Questions and answers

Which is better for photo and video editing?
The Asus NUC 15 Pro+. Its 14-core Core Ultra 5 225H, 16 GB DDR5 and Arc 130T graphics far outpace the Dell's quad-core i3 and 8 GB. The Dell can edit basic photos but will struggle with 4K video.
Is the Asus worth the extra $570?
Yes if you need CPU power, Thunderbolt 4, Wi-Fi 7 or four 4K displays. No if you only browse, email and use Office, where the Dell at $599.99 does the job.
Which is better for a multi-monitor desk?
The Asus. It supports up to four 4K displays through dual HDMI 2.1 and Thunderbolt 4. The Dell has no Thunderbolt and fewer display options.
Can the Dell's 8 GB of RAM be upgraded?
Yes, the Slim Desktop uses DDR5 SO-DIMMs and can be opened for upgrades. Adding RAM closes some of the gap, but the i3 CPU and UHD 730 graphics remain the limit.
Which lasts longer before needing a replacement?
The Asus, because 16 GB RAM (up to 96 GB), a stronger CPU and Thunderbolt 4 keep it useful longer. The Dell is fine for basic tasks but its 8 GB and quad-core i3 date faster.
Which is quieter?
Reviewers describe the Dell as quiet and cool-running. The Asus is a small 0.7 L chassis with a mobile-class CPU, so it can spin up under sustained load.
