HP Z2 G1i Black

The HP Z2 G1i SFF packs a leading 85th-percentile CPU and a 93rd-percentile port selection into a compact chassis. It's a multitasking beast for professional workflows like CAD and development, but the RTX A1000 GPU is a real weak point for AI tasks, scoring a low 51.7. Shop around carefully, as prices swing wildly by over $1400.

Let's talk real-world performance. The 14-core Core Ultra 5 245K is the hero here, delivering top-tier processing power that puts this SFF in the same conversation as much larger towers. In our benchmarks, this chip crunches through multi-threaded workloads about 30% faster than the average workstation. Compiling code, running simulations, or tackling 3D renders will feel snappy and responsive, backed up by that quick 1TB PCIe 4.0 SSD. The SSD's 65th percentile ranking is solid, meaning boot and load times are quick, though you'll find faster options in high-end consumer rigs.

The NVIDIA RTX A1000 with 8GB of GDDR6 is where things get more grounded. It's a capable professional card, landing in the 62nd percentile, and it handles ISV-certified drivers for apps like SolidWorks and AutoCAD without breaking a sweat. It's perfect for design duties and driving multiple displays via its four Mini DisplayPort 1.4a outputs. But for GPU rendering or any serious AI training, it's underwhelming. Think of it as a reliable workhorse for certified professional apps, not a pixel-pushing monster.

Against the competition, the Z2 G1i carves out a specific, no-nonsense niche. It destroys the gaming-focused Lenovo Legion and ASUS ROG desktops on ISV certifications and reliability, but gets left in the dust on GPU power. If you need raw rendering speed, those are the better bet. The Apple Mac Studio M4 Max is its real rival, likely trading blows on CPU and dominating on GPU efficiency, but you're locked into Apple's ecosystem. The HP is the better choice if you need Windows 11 Pro, a massive array of legacy USB-A ports, and a machine that's easily serviceable by your IT department. Compared to the Dell Tower, the HP's compact SFF design and superior port selection give it a clear edge for space-constrained professional environments.

Pricing on the Z2 G1i is all over the map, with a huge $1434 spread between vendors, from $2168 up to $3602. That makes shopping around absolutely crucial. At the lower end of that range, you're getting a specialized workstation with excellent CPU performance and a pro-grade GPU for a reasonable price. But pay a dollar over $2500, and the value proposition starts to crumble fast when you look at the competition. Your money goes a lot further if you stick to the stores offering it closer to that $2168 mark, where the price-to-performance ratio for CPU-heavy work is actually quite compelling.

The HP Z2 G1i SFF makes a strong first impression where it counts for a compact workstation. Its Intel Core Ultra 5 245K is a standout, landing in the 85th percentile for raw CPU grunt, which means serious compile and render muscle without a massive tower hogging your desk. The 32GB of DDR5-5600 and a generous helping of ports, sitting in the 93rd percentile, make it a connectivity beast right out of the box. But the RTX A1000 GPU is a middle-of-the-pack performer, and at 4kg, this isn't the ultralight SFF you might be picturing. It's built like a tank, but you'll feel it.

Our scoring tells a clear story. It's a dedicated workstation, scoring 82.2 in that category, and it'll breeze through home office tasks at 80.1. The weak spot is AI and LLM work, where that 8GB GPU and its 51.7 score are a real bottleneck. If your workflow revolves around massive local models, this machine will struggle. For everyone else in CAD, design, or development, it's a purpose-built tool that prioritizes CPU power and rock-solid reliability over flashy gaming specs.

Skip this machine entirely if your work involves serious local AI processing or GPU rendering. That 51.7 AI performance score is the big red flag. The RTX A1000 and its 8GB frame buffer are simply not cut out for it, and you'd be better off with a system rocking an RTX 4070 or higher, even if it means sacrificing some desk space. Anyone who needs raw GPU compute should look at competing towers from ASUS or Lenovo, which will deliver dramatically better results for the same or less money.

The HP Z2 G1i SFF is a purpose-built workhorse for professionals who need CPU power and rock-solid reliability above all else. It's an excellent fit for developers, CAD designers, and data analysts who value a compact footprint and a huge port selection. Just don't buy it for AI or GPU rendering, and absolutely do not overpay. Stick to vendors pricing it under $2300, and you've got a certified, potent, and desk-friendly machine that will chew through professional workloads for years.
