HP Z1 G1i Black

With 64GB of DDR5 in the 96th percentile, the HP Z1 G1i is a memory monster built for professional multitasking. The 20-core Core Ultra 7 CPU is a standout, but the integrated graphics are a major bottleneck, making this a terrible choice for gaming or GPU work. It's a specialized tool that excels at CPU and RAM-heavy tasks, but you'll want to add a dedicated GPU down the line.

The Core Ultra 7 265 is the star of the show here. Its 20 cores make this one of the best CPUs on the market for raw processing, and in our database it's a standout for workstation tasks. Paired with 64GB of fast 5600 MHz DDR5, you can throw massive datasets, complex 3D renders, or multiple virtual machines at this thing and it won't flinch. The memory configuration is near the absolute best right now, which is a huge deal for professionals running memory-hungry certified applications. The 1TB NVMe SSD is well above average for storage speed, ensuring your projects load quickly, though some competitors offer faster Gen 5 drives.

The weak spot is the integrated Intel Graphics. It's a middle-of-the-pack performer at best, ranking in the 46th percentile. For standard office tasks, design work, and code compilation, it's perfectly fine. But any GPU-accelerated workload, from video editing to even light gaming, will feel the pinch. The 18.4 gaming score isn't a surprise, it's a confirmation that this machine has zero gaming ambitions out of the box. You're buying a powerful brain in a big box, but it needs a dedicated GPU to unlock its full potential for visual work.

Stacked against the competition, the Z1 G1i carves out a specific niche. The Lenovo Legion 34IAS10 and ASUS ROG GM700TZ-BS978 are gaming-focused machines that will run circles around the HP in any 3D task thanks to their dedicated GPUs, but they can't touch this 64GB RAM configuration at a similar price point. The Dell Tower Plus EBT2250 is a more direct business competitor, but the HP's port selection and CPU performance give it a clear edge for I/O-heavy professional setups. The MSI EdgeXpert-11SUS is another strong all-rounder, but if your primary need is a CPU and RAM monster for certified pro-apps, the HP's memory advantage is hard to beat right out of the box.

Pricing on the Z1 G1i is a bit of a wild west show, with a spread of over a million dollars across vendors. That's clearly some outlier pricing noise, but the real-world price seems to hover around the $1,935 mark at the low end. At that price, you're getting a top-tier CPU and a massive amount of RAM that would cost a pretty penny to buy separately. The value proposition is strong if your work is purely CPU and memory bound. Just know that you'll need to budget for a dedicated graphics card if your workflow demands it, which will eat into the initial savings.

The HP Z1 G1i is a workstation that puts its money where its mouth is on CPU and RAM. With 64GB of DDR5 landing in the 96th percentile for memory and an Intel Core Ultra 7 265 scoring in the 89th, this tower is built to chew through heavy multitasking and professional apps without breaking a sweat. The 1TB PCIe 4.0 SSD is solid, sitting in the 72nd percentile, so load times won't be a bottleneck for most workflows. But the integrated Intel Graphics are a real anchor, dragging the gaming score down to a rough 18.4 out of 100. This isn't a machine for play, it's a purpose-built tool for getting work done.

At 5.51kg, the Z1 G1i is a hefty tower that's meant to live under a desk, not move around. Connectivity is a strong point, with a port selection in the 93rd percentile. You get a mix of modern and legacy I/O including DisplayPort, HDMI 2.1, two USB-C ports, and a generous nine USB-A ports. The 500W power supply gives you some headroom for future upgrades, which is good because the integrated graphics are the first thing you'll want to swap out if your workload demands more visual horsepower.

Gamers and video editors should look elsewhere unless they plan an immediate GPU upgrade. The integrated graphics deliver a dismal 18.4 out of 100 for gaming, which is one of the worst scores we see for any modern desktop. If your workflow relies on GPU acceleration for rendering, AI, or 3D modeling, this machine will be a frustrating bottleneck out of the box. You're better off with a system that balances its CPU power with a dedicated graphics card from the start.

The HP Z1 G1i is a specialized powerhouse. If your daily grind involves compiling massive codebases, running complex simulations, or juggling memory-intensive professional software, this machine is a top-tier choice. The CPU and RAM combo is one of the best you can get without moving to a much more expensive tier. Just be crystal clear about your needs: this is not a general-purpose PC. It's a workstation brain that's waiting for a dedicated GPU to become a true all-rounder. For the right professional, it's a fantastic foundation.
