HP Z2 G9 2024, Core i9-14900K, 32GB, 1TB SSD, RTX A4000

A 24-core i9 in a small box with a pro GPU. Buy it for work, not for play.

The i9-14900K is an absolute monster, sitting in the 95th percentile for CPUs in our database. That's top of the charts territory. 32GB of DDR5 at 4800 MHz is solid, though not bleeding edge, and the 1TB PCIe 4.0 SSD lands right around average for this class. The RTX A4000 is a pro-grade card, not a gaming card, so it's built for CAD, rendering, and simulation work rather than frame rates. What surprised us is how much HP managed to fit in here without thermal throttling becoming a disaster. The 550W PSU is adequate but doesn't leave much headroom if you're thinking about future GPU upgrades.

The Mac Studio M4 Max is the obvious alternative if you're not tied to Windows or NVIDIA. It's smaller, quieter, and Apple's silicon handles creative workloads beautifully, but you lose CUDA support and upgradeability. The Dell Tower ECT1250 gives you more room to grow with a bigger PSU and better cooling, but it's a full tower so you're trading desk space for headroom. The Lenovo Legion and MSI Aegis are gaming-focused machines that'll beat the Z2 in frame rates but fall behind in pro app stability and driver certification.

Pricing is all over the map depending on where you live. US listings hover around $1,849 to $1,949, which feels fair for this spec sheet. The EUR and BRL prices are significantly higher, and at those numbers you should seriously consider alternatives. For US buyers, this is a solid deal. For everyone else, shop around before committing.

The HP Z2 G9 SFF is a workstation that punches way above its size class. You're getting a 24-core i9-14900K and an RTX A4000 with 16GB of VRAM crammed into a small form factor box that won't eat your entire desk. The headline here is simple: near-flagship CPU performance in a package that fits under a monitor. HP redesigned this thing to fit full-height, full-length GPUs, which is rare for SFF machines and honestly kind of impressive.

If you're looking for a gaming machine, this isn't it. Go get a Lenovo Legion or MSI Aegis instead, you'll get way more frames per dollar. And if you're outside the US where prices jump significantly, the Mac Studio M4 Max starts looking like a much smarter buy for creative work.

If you need serious CPU horsepower in a compact chassis and you're doing real workstation tasks, the Z2 G9 SFF is an easy recommendation at US pricing. The i9-14900K alone makes this worth considering, and the fact that HP managed to fit an RTX A4000 in here without it becoming a space heater is genuinely impressive. Just don't buy this expecting a gaming rig, and don't overpay if you're outside the US.
