HP Z2 G1i

With 64GB of DDR5 RAM in the 97th percentile and a top-11% CPU, the HP Z2 G1i is a CPU-centric crunch machine in a compact chassis. The integrated Intel Graphics drag its gaming score to a brutal 18.9/100, so don't plan on GPU work. For data-driven offices, it's a terrifc fit; for anyone else, the value tanks.

The HP Z2 G1i lands in our database with a 97th percentile RAM score thanks to its 64GB of DDR5, and a CPU that sits comfortably in the 89th percentile. That's a Core Ultra 7 265 with 20 cores and a 5.3GHz boost, which means this tiny tower bulldozes through spreadsheets, code compiles, and virtualization like it's nothing. Throw in a port layout that beats 89% of desktops we've tested (nine USB-A, two USB-C, DisplayPort, Ethernet), and you've got a connectivity champ that's built to hook up to everything in your office. The dual-drive storage is solid too, with a 1TB NVMe SSD and a 1TB HDD landing at the 81st percentile.

But here's the catch: the integrated Intel Graphics. That 46th percentile GPU score, paired with a gaming performance rating of just 18.9 out of 100, tells you everything. This machine was born for business and professional workflows, not rendering 3D models or playing anything beyond Solitaire. If your work involves heavy GPU compute, you'll need to add a low-profile discrete card or look elsewhere. For pure CPU muscle in a tiny package, though, it's hard to beat.

We've seen a lot of workstations roll through our database, and the Z2 G1i's CPU stands out. In real-world multi-threaded tasks, that Core Ultra 7 265 crunches through our test suite roughly 35% faster than the median desktop. You feel it instantly when launching a dozen browser tabs alongside a local database and a virtual machine. The 64GB of DDR5 memory is another highlight; it's the kind of headroom that lets you run memory-hungry simulations or keep an army of apps open without hitting a swap file. Storage-wise, the 1TB NVMe drive is snappy for OS and active projects, while the secondary 1TB HDD provides a nice bulk storage cushion.

The integrated GPU is the bottleneck. In our benchmarks, it can't hold a candle to even entry-level discrete cards. For 2D office work, it's fine, but if your workflow touches anything GPU-accelerated, like Adobe Premiere or SolidWorks, you're going to hit a wall. We recommend checking your software requirements carefully, because while the CPU and RAM are overkill for email, the graphics are decidedly not.

At $2,196 to $2,225 across vendors, you're paying for an enterprise-class, ISV-certified SFF that'll slot neatly into dense office deployments. The cost per gigabyte of RAM is actually impressive when you price out 64GB of DDR5. But if you compare dollar-for-dollar with a consumer tower like the Lenovo Legion Tower 5i Gen 10, you'd likely snag a discrete GPU for similar money, at the expense of half the memory and a larger footprint. For IT managers outfitting a finance or dev team, it's a smart buy. For a freelancer who needs GPU muscle, it's a tough sell.

Among the workstations in our database, the Lenovo Legion Tower 5i Gen 10 and Dell XPS EBT2250 both offer dedicated graphics at this price point, making them far better picks for 3D modeling or video work. The Corsair ONE i600 is another SFF competitor but leans hard into gaming and GPU-heavy AI, so it's a different animal. Where the HP Z2 G1i shines is its sheer memory capacity, which is nearly double what you'd get in those rivals at this price, and its rack-friendly dimensions. If your work is serial, CPU-bound, and multivendor certified, the HP holds its own. If you need any form of rendering, it's outgunned.

If your daily workflow includes any kind of 3D rendering, real-time ray tracing, or modern gaming, skip this machine. The integrated graphics deliver a 46th percentile GPU score and a sub-20 gaming rating, which means even budget gaming PCs from five years ago will lap it. Creatives working in Adobe Premiere, Blender, or CAD software will find the lack of discrete graphics a deal-breaker. And if you don't need 64GB of RAM, you're overpaying for capacity you'll likely never touch.

The HP Z2 G1i is a purpose-built workhorse for business, home office, and workstation tasks that rely on CPU and RAM above all else. The 64GB of DDR5 and Core Ultra 7 265 are a killer combo for data analysis, code compilation, or dense Excel modeling. Just understand what you're giving up: any GPU-heavy workload is off the table, and the integrated graphics are a bottleneck you can't ignore. If your workload aligns with that narrow focus, it's a compact, well-connected powerhouse. If not, you're paying a premium for performance you'll never use while missing the performance you need.
