Lenovo ThinkCentre M90a Gen 6 Raven Black 2025

A shockingly powerful AIO workstation that's all brains and no gaming brawn. Buy it for the 20-core CPU and 64GB of RAM, not for after-hours fun.

What surprised us most is just how much headroom that Core Ultra 7 chip has. In our database, this CPU sits in the 89th percentile, which means it's a genuine powerhouse for multi-threaded tasks. The 64GB of RAM is a standout, landing in the 96th percentile and making this machine feel practically limitless for professional workloads. The integrated graphics are the obvious bottleneck, scoring a middling 46th percentile, but that's not what this machine is built for. It keeps the desktop silent and cool, letting the CPU stretch its legs without a noisy fan getting in the way.

You won't find many direct competitors in the AIO workstation space, but the Dell Tower Plus EBT2250 and HP Omen GT22 are the ones to watch. The Dell is a traditional tower, so you lose the clean AIO form factor but gain way more upgradeability and likely a better price-to-performance ratio. The HP Omen GT22 is a gaming rig that will run circles around the M90a in any 3D task, but it can't touch this Lenovo's CPU and RAM combo for pure productivity. If your work is all CPU-bound, the M90a is the smarter buy. If you need any GPU muscle at all, skip this and grab the Omen.

Pricing is a bit of a rollercoaster, with a spread from $1939 to $3319 across vendors. At the lower end of that range, this is a seriously compelling package of raw CPU and RAM horsepower for a developer or business user. At the higher end, you're getting into territory where you could build a small form factor PC with a discrete GPU. If you can snag it near that $1939 mark, it's a solid deal. Just make sure you're not accidentally paying a premium for specs you don't need.

The Lenovo ThinkCentre M90a Gen 6 is a business-class all-in-one that's basically a workstation crammed behind a 24-inch screen. The one thing to know is that it's an absolute monster for office and dev work, packing a 20-core Intel Core Ultra 7 and a frankly ridiculous 64GB of DDR5 RAM. If your daily grind involves compiling code, crunching massive spreadsheets, or running a dozen virtual machines, this thing will chew through it without breaking a sweat. Just don't expect to play any games on it after hours.

If you're looking for a machine that can handle even light gaming or GPU-accelerated creative work like video editing, this isn't it. The integrated graphics are a dead end for that. Go get an HP Omen GT22 or a custom-built tower with a discrete GPU instead. You'll sacrifice the AIO form factor but gain the performance you actually need.

The Lenovo ThinkCentre M90a Gen 6 is a purpose-built productivity beast that knows exactly what it is and doesn't apologize for what it isn't. It's a top-tier choice for developers, data analysts, and office power users who need a clean desk and a mountain of CPU cores. The software compatibility grumbles from some users are a minor red flag, but the core hardware is undeniably impressive. If your workflow lives in spreadsheets, code editors, and databases, this is one of the best AIOs you can buy right now.
