HP Z1 G1i 2025

The HP Z1 G1i is a CPU-first workstation with a fantastic port selection and a weak integrated GPU. It's a solid deal for office pros if you can find it near the $1121 mark, but gamers and video editors should look elsewhere. The Core Ultra 5 chip is the real highlight, making this a capable machine for CPU-heavy tasks right out of the box.

The Core Ultra 5 235 is the star here, landing in the 80th percentile for CPU performance in our database. That means it's well above average and will chew through multi-threaded work like code compiles, 3D rendering on the CPU, or heavy data crunching without breaking a sweat. The 16GB of DDR5 RAM is just okay, sitting right in the middle of the pack, so power users will want to budget for an upgrade. The real weak spot is the integrated Intel graphics, which are mediocre at best and drag the gaming score down to a rough 16 out of 100. Don't even think about modern games on this thing without adding a dedicated GPU.

Stacked against something like the Lenovo Legion 34IAS10 or the ASUS ROG GM700TZ, the HP's lack of a dedicated GPU makes it a non-starter for anyone who needs graphics muscle. Those machines are built for gaming and creative work that leans on the GPU. The Dell Tower Plus EBT2250 is a closer fight in the business desktop space, often matching the HP on CPU but sometimes offering better RAM configurations out of the box. The HP's real edge is its port selection, which is top-tier, and its ISV certifications for pro software stability.

Pricing on this thing is all over the map, with a wild spread from $1121 to $2341 across different vendors. At the low end, you're getting a solid CPU and a legit Windows 11 Pro license in a well-built HP chassis, which is a fair deal for a business-focused machine. But if you're looking at the higher end of that range, you're getting into territory where competitors throw in a dedicated GPU and double the RAM. Shop carefully and don't overpay.

HP calls the Z1 G1i a workstation, and with that Intel Core Ultra 5 235 chip and Windows 11 Pro, it definitely looks the part on paper. It's built for folks who need ISV-certified stability for design or editing apps, not for gaming. The spec sheet is a mixed bag: you get a solid 14-core CPU and a fast 1TB NVMe SSD, but the integrated Intel graphics and a modest 500W power supply tell you this machine is all about the CPU grind, not GPU horsepower.

Gamers and video editors should skip this entirely. The integrated Intel graphics are a dead end for any modern gaming or GPU-accelerated rendering, and the cost of adding a decent graphics card plus a new power supply will push you well past the price of a pre-built gaming desktop that's ready to go.

The HP Z1 G1i is a purpose-built CPU cruncher for offices and professionals who value stability and a massive port selection over flashy graphics. It's a smart buy for a software developer, a data analyst, or an engineer running certified apps, provided you snag it at the lower end of its price range. Just know that you're buying a foundation that will likely need a RAM bump and a graphics card down the line if your workload expands.
