HP Z2 G1i

The HP Z2 G1i is a small form factor workstation with a strong Intel Core Ultra 5 235 CPU and excellent port selection. It's great for professional productivity and CAD work, but the RTX A400 GPU and 512GB SSD hold it back for heavy graphics or AI workloads. Shop carefully, prices vary by USD 458 between vendors.

The Core Ultra 5 235 is the star here. With 14 cores and a 2.9GHz base clock, it chews through multi-threaded workloads like video encodes and 3D renders without breaking a sweat. Our benchmarks put it in the 78th percentile for CPUs in this category, which translates to strong performance that'll handle most professional tasks without complaint. The 16GB of 5600 MHz DDR5 RAM is solid, though it's sitting right around the middle of the pack at the 56th percentile. For heavy multitasking or large assemblies in CAD software, you might feel the ceiling sooner than you'd like.

The RTX A400 with 4GB of GDDR6 is a workstation GPU, not a gaming card. It's built for stability and certified drivers in apps like SolidWorks and AutoCAD, not for pushing high frame rates in Cyberpunk. At the 61st percentile for GPUs, it's about average for this category. The 512GB NVMe SSD is quick but small, landing at the 44th percentile for storage. You'll want an external drive or a second internal SSD if you work with large project files. The 500W PSU gives you some headroom, but don't expect to drop in a power-hungry GPU later without checking the wattage math.

Against the Lenovo Legion Tower 5a Gen 10, the Z2 G1i trades blows depending on what you need. The Legion is a gaming-oriented tower with more GPU muscle for the money, but it's a full-size desktop that takes up way more space. The HP wins on footprint and port selection, while the Legion likely wins on raw graphics performance. If you're doing CAD or professional work, the HP's workstation drivers and reliability matter more than gaming frame rates.

The Apple Mac Studio M3 Ultra is a different beast entirely. It absolutely demolishes the Z2 G1i in GPU and AI workloads, but it costs significantly more and locks you into macOS. If your workflow is Mac-friendly and budget isn't a concern, the Mac Studio is the better tool. The Dell Tower ECT1250 and ASUS ROG GM700 are both full-size towers that offer more expandability and likely better GPU options at similar price points. The CLX SET TGMSETRTU5204BM is a custom build that may offer better specs per dollar, but without HP's enterprise support and reliability track record. The Z2 G1i's real advantage is that it's small, quiet, and built like a proper workstation, not a gaming rig in a suit.

Value is tricky here because the price swings so much. US listings range from USD 1,763 to USD 2,221, and that USD 458 gap is not pocket change. At the low end, this is a reasonable deal for a compact workstation with a strong CPU and excellent connectivity. At the high end, you're paying a premium for the SFF form factor and HP's build quality. The CAD listing at CAD 2,427 is the only Canadian option we track, so Canadian buyers have less room to negotiate. If you can snag the lower US price, the Z2 G1i makes sense. If you're stuck at the top of that range, you might want to look at alternatives or wait for a sale.

The HP Z2 G1i is a small form factor workstation aimed at professionals who need real computing power without a tower hogging half their desk. It packs an Intel Core Ultra 5 235 14-core CPU, 16GB of DDR5 RAM, and an NVIDIA RTX A400 with 4GB of VRAM into a chassis that weighs about 4kg. HP positions this for 3D design, ray tracing, and other intensive workflows, and the spec sheet mostly backs that up.

If you're searching for a compact workstation that can handle CAD, video editing, or general productivity, this machine sits in a sweet spot. The Core Ultra 5 235 lands in the 78th percentile for CPUs in our database, which means it's well above average for this category. The port selection is genuinely impressive, hitting the 93rd percentile, so you won't be hunting for dongles. But the storage situation is more middle of the pack, and the GPU is fine but not a barn burner.

Pricing is a bit of a rollercoaster. US listings range from USD 1,763 to USD 2,221 depending on the vendor, so shopping around matters more than usual here. That spread is wide enough to buy a decent monitor with the difference.

Skip the Z2 G1i if your work involves heavy GPU rendering, AI model training, or large-scale data processing. The RTX A400 with 4GB of VRAM and the weak AI benchmark score of 34.8 out of 100 make this a poor fit for those tasks. Gamers should also look elsewhere, this is a workstation, not a gaming rig. If you need more storage, the 512GB SSD will feel cramped fast, and you'd be better off with a tower that has room for multiple drives. For those use cases, consider a full-size workstation like the Dell Tower ECT1250 or a custom build from CLX, or if budget allows and macOS works for you, the Mac Studio M3 Ultra is in another league for GPU and AI performance.

Should you buy the HP Z2 G1i? If you need a compact workstation for professional work like CAD, 3D modeling, or general productivity, and you value desk space and port selection, yes. The Core Ultra 5 235 is a genuinely strong CPU, and the port situation is one of the best we've seen in this category. The SFF chassis is a real benefit if you're in a cramped office or home setup.

But if your work leans heavily on GPU compute, AI, or large datasets, this machine will frustrate you. The RTX A400 with 4GB of VRAM is a bottleneck for anything beyond moderate GPU workloads, and the 512GB SSD fills up fast. The AI and LLM score of 34.8 out of 100 is a real weak spot. For those use cases, you'd be better served by a full-size tower with a beefier GPU, even if it means giving up the compact footprint.
