Acer Aspire C27 AIO Desktop vs Lenovo ThinkCentre M90a Gen 5 All-in-One

The Lenovo ThinkCentre M90a Gen 5 is the stronger machine: a 20-core Intel Core i7-14700, DDR5 memory that scales to 64 GB, vPro management, wired LAN and a DVD writer. The Acer Aspire C27 counters with a larger 27-inch screen, newer Wi-Fi 6E and a slimmer, quieter home-friendly design. Buy the Lenovo for heavy multitasking, office work and long service life; buy the Acer if screen size and a tidy desk matter more than raw power.

  • Choose the Acer Aspire C27 if you want the biggest screen for everyday browsing, video calls and light work, and prefer Wi-Fi 6E and a slim all-in-one over raw processing power.
  • Choose the Lenovo ThinkCentre M90a Gen 5 if you run many apps at once, need vPro, wired networking and upgradeable memory, and want a business-grade build that will hold up for years.

  • 4.6 / 514 ratings

Questions and answers

Which is better for heavy multitasking?
The Lenovo. Its 20-core Core i7-14700 and DDR5 memory leave the 6-core Ryzen 5 in the Acer well behind when many apps run at once.
Which has the better screen?
The Acer, at 27 inches versus 23.8. Both are Full HD, so the Acer gives more workspace but slightly lower pixel density.
Which lasts longer?
The Lenovo is built for business use, with vPro, a sturdier chassis and memory you can expand to 64 GB, so it stays useful longer.
Is the Lenovo worth stepping up to?
Yes if you do office work, run virtual machines or want upgrade room. If you mainly browse and make video calls, the Acer is enough.
Does either have wired networking?
Only the Lenovo has an RJ45 LAN port. The Acer relies on Wi-Fi 6E, which is newer and faster over wireless.
Which is better for video calls?
The Acer, thanks to its larger screen and built-in 2MP webcam. The Lenovo includes a keyboard and mouse but no webcam is listed.
