Lenovo ThinkCentre 625 2025, AMD A, 16GB, 1TB SSD, Black

The 1TB SSD and 16GB of RAM are nice, but the single-core AMD A Series CPU ranks dead last in our entire database. The fanless design and tiny 1-liter chassis are genuinely impressive for quiet, space-constrained deployments. Just don't expect this to feel fast for everyday computing, and shop carefully because European prices swing by EUR 328 between vendors.

Let's talk about that CPU, because it's the elephant in the room. A single-core AMD A Series running at 2.4GHz lands at the 0th percentile in our database. That means every other mini desktop we've tested outperforms it. For context, the 16GB of DDR4 RAM is only at the 32nd percentile, which is mediocre for this category. The 1TB NVMe SSD is solid, landing at the 54th percentile, and it's the main reason boot times and app launches feel snappy on a fresh install.

The integrated Radeon Graphics with 48GB of shared VRAM allocation is a weird spec to see at the 99th percentile. It's not a gaming GPU by any stretch, and the gaming score of 18.8 out of 100 confirms that. What it does mean is that for basic display output, including dual monitors via DisplayPort, this thing handles desktop work without breaking a sweat. Just don't expect to render anything more demanding than a spreadsheet. The fanless design means zero noise, which is genuinely nice for quiet offices, but it also means the chip has to throttle hard under sustained load.

Stacked against the Apple Mac mini M4, this ThinkCentre gets embarrassed on raw compute. The Mac mini's M4 chip is in a completely different universe than a single-core AMD A Series. The Minisforum UM760 Slim and GMKtec Nucbox K8 Plus both offer dramatically better CPU performance in similarly compact chassis, often at comparable or lower prices. The Dell Tower Desktop ECT1250 and HP OmniDesk M02-0234 are traditional towers, so they're not direct form-factor competitors, but both will run circles around this machine for everyday tasks. Where the ThinkCentre wins is the fanless design and enterprise-grade durability ratings, which none of those competitors match. If silence and physical toughness are your top priorities, this has a niche. If you want a responsive computer, look elsewhere.

Pricing is all over the map depending on where you shop. In the US, you can grab this for $373, which is reasonable for a 1TB SSD and 16GB of RAM in a fanless chassis. But European buyers face a wild spread from EUR 677 to EUR 1,005 across four listings in Germany, Spain, France, and Italy. That's a EUR 328 gap for the same hardware, which is frankly absurd. At the low end of that range, it's a defensible thin client purchase. At the high end, you're paying Apple Mac mini M4 money for a CPU that ranks at the absolute bottom of our charts. Shop around before you commit.

The headline number here is a 0th percentile CPU score. That's not a typo. The AMD A Series 1-core chip in this ThinkCentre is, according to our database, dead last among every mini desktop we track. But before you close the tab, the GPU sits at the 99th percentile, which sounds impressive until you realize it's integrated Radeon Graphics sharing system memory, not a discrete card. The 1TB SSD and 16GB of DDR4 RAM are the real bright spots, giving this little box a 62.3 out of 100 overall score.

Lenovo markets this as a thin client for business deployments, and that's the right frame. It's fanless, runs silent, and handles temperature extremes from -20 to 60 degrees Celsius. The 1-liter chassis is genuinely tiny, 96% smaller than a traditional tower. But the customer rating sits at 3.5 out of 5 stars across 994 reviews, and our sentiment analysis shows a split: plenty of happy office users, but a vocal group reporting slowness so bad the machine is nearly unusable for basic tasks.

If you want a responsive general-purpose computer, skip this. The 0th percentile CPU score means even basic multitasking can feel sluggish, and multiple verified owners report lag so bad the machine is nearly unusable. Gamers should obviously look elsewhere given the 18.8 out of 100 gaming score. And if you need lots of ports, the 33rd percentile connectivity ranking means you'll be reaching for dongles. Anyone buying in Europe should also be wary of the EUR 328 price spread, paying over EUR 900 for this hardware is a bad deal when the Mac mini M4 and Minisforum UM760 Slim exist.

The ThinkCentre M625 is a purpose-built thin client, and it succeeds at that narrow job. The fanless design, TPM security, and rugged temperature tolerance make it a reasonable choice for kiosk deployments, healthcare terminals, or dusty warehouse stations where silence and physical durability matter more than raw speed. But the 0th percentile CPU score is impossible to ignore. For general home or office use, the 62.3 overall score reflects a machine that will frustrate anyone expecting snappy everyday performance. The 3.5-star customer rating with reports of severe lag on basic operations backs that up. Buy it for the right job, not as a general-purpose desktop.
