HP HP Z1 G1i Desktop - Intel Core Ultra 235 (3.4 GHz) Review
The HP Z1 G1i workstation has a powerful 14-core CPU for serious computing, but its integrated graphics hold it back from being a true all-rounder.
The 30-Second Version
The HP Z1 G1i is a capable workstation CPU in a box, hamstrung by weak integrated graphics. Its 14-core Intel Ultra 5 processor is great for heavy computing tasks, but forget about gaming or 3D work. Only consider it if you need a pro-certified chassis and plan to add your own GPU.
Overview
The HP Z1 G1i Tower is a solid, no-nonsense workstation for getting real work done. It's built around Intel's new Core Ultra 5 235 processor, which gives you 14 cores for multitasking and heavy-duty applications.
HP bills this as a machine for designing, editing, and even gaming, but let's be clear from the start: it's a productivity workhorse first. The expandable chassis and pro-level certifications are the real story here, not any flashy gamer cred.
Performance
The 14-core Intel Ultra 5 CPU is the star, landing in the 74th percentile for processing power. It'll handle video editing, 3D modeling, and coding compiles without breaking a sweat. The 1TB PCIe 4.0 SSD is also quick. The big catch is the integrated Intel graphics, which scores in the bottom 37th percentile. That's why its gaming score is a dismal 15.1/100. This is not a machine for rendering or playing modern games.
Pros & Cons
Pros
- Strong 14-core CPU for multitasking and pro apps. 79th
- Fast 1TB PCIe 4.0 SSD for quick file access. 75th
- Reliability scores in the top quartile for a dependable daily driver. 74th
- Good port selection with modern DisplayPort and HDMI outputs. 68th
Cons
- Integrated graphics are a major bottleneck for any GPU-heavy task.
- RAM performance is just average for the category.
- It's heavy and not exactly a looker on your desk.
- The 'gaming' angle in the marketing is wildly misleading.

Value & Pricing
Priced between $1120 and $1190, you're paying for a certified workstation chassis and a powerful modern CPU. If your work is CPU-bound—think data analysis, software development, or audio production—it's a fair deal. But if you need any graphical horsepower, you're wasting money on a platform you'll immediately have to upgrade, which makes the value proposition shaky.
vs Competition
This sits in a weird spot. It's more powerful and expandable than a mini PC like the ROG NUC, but it gets absolutely demolished in gaming by desktops like the HP Omen 45L or Alienware Aurora at similar prices. Compared to a business-focused tower from Lenovo or Dell, the Z1 G1i offers a newer CPU platform, but you sacrifice the dedicated GPU those competitors often include. You're really buying the foundation and the certification here.

Common Questions
Q: Can I upgrade the graphics card in this PC?
Yes, the 500W power supply and workstation chassis are designed for expansion, so adding a dedicated GPU is the intended upgrade path for this model.
Q: Is this good for video editing or 3D rendering?
Only for editing that relies heavily on CPU encoding. The integrated Intel graphics will cripple any GPU-accelerated effects, previews, or rendering, making it a poor choice for serious creative work as-is.
Q: Does it come with Windows 11 Pro?
Yes, it includes a full license for Windows 11 Pro, which is a plus for business users needing features like BitLocker encryption and remote desktop hosting.
Who Should Skip This
Gamers and creative pros should look elsewhere immediately. If you play any modern titles or use apps like Blender, DaVinci Resolve, or AutoCAD, the integrated graphics will be a brick wall. You'd be better off with a pre-built gaming PC or a workstation that includes a dedicated GPU from the start.
Verdict
Buy this if you're a developer, engineer, or business user who needs a reliable, expandable tower with serious CPU grunt for virtualization, compiling, or scientific computing, and you plan to add a professional-grade graphics card later. It's a capable base system for the right person.
