Lenovo ThinkCentre M90s Gen 6 2024, Core Ultra 7 265, 32GB, 1TB SSD, Raven Black

The Lenovo ThinkCentre M90s Gen 6 is a premium small form factor business desktop with an excellent 20-core Intel CPU and 32GB of RAM. It's built for multi-monitor productivity and office work, not gaming. Buy it for reliability and performance, skip it if you need a GPU.

The Core Ultra 265 is the star here. With 20 cores and a 4.6GHz boost clock, it lands in the 89th percentile for CPU performance among all desktops we track. That's genuinely impressive for a small form factor machine. In practice, this means heavy multitasking, large Excel files, and even light video editing won't make it flinch. The 32GB of DDR5 RAM sits at the 77th percentile, which is well above average and gives you room to run a pile of browser tabs alongside your actual work apps.

Storage is a 1TB NVMe SSD at the 73rd percentile. It's fast and roomy for a business machine, though not class-leading. The integrated Intel graphics are the weak link, landing at the 52nd percentile. That's fine for driving displays and basic visual tasks, but don't expect to render anything 3D in a hurry. One thing worth noting: multiple buyers specifically mention running three or four monitors off this thing without issues, so the port selection and display output capabilities are doing real work here.

Stacked against the Dell Tower Plus EBT2250, the M90s Gen 6 trades blows on CPU performance but gives up ground on GPU flexibility, since Dell's tower options often include discrete graphics. The HP OMEN GT22-3080 is a completely different animal, it's a gaming machine with a real GPU, so it'll crush the ThinkCentre in any graphics workload but won't match the business-focused reliability and form factor. The Apple Mac Studio M5 Max is the wildcard here. If your workflow is macOS-friendly and you need serious compute in a tiny package, the Mac Studio is a legitimate alternative, though you'll pay Apple prices and lose Windows compatibility.

The CLX SET and Horizon Pcs Autherion Dragon are boutique gaming rigs, so they're not really in the same conversation unless you're trying to do double duty as a gamer and a professional. For pure office productivity and multi-monitor setups, the ThinkCentre holds its own against all of them, but it's not trying to win any spec-sheet wars.

At around $1,839 USD, the M90s Gen 6 is not cheap. You're paying a premium for the ThinkCentre name, the compact-ish chassis, and the enterprise-grade reliability that Lenovo's business line is known for. If you just need raw performance per dollar, a standard tower from Dell or HP will often give you more for less. But if you need a machine that sits quietly in an office, drives multiple monitors, and won't need babysitting, the price starts to make more sense. The CAD price of $3,919 is harder to swallow, but that's the Canadian market for you. Alternatives like the Dell Tower Plus EBT2250 or even a Mac Studio M5 Max (if you're not tied to Windows) are worth a look depending on your needs.

The Lenovo ThinkCentre M90s Gen 6 is a small form factor business desktop that sits in the premium tier of Lenovo's ThinkCentre lineup. It's built around Intel's 20-core Core Ultra 265 processor, paired with 32GB of DDR5 RAM and a 1TB NVMe SSD. Pricing is a bit scattered right now, we see it listed around $1,839 USD in the US and roughly $3,919 CAD in Canada, which puts it firmly in "serious workstation for people who hate downtime" territory.

If you're searching for a reliable office PC that can drive multiple monitors without breaking a sweat, this machine answers that question pretty directly. The integrated Intel graphics won't win any gaming awards, but for productivity, spreadsheets, remote desktop sessions, and general business workloads, it's got plenty of headroom. Lenovo also mentions an optional discrete NPU for AI acceleration, which is a first for this form factor and could matter if your workflow leans on local AI tools.

The M90s Gen 6 scores an 81.7 out of 100 overall in our database, with home office use landing at 86.9 and business at 81.4. Gaming is where it falls off a cliff at 16.6, but that's not really what this box is for. Think of it as a workhorse, not a racehorse.

Skip the M90s Gen 6 if you're a gamer, a video editor working with heavy GPU effects, or anyone doing 3D rendering. The integrated graphics are a hard limitation, and you'd be paying a premium for a machine that can't do what you need. Budget-conscious buyers should also look elsewhere, a standard mid-tower with similar CPU specs will cost less and give you room to add a discrete GPU later. And if you're expecting a truly tiny footprint, the "small form factor" label might disappoint, several owners say it's not much smaller than a regular tower.

Should you buy the Lenovo ThinkCentre M90s Gen 6? If you're running a business, working from home with a multi-monitor setup, or need a dependable Windows 11 Pro machine that won't get in your way, yes. The CPU is genuinely excellent, the RAM is generous, and the build quality is what ThinkCentre buyers expect. It's a set-it-and-forget-it kind of machine.

But if you're looking for anything that involves gaming, 3D rendering, or GPU-heavy creative work, look elsewhere. The integrated graphics are a hard ceiling, and the price doesn't justify the compromise. Same goes if you're on a tight budget, there are cheaper ways to get similar CPU performance in a bigger box.
