HP Z4 G5 Workstation Black

The HP Z4 G5 is a solid CPU-focused workstation with a 10-core Xeon and ECC DDR5. It scores 78.7 for workstation use, but the RTX A1000 GPU is a weak spot. Worth it if you need stability and expandability, just shop around because US prices swing by over USD 3,000.

The Xeon w3-2535 runs at 3.5GHz and can boost to 4.6GHz, which puts it in the 72nd percentile for CPUs in our database. That's solid for multi-threaded work like rendering or simulation. The 32GB of ECC DDR5 at 4800MHz lands in the 78th percentile, so memory-heavy tasks won't choke. The RTX A1000 is the weakest link here, sitting at the 64th percentile. It's fine for CAD and light 3D work, but it's not a card you'd want for serious GPU rendering or AI training. The 1TB PCIe 4.0 SSD is quick and lands in the 74th percentile, though you'll probably want to add more storage if you're dealing with massive datasets.

Against the Lenovo Legion 90Y6003JUS, the Z4 G5 is more of a pure workstation while the Legion leans gaming. The Apple Mac Studio M4 Max will crush it in GPU tasks and efficiency, but you lose the expandability and Windows flexibility. The Dell Aurora DACT1250-7551BLK-PUS is a closer match, though Dell's consumer support can be hit or miss. The MSI Aegis ZS2 is a gaming rig in disguise, so it's not a fair fight for professional workloads. The CLX SET TGMSETRTU5204BM is a wildcard, often cheaper but with less consistent build quality. For raw workstation reliability, the HP holds its own, but the GPU holds it back against the Mac Studio.

Pricing is all over the place. US listings range from USD 4,573 to USD 7,651, which is a USD 3,078 spread for the same machine. That's not a typo. If you're in the US, shop around before you click buy. The lower end of that range feels reasonable for a Xeon workstation with ECC RAM. The higher end? You're paying a premium for convenience. The Newegg listing with fast shipping and top-rated service is the one to watch if you want the best deal without the headache.

The HP Z4 G5 is a proper tower workstation, not some slimmed-down office PC. You get a 10-core Xeon w3-2535, 32GB of ECC DDR5, and an RTX A1000 with 8GB of VRAM. It's built for rendering, simulation, and heavy multitasking, and it looks the part at 14.65kg.

Our database puts it at 78.7 for workstation use, which is strong. The CPU and RAM sit comfortably above average, and the 1TB NVMe SSD keeps things snappy. Just don't expect it to be portable or quiet in a small room.

Skip this if you need serious GPU horsepower. The RTX A1000 will bottleneck you in GPU rendering, AI training, or high-end video editing. Also skip it if portability matters, because 14.65kg is not something you'll want to lug around. And if you're on a tight budget, the price spread means you could easily overpay by thousands if you don't shop carefully.

This is a machine for professionals who need a stable, expandable Windows workstation for CPU-heavy tasks. Architects, engineers, and 3D modelers who live in CAD will feel right at home. If your work leans heavily on GPU rendering or AI, the RTX A1000 will frustrate you. But for multi-threaded CPU work with ECC memory, the Z4 G5 is a dependable workhorse.
