HP 250 G9 review - An affordable office laptop with a Core i3 and an IPS panel

HP 250 G9 review - An affordable office laptop with a Core i3 and an IPS panel

With the 250 G9, HP is offering a reasonably-priced 15.6-inch office laptop equipped with an Intel Core i3 processor and a matte IPS display - all of which can be had for around $390. The device's performance is sufficient for basic tasks but the fan quickly gets annoying.

Lenovo ThinkBook 16 G6 review - The inexpensive multimedia laptop with a Ryzen 7000

The Lenovo ThinkBook 16 G6 is a 16-inch multimedia laptop with an IPS display and an AMD Ryzen 7000 processor. At a price of US$900, you will surely have to make quite a few compromises but even so, it boasts a good keyboard and long runtimes.

Acer Predator Helios Neo 16 gaming laptop — Notebookcheck review

Predator Helios Neo 16 laptop review: Acer has created a gaming chimera

The gaming laptop Predator Helios Neo 16 from Acer is supposedly a cheaper alternative to the regular Helios 16, while still offering a variety of mid-range features, such as an extremely robust and sleek case, lots of connectivity options, a desktop-class CPU, as well as a powerful cooling system which makes use of liquid metal. In this review, you can find out whether this concept is a success.

Acer Swift Edge 16 Ryzen 7 7840U laptop review: Zen 4 CPU and 3.2K 120 Hz OLED boost

The Acer Swift Edge 16 is one of the lightest 16-inch laptops in the market right now with the new Ryzen 7 7840U. There's no doubt that its CPU and 120 Hz OLED display are both impressive, but weaknesses elsewhere on the model shouldn't be ignored.

Acer Nitro 16 AN16-41 Review: Affordable gaming laptop with RTX 4050 and long run times

A Ryzen 5 7535HS, GeForce RTX 4050, USB 4, and a bright 16:10 display (16-inch, WUXGA, 165 Hz, G-Sync) are the highlights of the relatively inexpensive (€1,250) Nitro 16. Under the right conditions, the already very good battery run times of the predecessor further surpassed. This review evaluates the performance and other characteristics of this alternate configuration.
