Dell Pro Slim QCS1250 2025, Core Ultra 9 285K, 64GB, 1TB SSD, Black

The Dell Pro Slim QCS1250 packs a top-tier Core Ultra 9 285K and 64GB of RAM into a compact SFF chassis. CPU performance is elite, but integrated graphics make gaming a non-starter. Worth it for CPU-heavy work, skip it if you need a GPU.

The Core Ultra 9 285K is the star here. 24 cores at 3.7GHz base, and it's one of the best CPUs we've tracked. Dell claims it outruns the i9-14900K with better efficiency, and our data backs up the speed part. The 64GB of DDR5 is a standout too, landing in the 95th percentile. Compiling code, running VMs, juggling a hundred browser tabs, this thing won't blink. Storage is solid at 1TB NVMe, about average for this class. The weak spot is graphics. Integrated Intel graphics mean dual monitor support is fine for productivity, but don't expect to render 3D scenes or play anything beyond Solitaire without pain.

Stacked against the Lenovo Legion 90Y6003JUS or HP OMEN B91WHAA#ABA, the Dell gets destroyed in graphics. Those machines have dedicated GPUs and are built for gaming or creative work. The Apple Mac Studio M4 Max is in a different league for GPU-accelerated tasks and efficiency, though you'll pay more. The CLX SET and MSI Aegis also offer dedicated graphics at similar prices. The Dell's only real edge is its compact size and that monster CPU. If you need CPU performance above all else and don't care about graphics, it holds its own. Otherwise, the competition offers more balance.

At $2,050 USD, this is a tricky call. You're paying for the CPU and RAM, and those are genuinely excellent. But you're also paying for a machine with integrated graphics and a 180W power supply that won't support a meaningful GPU upgrade later. For a developer or office power user who needs raw CPU grunt and lots of memory in a small footprint, it's reasonable. For anyone who wants a balanced system, that money goes further elsewhere.

The Dell Pro Slim QCS1250 is what happens when Dell stuffs a Core Ultra 9 285K and 64GB of DDR5 into a small form factor box meant for actual work. It's the next-gen OptiPlex, and it shows. You get a 24-core CPU that lands in the 97th percentile of our database, a full terabyte of NVMe storage, and Windows 11 Pro out of the box. This is a workstation in office clothing.

But let's be real about the graphics. Intel integrated graphics sit at the 51st percentile, which is fine for spreadsheets and code but a joke for anything resembling modern gaming. The gaming score of 16.3 out of 100 tells you everything. This machine is built for productivity, not play.

Skip this if you do any gaming, video editing, 3D modeling, or GPU-accelerated work. The integrated graphics and 180W PSU mean you can't fix that later. Also skip it if you want a balanced system for the money. At $2,050 USD, you can get a machine with a real GPU that will serve you better for mixed workloads.

Buy this if you're a developer, data cruncher, or office power user who needs top-tier CPU performance and tons of RAM in a small, quiet box. The Core Ultra 9 285K and 64GB of DDR5 are the whole story here. If you need any kind of GPU muscle, even light gaming or video editing, this isn't your machine. It's a specialized tool, not an all-rounder.
