実証データ

Performance

The Ryzen 7 PRO 8700G is a solid performer for productivity. Eight cores at 4.2GHz base with boost up to 5.1GHz means snappy multitasking and fast app launches. The integrated Radeon 780M handles everyday graphics fine, but it's not built for serious gaming. Our database puts the CPU in the 71st percentile, which is strong for office work. The GPU sits at the 60th percentile, which is about average for integrated graphics. The 16GB of DDR5 at 4800 MT/s is adequate, though the 512GB SSD lands in the 44th percentile, which is a bit tight if you're storing lots of files locally.

vs Competition

Stacked against the HP OMEN GT22-3080 or Lenovo Legion Tower 5a, this Dell gets absolutely smoked in gaming. Those machines have dedicated GPUs and are built for frame rates. The Apple Mac Studio M4 Max is in a different league for creative work, though it costs way more. The ASUS ROG GM700 and CLX SET are gaming-focused too. The Dell's real competition is other business desktops, not gaming towers. For office productivity, it holds its own. For anything else, look elsewhere.

Value & Pricing

Pricing is all over the place. US listings run from $1,263 to $1,337, while Canadian buyers see CAD 1,881. For a business desktop with integrated graphics, that's on the premium side. You're paying for the PRO processor, Windows 11 Pro, and Dell's reliability. If your company is footing the bill, fine. If it's your own money, you might want to shop around.

詳細情報

Overview

The Dell Pro Tower QCT1255 is a business desktop that knows exactly what it is. AMD's Ryzen 7 PRO 8700G brings 8 cores and a 4.2GHz base clock, paired with 16GB of DDR5 and a 512GB NVMe SSD. It's built for spreadsheets, video calls, and the occasional AI workload, not for fragging noobs on a Friday night.

Dell packed in Wi-Fi 7, Bluetooth, and a healthy port selection including USB-C, HDMI 2.1, and DisplayPort. The 180W power supply tells you everything about the intended use case. This is a quiet, reliable office worker, not a gaming rig in disguise.

Common Questions

Q: Can I upgrade the RAM later?

Yes, the Dell Pro Tower uses standard DDR5 DIMMs. 16GB is fine for most office work, but you can bump it up if you run heavy multitasking or virtual machines.

Q: Will this run modern games?

Not really. The integrated Radeon 780M can handle older or less demanding titles at low settings, but our gaming score of 14.6/100 tells the story. This is a productivity machine, not a gaming rig.

Q: Does it support dual monitors?

Yes. With both HDMI 2.1 and DisplayPort 1.4a outputs, you can run two displays without any extra adapters. The integrated graphics handle dual 4K monitors for productivity work just fine.

Who Should Skip This

Skip this if you want to play games, edit 4K video, or do any serious GPU work. The integrated Radeon 780M and 180W power supply mean no meaningful graphics upgrades. If you need a machine that can grow with you, look at something with a dedicated GPU slot and a beefier PSU. Also skip it if you need lots of local storage, since 512GB goes quick.

Verdict

Buy this if you need a reliable office desktop with solid CPU performance and modern connectivity. The Ryzen 7 PRO 8700G chews through productivity tasks, and Wi-Fi 7 future-proofs your network. Just don't expect to play games on it. The integrated Radeon 780M is fine for video playback and light photo editing, but that's about it.
