Lenovo ThinkCentre M90a Gen 6 2025, Core Ultra 7 265 vPro, 16GB, 1TB SSD, Raven Black

A fast, sharp, and well-connected office AIO that crushes productivity but can't game to save its life. Buy it for work, not play, and don't overpay.

The Core Ultra 7 265 surprised us. 20 cores and a 4.6GHz boost clock in an all-in-one is no joke, and it lands near the top of the charts for CPU performance. The 16GB of DDR5 and 1TB NVMe SSD keep things snappy, though the RAM is only middle of the pack compared to other desktops. The integrated Intel graphics are fine for productivity and light photo work, but the 48GB of shared VRAM is misleading marketing fluff. It's not a discrete GPU. The 180W PSU tells you everything about the power envelope here. Ports are a strong point, with Thunderbolt, Wi-Fi 7, and a solid mix of USB-C and USB-A. The 120Hz QHD panel is genuinely nice for an office machine.

Against the Apple Mac Studio M3 Ultra, the ThinkCentre loses badly on raw GPU and creative performance, but it costs a fraction of the price and includes a display, keyboard, and mouse. The HP OMEN GT16-0364 and MSI Aegis ZS2 are gaming desktops that will absolutely destroy the M90a in any 3D workload, but they're towers with no screen and no business focus. The Dell Desktop ECT1250 is the closest rival in spirit, but the ThinkCentre's CPU performance and port selection give it an edge for office productivity. If you need an all-in-one for work, this is the one to beat.

Pricing is all over the place, from USD 1,339 to USD 1,979 across four US listings. That's a USD 640 spread for the same machine, which is wild. At the low end, this is a solid deal for a business AIO with this CPU and display. At the high end, you're getting fleeced. Shop around and don't pay more than the low-to-mid range. The best deal in our data is at the USD 1,339 listing, so start there.

The Lenovo ThinkCentre M90a Gen 6 is a business all-in-one that actually feels fast. The Core Ultra 7 265 is a 20-core chip that sits in the 88th percentile for CPU performance in our database, so this thing chews through office work, spreadsheets, and AI-assisted tasks without breaking a sweat. The 23.8-inch 2560x1440 display at 120Hz is a nice touch too, sharper and smoother than most AIOs in this class. The one thing to know? It's a workhorse, not a toy. Gaming performance is a 16.8 out of 100, so don't even think about it.

If you want to play games or do serious GPU work, this isn't it. Go get a tower with a real graphics card, like the HP OMEN GT16-0364 or MSI Aegis ZS2. If you're deep in the Apple ecosystem and need creative performance, the Mac Studio M3 Ultra is the better tool, just bring a much bigger budget.

The ThinkCentre M90a Gen 6 is a fast, well-built business AIO with a great display and excellent connectivity. It's not for gamers, and the Windows 11 software quirks are annoying, but for office productivity, it's a strong buy at the right price. Get it near the USD 1,339 mark and you'll be happy.
