Dell Pro Slim QCS1250 Black 2025

A tiny desktop with a monster CPU and zero gaming ambitions. Great for work, useless for play.

The Core Ultra 7 265K is the star of the show. With 20 cores and a 5.5GHz turbo clock, it chews through heavy multitasking without breaking a sweat. The 32GB of DDR5 at 5600 MHz is a strong pairing, sitting in the 84th percentile, which means you can run a dozen browser tabs, a few VMs, and a big Excel model without hitting a wall. The 1TB NVMe SSD is solid, though not class-leading, landing around the 75th percentile. Boot times and app launches will feel snappy. The surprise, and not a good one, is the GPU. The integrated Intel graphics are fine for pushing pixels to a couple of monitors, but they're a weak spot for anything beyond basic display duties. Don't expect to do any real rendering or gaming on this.

Stacked against the HP OMEN GT22-3080 or the Lenovo Legion Tower 5a Gen 10, the Dell Pro Slim looks like a one-trick pony. Those machines come with dedicated GPUs and are built for gaming and creative work, but they're also bigger, louder, and more power-hungry. The Apple Mac Studio M3 Ultra is in a different league entirely for GPU-bound workflows, but it costs significantly more and locks you into macOS. For pure CPU grunt in a small, quiet, business-friendly package, the Dell holds its own. Just don't expect it to compete on graphics.

At $1,389 USD, this is a fair deal for a business machine with this much CPU power and RAM. You're paying for the processor and the compact form factor, not for graphics or expandability. If your job is CPU-bound, like software development or data analysis, the value is there. If you want a machine that can also play games or handle GPU-accelerated tasks, you're better off spending your money elsewhere.

The Dell Pro Slim QCS1250 is a business workhorse hiding in a surprisingly compact frame. The headline here is the Intel Core Ultra 7 265K, a 20-core chip that lands in the 96th percentile for CPU performance in our database. That's the absolute best right now for a machine in this class. You're getting serious processing muscle for spreadsheets, code compiles, and multitasking, all in a box that won't eat your desk.

But let's be clear about what this isn't. The integrated Intel UHD Graphics 770 is a middle-of-the-pack performer at best, and our gaming score for this thing is a brutal 17.7 out of 100. This is not a machine for after-hours fragging. It's a tool for getting work done, and on that front, it's built like a tank.

If you're looking for a machine that can handle gaming, video editing, or 3D rendering, this isn't it. Go get an HP OMEN GT22-3080 or a Lenovo Legion Tower 5a Gen 10 instead. Those come with real GPUs and won't leave you staring at a slideshow when you try to do anything graphically intensive.

Buy this if you need a compact, reliable, CPU-heavy workstation for business or development work. The Core Ultra 7 265K is a beast, and the 32GB of RAM means you won't be upgrading anytime soon. Skip it if you have any interest in gaming, video editing, or anything that touches a GPU. This is a purpose-built tool, and it's excellent at its purpose.
