UCALCUL 15.6 inch Laptop, Laptops with Celeron N4000, 2025 Review

The UCALCUL 15.6 inch laptop is a $210 machine, and that price tag tells you most of what you need to know. It's built around an Intel Celeron N4000, a dual-core CPU from several generations ago, paired with 8GB of RAM and a 256GB drive. In our overall scoring, it lands at an 8.5 out of 100, which puts it squarely in the budget basement. Its best score is a 13.1 for 'compact' use, but that's not saying much when its weakest area, gaming, scores a dismal 2.6.

Looking at the percentile rankings, this laptop doesn't have a single standout feature. Its best relative performance is for compactness, sitting in the 46th percentile. Everything else falls below average, with CPU performance at the 35th percentile and GPU performance scraping the bottom at the 18th. The most concerning number is reliability, which sits in the 3rd percentile. That's a red flag you can't ignore.

Performance is exactly what you'd expect from a Celeron N4000 and integrated graphics. The CPU lands in the 35th percentile, meaning about two-thirds of the laptops we track are faster. For basic web browsing and document editing, it'll get the job done, but open more than a few tabs and you'll feel it start to chug. The GPU is even weaker, in the 18th percentile, so forget about any modern gaming or video editing. Even playing HD video might cause some stutter.

The 8GB of RAM is in the 10th percentile, which is a major bottleneck. Windows 11 will use a big chunk of that just idling, leaving very little headroom for your actual applications. The 256GB storage drive is also in the 12th percentile, so you'll be managing your files carefully. This isn't a performance laptop; it's a 'get the absolute basics done' laptop.

At $210, the value proposition is purely about the entry price. You are getting a functional Windows computer for the cost of a high-end smartphone accessory. However, the value per dollar for actual performance is poor. You're paying for components that were low-end five years ago. The abysmal reliability percentile (3rd) means you're taking a significant gamble. This laptop might save you money upfront, but it could cost you more in frustration and potential repairs down the line. It's the definition of 'you get what you pay for,' and in this case, you're not getting much.

Comparing this to its listed 'competitors' is almost laughable—they're in a completely different universe. The Apple MacBook Pro M4 or Lenovo Legion Pro 7i are performance powerhouses that cost ten times as much. A more realistic comparison would be against other budget Chromebooks or used business laptops. For a similar $200-$300, you could find a used Dell Latitude or Lenovo ThinkPad from a few years ago with an 8th-gen Core i5, 16GB of RAM, and a 512GB SSD. Those would demolish this UCALCUL in CPU performance (likely 70th+ percentile), have double the RAM, and come from lines known for much higher reliability. The only thing this UCALCUL has over a used business laptop is that it's new.

I can only recommend the UCALCUL 15.6 inch laptop in one very specific scenario: you need the absolute cheapest possible new Windows machine for a single, simple task (like running a point-of-sale system or a kiosk), and you're willing to accept a high risk of it failing early. For anyone else—students, home users, small business owners—this is a bad buy. The terrible reliability score, weak specs across the board, and low performance percentiles make it a liability. Save up another $100-$150 and buy a used business laptop or a better-specced entry-level model. Your future self will thank you.
