Lenovo ThinkCentre M90a Gen 6 Raven Black 2025

A productivity monster with 64GB of RAM and a Core Ultra 7, but the integrated graphics are a buzzkill. Buy it for work, not for play.

The Core Ultra 7 265 is the star here. It sits in the 89th percentile for CPU performance, which means it's faster than the vast majority of desktops we've tested. The 64GB of RAM is even more impressive, landing in the 97th percentile. That's workstation territory. Compiling code, running VMs, juggling 40 browser tabs, this thing doesn't flinch. The 1TB NVMe SSD is solid but not spectacular at the 73rd percentile, which is fine for most people. The integrated GPU is the weak link, sitting right at the 52nd percentile. It's adequate for display output and light tasks, but don't expect any GPU-accelerated magic.

Against the Apple Mac mini M4 Pro, the M90a wins on RAM capacity and integrated display, but loses on raw GPU performance and software polish. The Mac mini is a better choice if you're deep in the Apple ecosystem or need graphics muscle. Against the Dell Tower Plus EBT2250, the Lenovo's AIO form factor is the differentiator. You're trading upgradeability for desk space. The HP OMEN GT22-3080 is a completely different animal, a gaming tower that will destroy the M90a in any GPU-bound task but can't touch its productivity-focused RAM and CPU combo. If you want a clean, powerful office machine, the M90a is the pick. If you want to game or upgrade components later, get a tower.

Pricing is all over the place right now. We're seeing USD 1,589 to USD 2,039 across four US listings, which is a USD 450 spread. That's a huge gap for the same machine. At the low end, this is a genuinely good deal for a 64GB AIO with a Core Ultra 7. At the high end, you're paying a premium for convenience. Shop around and don't pay more than the low USD 1,500s if you can help it. The value proposition is strong, but only if you find the right listing.

The ThinkCentre M90a Gen 6 is a business AIO that punches way above its weight class for productivity. With an Intel Core Ultra 7 265, 64GB of DDR5, and a 1TB NVMe SSD, this thing is built to chew through developer workloads and office multitasking without breaking a sweat. The 94.2 developer score isn't marketing fluff, it's one of the strongest productivity ratings in our database.

But here's the thing. This is not a gaming machine, and the 18.1 gaming score should tell you everything. The integrated Intel graphics are fine for spreadsheets and code compiles, but they'll choke on anything more demanding than Minesweeper. If you need an AIO for work and the occasional YouTube binge, this is a serious contender. If you want to game, look elsewhere.

If you're looking for any kind of gaming performance, this isn't it. The integrated graphics will frustrate you within minutes. Go get a tower with a dedicated GPU instead, like the HP OMEN GT22-3080. Also, if you rely on QuickBooks or older Windows software, the Windows 11 compatibility issues reported by multiple users should give you pause. Test your critical apps before committing.

The ThinkCentre M90a Gen 6 is a fantastic productivity AIO with one glaring weakness: graphics. If your workload is code, spreadsheets, video calls, and general office chaos, this machine will serve you well for years. The 64GB of RAM alone makes it a standout. But if you need any meaningful GPU performance, or if you're sensitive to Windows 11 software quirks, this isn't your machine. For the right buyer, it's a no-brainer. For everyone else, it's a pass.
