HP Z1 G1i

The HP Z1 G1i tower workstation is a connectivity beast with 14 USB ports and a fast Intel Core Ultra 5 235 that powers through development and office work. Its integrated graphics mean gaming and GPU rendering are off the table without an upgrade, but the wide price spread makes it a steal at the low end and an overpay at the high end.

If you're on the hunt for a no-nonsense workstation that prioritizes raw CPU muscle and more USB ports than you can count, the HP Z1 G1i probably caught your eye. It's built around Intel's new Core Ultra 5 235, a 14-core chip that chews through compile jobs, data crunching, and heavy multitasking. You're getting 32GB of DDR5 RAM clocked at 5600 MHz and a 1TB PCIe 4.0 NVMe SSD right out of the box, all packed into a sober black tower that weighs a hefty 5.51kg. This isn't a slim mini PC, it's a proper desktop that means business.

What makes this machine stand out is the connectivity. We're talking 2x USB-C, a staggering 9x USB-A ports, Thunderbolt, DisplayPort, HDMI 2.1, and good old Ethernet. Seriously, you could plug in your entire desk setup plus a museum's worth of peripherals and still have room. The price is a moving target, though. We've seen it range anywhere from around $1,183 all the way up to $2,536 depending on the vendor, so shopping smart is key.

It's aimed squarely at developers, engineers, and home office users who need reliability and expandability. The Z1 G1i is certified for professional apps, and the integrated Intel Graphics will handle your spreadsheets, code editors, and terminal windows without breaking a sweat. But if you were hoping to fire up Cyberpunk 2077 or do serious 3D rendering on the included GPU, you'll need to recalibrate your expectations hard. This is a workstation through and through, not a gaming rig.

In our database, the Core Ultra 5 235 lands solidly in the upper tier for CPU performance among workstations. It's not the absolute fastest chip we've tested, but it's a strong performer for threaded workloads like compiling large codebases or running virtual machines. Paired with 32GB of fast DDR5 memory, the system rarely stumbles in day-to-day productivity, even with dozens of browser tabs, Docker containers, and an IDE open simultaneously. Boot times and app launches feel snappy thanks to that 1TB NVMe SSD, which scores well within the pack but doesn't set any records.

The elephant in the room is the integrated Intel Graphics. It's fine for displaying desktop apps and driving multiple monitors, but it ranks dead average among all systems we test. That means zero real gaming ability and very limited acceleration for GPU-based rendering or video encoding. The 500W power supply is a saving grace, though. It gives you plenty of headroom to drop in a dedicated card later, transforming this tower into a more versatile machine if your workload ever shifts toward CUDA or gaming.

Value here is a rollercoaster. At the low end of the $1,183 to $2,536 spectrum, you're getting a well-built workstation with a modern CPU and ample RAM for a competitive price. That's a sweet spot for a developer workstation, especially if you value the HP Z series reliability and that port extravaganza. But if you're near the $2,500 mark, the value proposition crumbles. You could snag a system with a dedicated RTX 4060 or better for similar money, so hunting for a deal from the cheaper vendors is absolutely critical. The included keyboard and mouse are fine, but don't expect anything fancy.

Compared to gaming-oriented towers like the ASUS Republic of Gamers GM700TZ or Lenovo Legion Tower 5i Gen 10, the HP Z1 G1i takes a totally different path. Those machines ship with dedicated graphics and flashy RGB, making them far superior for gaming and GPU-heavy creative work. But they often skimp on professional certifications and the sheer number of rear I/O ports HP packs in. The Dell XPS EBT2250 is a closer rival in the workstation space, though Dell's comparable configs tend to cost more and offer fewer USB-A ports.

Then there's the Apple Mac mini M4. It's tiny, silent, and sips power, while delivering CPU performance that can outpace the Core Ultra 5 235 in many creative workflows. But you'll lose the expandability, the ocean of ports, and native Windows if your software stack demands it. The HP's tower form factor and internal bays make it the obvious choice if you plan to add storage, a GPU, or other PCIe cards down the line.

Skip this tower if you're a gamer, a 4K video editor, or a 3D artist. The integrated graphics will be a constant bottleneck. For similar money on the high end, you can grab a Lenovo Legion Tower 5i Gen 10 or an ASUS ROG GM700TZ with a proper dedicated RTX card. Even the Apple Mac mini M4 is a better fit for creative work if you're willing to switch to macOS, and it takes up a fraction of the desk space.

If you need a developer workstation or a rock-solid home office desktop that can handle anything short of 3D rendering, and you want enough USB ports to charge a small army's worth of devices, the HP Z1 G1i is a compelling choice, especially if you find it near the lower end of its price range. The CPU is quick, memory is abundant, and the build quality is what you'd expect from HP's professional line. Just know that the integrated graphics are a limiting factor, and you'll want to plan for a dedicated GPU upgrade if your ambitions ever creep into gaming or visual effects.

For pure office productivity or coding, it's a strong buy. But it's not a do-it-all machine out of the box, and that's okay if you're clear-eyed about what you need.
