HP mt440 G3 Mobile Thin Client 14" Review

This is one of the slowest laptops we've ever tested, with a CPU in the 2nd percentile. At $790, it's a hard sell unless you need a dedicated thin client for work. It's compact and runs Linux ThinPro well, but that's about it.

The HP mt440 G3 Mobile Thin Client is a $790 laptop that makes some very specific trade-offs. It's built for one thing: connecting to a virtual desktop or cloud workspace. Under the hood, you're looking at a 5-core Intel Celeron 7305 processor, 8GB of DDR4 RAM, and a 256GB SSD. Those specs land it near the bottom of our performance charts, but that's by design for a thin client.

Where it does stand out is in its compact size, ranking in the 74th percentile for portability. It's a lightweight 1.48kg machine with a 14-inch 1080p screen and WiFi 6E. The catch is that you're not buying a traditional laptop. You're buying a dedicated terminal that runs Linux ThinPro, an OS meant for accessing remote resources, not running heavy apps locally.

Let's be clear: this isn't a performance machine for local workloads. Its CPU ranks in the 2nd percentile against all laptops in our database, which means it's one of the slowest we've seen. The 5-core Celeron is fine for streaming a remote desktop session or handling basic web tasks, but don't expect to compile code or edit videos on this thing. Its integrated Intel UHD Graphics are similarly middle-of-the-pack, ranking in the 53rd percentile. It'll drive the display and decode video streams, but that's about it.

Memory and storage are weak spots, ranking in the 12th and 13th percentiles respectively. The 8GB of RAM is the bare minimum for modern multitasking, and the 256GB SSD is small by today's standards. For its intended use as a thin client, these specs are probably sufficient, but they leave zero headroom for anything else.

At $790, the value proposition is incredibly niche. You're paying a premium for a device with bottom-tier performance components because it's built as a dedicated business terminal. For the same money, you could buy a consumer laptop with significantly better specs for local work. The value only makes sense if your IT department mandates thin clients for security and manageability, and even then, the price feels steep for the hardware you get.

Stacked against its listed competitors, the differences are stark. The Apple MacBook Pro M4, ASUS ProArt, and Lenovo Legion are full-powered laptops designed for creative and gaming work. They outperform this HP in every single metric by a colossal margin. A more apt comparison might be against other thin clients or basic Chromebooks, but even there, the mt440 G3's price is high. You're really paying for the HP business brand, the ThinPro OS integration, and the specific durability features, not for raw specs.

Skip this if you need to do any meaningful work directly on the laptop itself. Students, creators, gamers, and anyone who uses demanding software like Adobe Creative Suite, development IDEs, or even moderately complex spreadsheets should look elsewhere. Its CPU, RAM, and storage all rank in the bottom 15% of laptops, making it ill-suited for local processing. You're buying a screen and a keyboard for your cloud PC, not a standalone computer.

We can only recommend the HP mt440 G3 Mobile Thin Client if you are specifically ordered to buy a thin client by your workplace IT policy. Its performance is a real letdown for any local computing, its screen is mediocre, and its price is high for the components. However, as a dedicated, secure, and portable window into a powerful cloud desktop, it does its one job. For literally any other use case—student work, personal computing, content creation—this is an easy pass.
