Lenovo M Series SFF ThinkCentre M70s Gen 6 SFF Review
The Lenovo ThinkCentre M70s SFF desktop is a mixed bag. It delivers excellent integrated graphics for 4K displays, but its 8GB RAM and small SSD hold it back for real multitasking.
The 30-Second Version
This Lenovo SFF PC has best-in-class integrated graphics but disappointing RAM and storage. Its overall score is mediocre. Only worth buying if you desperately need a tiny PC for a 4K display.
Overview
The Lenovo ThinkCentre M70s Gen 6 SFF is a small business desktop that packs a surprising punch in one specific area. It's built for office environments where space is tight but you still need decent performance for everyday tasks. And honestly, it's not trying to be a gaming rig or a creative powerhouse. It's a reliable, compact machine for spreadsheets, emails, and web apps.
Performance
The performance story here is weirdly split. The AMD integrated graphics are a standout, ranking in the top tier for GPU performance. That means it can handle 4K displays and basic video playback without a hitch. But the rest of the specs drag it down. The 8GB of RAM is underwhelming, the 256GB SSD is small, and the Intel CPU is just about average. It's like putting a sports car engine in a sedan with a tiny fuel tank.
Pros & Cons
Pros
- The integrated graphics are surprisingly capable for an office PC. 95th
- The small form factor saves a ton of desk space. 72th

Cons
- Only 8GB of RAM is a major bottleneck for multitasking. 23th
- The 256GB SSD fills up fast with modern software. 26th
- Overall reliability scores are disappointing.
- It's completely useless for any kind of gaming.

Value & Pricing
At around $782, the value proposition is shaky. You're paying for that excellent integrated graphics and the compact Lenovo build quality, but you're getting seriously skimped on RAM and storage. For a general office PC, you could find machines with more balanced specs for less money. This feels like you're overpaying for one great component while tolerating several weak ones.
vs Competition
Compared to the gaming desktops in our database, like the HP OMEN 45L or the Dell Alienware Aurora, this ThinkCentre is in a totally different world. Those are built for raw power. If you need a compact business PC, look at other SFF options. The Lenovo Legion Tower 5i, while a tower, offers much better balanced specs for a similar price. The MSI Aegis R2 is another gaming-focused option that blows this away in CPU and RAM. This ThinkCentre only wins if your absolute top priority is a tiny box with good video output.
Common Questions
Q: Can I upgrade the RAM and storage later?
Yes, the SFF design is meant to be expandable. You can add more DDR5 RAM and swap or add a larger SSD, though you'll need to check the specific internal layout.
Q: Is this good for light photo editing or video?
The graphics can handle the display, but the 8GB RAM and average CPU will slow you down. For anything beyond very basic edits, it's not recommended.
Q: Why is the GPU score so high if it's not for gaming?
The integrated AMD graphics are excellent for driving high-resolution monitors and handling multiple displays, which is a big plus for office and productivity setups.
Who Should Skip This
Skip this if you're a developer, a power user, or anyone who games. The 8GB RAM will choke your workflow, and the gaming score is dead last. If you need more than a browser and a word processor open at the same time, look elsewhere.
Verdict
Buy this only if you have a very specific need: a supremely compact desktop for a basic office or reception area that must drive a 4K monitor. If that's your exact scenario, it works. For anyone else, especially developers or anyone needing more than two apps open at once, the limited RAM and storage will be a daily frustration.
