HP Z4 G5 Z4 G5 Workstation 1 x Review

This HP Z4 G5 configuration has a CPU in the 9th percentile, making it painfully slow for a $2,347 workstation. You're paying for the expandable platform and reliability, not the components inside it. Only consider this if you're treating it as an empty chassis for a serious custom professional build.

The HP Z4 G5 Workstation is a bit of a puzzle. At $2,347, it's pitching itself as a professional-grade machine, but the core specs tell a different story. You're getting a 6-core Intel Xeon W3-2423 with a base clock of just 2.1GHz, which lands in the 9th percentile for CPU performance in our database. That's a tough starting point for a 'workstation'.

On the plus side, it's built on a solid foundation. The Intel W790 chipset and tool-less chassis offer serious expandability for future upgrades, and its reliability score sits in a respectable 76th percentile. But as it sits on the shelf, you're paying a premium for a platform, not for the performance inside it.

Let's be blunt: the performance out of the box is underwhelming for the price. That Xeon W3-2423 CPU, while stable and ECC-capable, is in the bottom 10% of processors we track. For heavy multi-threaded workloads, you'll feel that 2.1GHz base clock. The NVIDIA T1000 4GB GPU is a basic professional card, scoring in the 48th percentile. It's fine for driving multiple displays and light CAD, but it's not touching serious simulation or AI work. The 16GB of DDR5 RAM is middle-of-the-pack (53rd percentile), and the 512GB SSD is frankly small for a workstation, ranking in the 23rd percentile for storage. This config is a foundation, not a finished product.

The value proposition here is tough. At $2,347, you're paying a workstation premium for entry-level components. You're essentially investing in the HP Z4 platform's reliability and expandability. For the same money, a high-end consumer gaming desktop would obliterate it in raw CPU and GPU performance. The value only makes sense if your workflow absolutely requires ECC memory, multiple professional GPU slots, or other certified workstation features, and you plan to upgrade the core components yourself immediately.

Stacked against its listed competitors, the Z4 G5 in this configuration struggles. The HP Omen 45L or Dell Alienware Aurora at a similar price point would pack a Core i7 or i9 and an RTX 4070-class gaming GPU, offering CPU and GPU performance in the 80th+ percentiles for general and rendering tasks. They lose on ECC memory and certified drivers but win massively on out-of-the-box power. Even a Lenovo Legion Tower with an i7 would be a faster daily driver. The Z4's advantage is its upgrade path and professional stability, not its starting specs.

Gamers and anyone needing high out-of-the-box performance should look elsewhere. With a gaming score of 43.1/100 and a CPU in the 9th percentile, this machine will feel sluggish in games and demanding creative apps. Also, avoid it if you need a compact PC—it scores 34.3/100 for size. This is a niche tool for those building a specific, upgradeable professional system.

We can't recommend this specific HP Z4 G5 configuration as a ready-to-use workstation. The 9th-percentile CPU and modest other specs don't justify the $2,347 price tag for performance today. However, if you need the W790 platform's expandability, ECC support, and proven reliability (76th percentile) as a base for a custom build—and you're planning to install your own CPU, GPU, and more storage immediately—it could be a sensible, if expensive, foundation. For everyone else, a powerful consumer desktop or a pre-configured workstation with better specs will be a better buy.
