Lenovo M Series SFF ThinkCentre M75s Gen 5 SFF Review
The ThinkCentre M75s packs a serious punch with 64GB of RAM and an 8-core CPU into a tiny box. But its weak graphics mean it's only for a specific type of user.
The 30-Second Version
The Lenovo ThinkCentre M75s Gen 5 SFF desktop is a compact productivity beast with an AMD 8700G CPU, 64GB of RAM, and a 2TB SSD. It's fantastic for development, VMs, and office work, but its integrated graphics make it a poor choice for gaming or creative tasks. It's a niche machine that excels in its specific lane.
Overview
If you're hunting for a compact desktop that doesn't skimp on core specs, the Lenovo ThinkCentre M75s Gen 5 SFF is a serious contender. It packs AMD's latest 8700G 8-core processor and a massive 64GB of DDR5 RAM into a small form factor chassis, making it a surprisingly powerful little box for the price. At around $1,700, it's aimed at users who need serious multitasking muscle and future-proofing in a space-saving design, but who aren't planning on heavy gaming. We're talking developers, data analysts, and power users in a home office or quiet corner of a business.
Performance
The AMD 8700G CPU lands in the 64th percentile for desktops in our database, which means it's solidly above average. In practice, those eight cores and 4.2GHz boost clock will chew through compilation tasks, virtual machines, and heavy multitasking without breaking a sweat. Paired with that 64GB of RAM (97th percentile), you can forget about ever running out of memory. The 2TB NVMe SSD (91st percentile) ensures everything loads instantly. The catch is the integrated Radeon 780M graphics, which scores in the 8th percentile. It's fine for driving up to two 4K displays for work, but for gaming, you're looking at low settings on older titles. This is a productivity powerhouse, not a gaming rig.

Value & Pricing
At $1,689, the value proposition is clear: you're paying for top-tier RAM and storage capacity in a compact, business-ready package. You won't find many SFF systems with 64GB of RAM at this price. The trade-off is the anemic graphics and limited upgrade path. If your work is purely CPU and memory-bound, this is a good deal. If you need any graphical horsepower, you'll need to look at towers or spend more.
Price History
vs Competition
This ThinkCentre sits in a weird spot compared to its top competitors. The HP Omen 45L, Dell Alienware Aurora, and Lenovo Legion Tower 5i are all full-sized gaming desktops. They'll crush this ThinkCentre in graphics performance and are far more upgradeable, but they're also much larger, louder, and often more expensive when similarly configured for RAM and storage. The MSI MEG Vision X and Corsair Vengeance a7400 are also gaming-focused powerhouses. The M75s's advantage is its footprint and its out-of-the-box spec for memory-intensive professional work. It's the quiet, compact choice if you know you don't need a discrete GPU.

Common Questions
Q: Is the ThinkCentre M75s good for gaming?
No, it's not good for gaming. With integrated AMD Radeon 780M graphics scoring in the bottom 8% of desktops in our tests, you'll be limited to very old games or low settings on esports titles.
Q: Can you upgrade the graphics card in the ThinkCentre M75s?
Not really. The 310W power supply is too small for any meaningful modern graphics card, and the small form factor case severely limits what physically fits. This system is not designed for GPU upgrades.
Q: Is 64GB of RAM overkill for a desktop?
For most people, yes. But for the ThinkCentre M75s's target user—someone running multiple virtual machines, large databases, or compiling massive codebases—64GB of fast DDR5 RAM is a major performance benefit and a key selling point.
Q: How does the ThinkCentre M75s compare to a gaming PC?
It's the opposite of a gaming PC. Gaming PCs prioritize a powerful GPU; this ThinkCentre has a weak integrated GPU but a strong CPU and huge RAM. It's for different tasks entirely, trading graphics power for memory capacity and a tiny footprint.
Who Should Skip This
Skip the ThinkCentre M75s if you're a gamer, video editor, 3D artist, or streamer. The graphics performance simply isn't there. Also, if you think you might want to upgrade components down the line, the small form factor and limited power supply make that very difficult. In those cases, look at the competitors like the HP Omen 45L or Lenovo Legion Tower 5i, which are built for upgrades and graphical power.
Verdict
So, should you buy the ThinkCentre M75s Gen 5? Yes, but only if your needs align perfectly. Buy this if you're a developer, data scientist, or power user who needs tons of RAM and CPU threads in a small, discreet box, and you have zero interest in gaming or 3D work. The value is in the core specs and the form factor. You should skip it if you ever plan to play modern games, edit video, or do any GPU-accelerated work. The integrated graphics are a hard stop for those use cases, and the small power supply means you can't just slap a graphics card in later.
