HP Z1 G1i 2025

The HP Z1 G1i is a solid workstation foundation with a fast 14-core CPU and best-in-class port selection, but the integrated graphics are a total dud for anything beyond spreadsheets. It's a smart buy if you find it near the $1219 mark and plan to add your own GPU and OS. Pay full retail and you're getting fleeced.

The Core Ultra 5 235 sits in the 80th percentile for CPU grunt, which means it chews through single-threaded CAD tasks and multi-core renders faster than most office PCs. The 16GB of DDR5 is solid but middle-of-the-pack, and you'll want to populate those two empty DIMM slots if you're working with large datasets. Storage lands at the 57th percentile, a snappy 1TB NVMe drive that's fine for OS and apps but tight for video projects. The real weak spot is the integrated GPU, which drags the overall score down hard and makes this machine a non-starter for any 3D visualization work without a discrete card.

Stacked against the Lenovo Legion 34IAS10 or the ASUS ROG GM700TZ, the Z1 G1i looks like a office drone at a LAN party. Those machines come with discrete RTX cards and are built for gaming and creative work, while the HP is a pure productivity tool. The Dell Tower Plus EBT2250 is a closer match, offering similar ISV certs and expandability, but Dell tends to bundle a Windows license and on-site service. The MSI EdgeXpert and CLX SET are wildcards with more consumer-focused configs. If you need a workstation that just works with pro apps and don't care about gaming, the HP holds its own. If you want one machine for work and play, look at the Legion or ASUS.

Pricing on this unit is all over the map, with a $1122 spread between vendors. At the low end around $1219, it's a fair deal for the CPU and expandability you're getting, especially if you already have a Windows license and a GPU lying around. At the $2341 high end, it's a hard pass. You're creeping into territory where competitors throw in a Quadro card and double the RAM. Shop around and don't pay a cent over the lowest listed price.

HP's Z1 G1i is a no-nonsense mid-tower workstation aimed at engineers, architects, and data crunchers who need reliable horsepower without the gaming flash. It packs Intel's new Core Ultra 5 235, a 14-core chip that turbos up to 5GHz, paired with 16GB of DDR5 and a 1TB PCIe 4.0 SSD. You get a frankly ridiculous 11 USB ports, dual DisplayPort, and a tool-less chassis that makes upgrades a breeze.

But let's be real about the integrated graphics. This thing scores a 15.9 for gaming, which is our polite way of saying don't even try. It's built for ISV-certified apps like SolidWorks and Revit, not Cyberpunk. If you need GPU compute, you'll be slotting in your own card, and the 500W PSU gives you some headroom to do that.

If you need any kind of GPU acceleration for rendering, AI workloads, or even light gaming, skip this. The integrated graphics are a dead end, and by the time you add a decent card and a Windows license, you could have bought a pre-built with a Quadro or RTX card for less hassle.

The HP Z1 G1i is a purpose-built workstation for professionals who live in ISV-certified software and need a reliable, expandable tower. It's not flashy, it won't game, and you'll need to bring your own OS. But if you value port count, tool-less access, and a solid 14-core CPU, it's a capable foundation. Just buy it at the right price and plan on adding a GPU and more RAM down the line.
