HP HP Z2 G1i Tower Workstation Review

The HP Z2 Tower G1i is a powerful engine sold without wheels. Fantastic CPU and upgradeable chassis, but the lack of any graphics card makes it a non-starter for most. Only buy this if you're installing a specific professional GPU and need ISV certifications.

The HP Z2 Tower G1i is a weird one. On paper, it's a powerful workstation with a 14-core Intel Ultra 5 245K and 32GB of DDR5 RAM, but it ships with integrated graphics. That's the one thing you need to know: this is a blank canvas for professional workloads, not a ready-to-run machine. HP is betting you'll add your own professional GPU, and for the right user, that's a smart play. It's built like a tank for rack environments, has tool-less access for upgrades, and its CPU performance lands in the 80th percentile in our database, which is seriously fast for the price.

The CPU is the star here. That 14-core Intel Ultra 5 245K is no joke, and it shows in our benchmarks. It chews through multi-threaded tasks like a champ. The surprise, and it's not a good one, is the integrated Intel Graphics. With a GPU score in the 37th percentile, this thing is a non-starter for any visual workload out of the box. You're buying a very fast engine with no wheels attached. The cooling system and 600W power supply are clearly waiting for you to bolt on a serious professional GPU.

At $1632, the value is a tough sell for most people. You're paying a premium for workstation-grade construction and ISV certifications, but you get no graphics power. If you need those pro-level stability guarantees and plan to install a specific, certified GPU, it can be worth it. For anyone else, you're overpaying for a fast CPU in a fancy case.

Don't confuse this with gaming PCs like the HP Omen 45L or Alienware Aurora. Those come with powerful GPUs and are meant for play. This Z2 is for work. A closer competitor is something like a Lenovo ThinkStation or Dell Precision tower. The trade-off is that those often come with entry-level pro GPUs pre-installed, but you might pay more for a similar CPU. The Z2's play is offering a top-tier CPU chassis at a lower entry point, assuming you supply the GPU yourself.

If you're looking for a desktop you can unbox and use immediately for creative work or gaming, this isn't it. Go get an HP Omen or a Lenovo Legion tower instead—they'll include a proper GPU and you'll be up and running in an hour.

We can only recommend the HP Z2 Tower G1i to a very specific user: an IT manager building out a rack for CAD, engineering, or scientific computing who needs certified stability and plans to install a fleet of identical, professional GPUs. For an individual professional, a developer, or a small business, buying a desktop with no graphics card at this price is hard to justify. You're better off with a pre-configured workstation that includes a GPU, even a modest one, so you can actually get to work on day one.
