exact need, look elsewhere.

The HP Z2 G1i SFF is a paradox in a small box. It packs an Intel Core Ultra 9 285K, a 24-core CPU that lands in the 97th percentile for raw processing power. That's workstation-grade muscle for rendering, compiling, or heavy simulations. And it's paired with 32GB of fast DDR5-5600 RAM, which sits comfortably in the 82nd percentile. But then there's the GPU. The NVIDIA RTX 4000 Ada is a professional card, and in our gaming-centric database, that puts its performance in the 8th percentile. This isn't a gaming rig. It's a specialized tool for professional 3D, CAD, and engineering workflows, crammed into a 4kg small form factor chassis.

Let's talk about that CPU first, because it's the star. A 97th percentile score means this thing chews through multi-threaded workloads. You're looking at render times and compile speeds that smoke the vast majority of desktops. The 32GB of DDR5-5600 RAM (82nd percentile) is a perfect match, keeping those 24 cores fed without a bottleneck. The storage is solid too, with a 1TB PCIe 4.0 NVMe SSD in the 71st percentile for quick file access. Now, the GPU. The RTX 4000 Ada with 20GB of VRAM is built for stability and precision in professional applications like SolidWorks or AutoCAD. Its drivers are certified for that work. But if you're judging it by gaming frame rates, you'll be disappointed. That 8th percentile ranking tells the whole story. It's a specialist, not a generalist.

With prices ranging from $3941 to $4064 across vendors, you're paying a premium for that professional GPU certification and the SFF engineering. The performance-per-dollar ratio is excellent if your job requires an RTX 4000 Ada for software stability. If you don't need that specific pro card, you can get far more general gaming or compute power for the same money. Shop around, as that $123 spread means you could save a decent chunk by picking the right retailer.

Stacked against gaming desktops like the HP OMEN 45L or Alienware Aurora R16, the Z2 G1i's story is clear. Those systems will demolish it in gaming (its weakest area at 45.4/100) for often less money, thanks to consumer GeForce GPUs. But they lack the driver certification for professional 3D apps. Compared to other workstations, like a Lenovo ThinkStation, the Z2's appeal is its drastic size reduction. You're getting near-tower CPU performance (97th percentile) in an SFF case, but you sacrifice some internal expandability and might pay a size premium for it.

Gamers and general users should steer clear. The data doesn't lie: with a gaming score of 45.4/100 and a GPU in the 8th percentile for that task, this is a terrible value for entertainment. Even content creators using mainstream apps like Adobe Premiere would get better performance from a cheaper system with a consumer GeForce GPU. You're paying a big premium for professional certification you don't need.

We recommend the HP Z2 G1i SFF Workstation specifically for professionals who need a certified, compact powerhouse. The data is clear: unmatched CPU power for the size, great RAM, and the right pro GPU for the job. But we can't recommend it for anyone else. For general use, gaming, or even general content creation, its high cost and specialized GPU are a mismatch. Buy this only if your software vendor lists the RTX 4000 Ada as a recommended card.
