At CNET, we test all kinds of laptops — from budget models for everyday tasks to high-performance laptops for gaming and content creation and everything in between. Each member of our team has decades of experience testing and reviewing laptops. We conduct performance testing under controlled conditions in the CNET Labs and extensive hands-on use. This helps us find not only the best laptop overall but also the best laptop for your needs and in your price range.

The review process for laptops consists of two parts: performance testing under controlled conditions in the CNET Labs and extensive hands-on use by our reviewers. This includes evaluating a device’s aesthetics, ergonomics and features with respect to price. A final review verdict is a combination of both objective and subjective judgments. 

We test all laptops with a core set of benchmarks, including Primate Labs Geekbench 5 and 6, Cinebench R23, PCMark 10, a variety of 3DMark benchmarks (whichever can run on the laptop), UL Procyon Photo and Video (where supported), and our own battery life test. If a laptop is intended for gaming, we’ll also run benchmarks from Guardians of the Galaxy, The Rift Breaker (CPU and GPU) and Shadow of the Tomb Raider.m/laptop
