We take a look at dozens of laptops yearly right here at ZDNET, and our testing course of employs a twin strategy. On one hand, we run a collection of benchmarking packages to collect essential system information and metrics. Alternatively, we strategy laptops the way in which any regular shopper would, contemplating ease of use, type issue, sturdiness, and battery life.
Additionally: The perfect laptops: Skilled examined and reviewed
Our core testing philosophy is straightforward: whereas it is crucial to collect information, numbers aren’t the entire story. Laptops could be very private, and as such, there’s an intuitive, human component that may’t be ignored, and we take that under consideration whereas writing our opinions.
How we take a look at laptops in 2025
You solely get one first impression, and once we get a brand new laptop computer to evaluate, we all the time pay attention to preliminary perceptions earlier than diving into the info. Upon establishing the laptop computer’s working system, connecting to Wi-Fi, and logging in with any related credentials, we pay attention to how clean the startup course of was. Was it fast and painless? Or was there plenty of clicking to get by means of all of the product presents and bloatware? (Home windows 11, I am you.)
We give all of the units we take a look at equal footing by beginning with the latest updates to the system’s working system, in addition to all related drivers for the GPU, BIOS, and {hardware}. It may be straightforward to skip over these updates, however you do not want me to inform you that not updating your pc can lead to some weird conduct.
The core elements of a laptop computer
These are an important core system metrics we take a look at in the course of the testing course of:
-
The processor (CPU): That is the “mind” of the laptop computer, and one of the crucial essential elements that determines efficiency. The 4 largest producers that make many of the CPUs present in laptops at this time are Intel, AMD, Qualcomm, and Apple (in their very own machines solely).
-
RAM: Random entry reminiscence acts as your pc’s short-term reminiscence and is concerned in multitasking as you edit paperwork, run a number of apps, and most significantly — browse the online. The quantity of RAM your pc has is measured in gigabytes (GB) and begins at 8GB, and goes as much as 32GB and past.
-
Storage: Additionally measured in gigabytes (GB) or terabytes (TB), the place one terabyte equals round 1,000 gigabytes. That is the storage financial institution the place your pc’s recordsdata, paperwork, pictures, and movies are saved. Most laptops lately have a minimum of 128GB of storage, the place some go as much as 1, 2, or extra terabytes.
-
The graphics processor (GPU): Whether or not it is built-in into the CPU or a devoted graphics card, how properly the machine handles graphics is a key issue in the case of demanding visible duties like video enhancing, rendering, and naturally, gaming.
-
The show: The dimensions of the show (measured diagonally from nook to nook) can be what dictates the laptop computer’s total dimension, and nearly all the time included within the mannequin’s title. Shows run the gamut, as they typically play a giant function within the laptop computer’s price. On lower-end machines, you will discover decrease brightness (measured in “nits”) and decrease resolutions. Larger-end laptops typically function OLED shows, which are sometimes probably the most visually pleasing, together with excessive refresh charges (120Hz and above).
-
Port choice: Completely different people could have completely different wants in the case of ports. We all the time establish what’s obtainable and the way the port choice aligns with the system’s focused use case.
-
Bodily type issue: Lastly, the laptop computer’s total look and bodily type issue encompasses its weight, thickness, how the keyboard and trackpad really feel, and whether or not or not it has a show that may be folded again to type a pill or touchscreen.
What makes a laptop computer ZDNET Really useful?
Clearly, extra elements go right into a laptop computer’s remaining evaluate aside from being merely “good” or “high-performing.” Sure, function units are finally subjective, however we advocate a laptop computer when it fulfills the next necessities:
- Expectation: At the beginning, does the laptop computer carry out the way it’s meant to? If a laptop computer is marketed to be a gaming machine, how properly does it run high-end video games? If it is a laptop computer designed for creators, does it deal with video and picture enhancing effectively? Understanding what a laptop computer is designed for — and the way properly it executes on that area of interest — goes a protracted strategy to being beneficial.
- Worth: A laptop computer’s worth is extra than simply how good its worth appears to be like. A extra correct strategy to gauge its worth is by contemplating how properly it performs inside its worth level. A $500 laptop computer ought to feel and look like a $500 laptop computer. Very like how a $1,000 laptop computer ought to really feel prefer it’s twice as quick. We give further consideration to laptops that carry out above their worth level.
- Efficiency: There is not any must beat across the bush. When it comes all the way down to it, extremely beneficial laptops carry out. They’re quick, environment friendly, and simple to make use of. Whether or not meaning looking the online with ease on a $300 Chromebook or rendering 4K video tasks in a top-of-the-line MacBook Professional, the size is completely different, however the core concept is identical: excessive efficiency is vital.
- Excellence: A extremely beneficial laptop computer ought to punch above its weight in a number of areas. We wish to spotlight laptops that do not simply meet the bar however exceed it, both in design, battery life, show, efficiency, or worth.
Benchmarking and system information
In an effort to collect detailed details about the laptop computer, we run a number of completely different diagnostics packages that present at-a-glance summaries for its {hardware} and software program. There are fairly a number of packages on the market that may do that: SiSoftware Sandra is one such dependable program, in addition to GPU-Z, which supplies all of the detailed info you can ever need about your pc’s graphics processor.
We then run a collection of benchmarking assessments to place the pc’s {hardware} by means of the wringer in an effort to see what they’re able to. Cinebench is among the mostly used {hardware} testing suites, which assessments the laptop computer’s rendering efficiency on single and a number of CPU cores, after which compares these numbers in opposition to different machines. PCMark 10 is one other highly effective benchmarking suite that covers all kinds of duties carried out within the trendy office.
Additionally: The perfect OLED laptops: Skilled examined and reviewed
Geekbench is one other {industry} normal testing program that gives a numerical rating to your laptop computer’s processor’s efficiency in quite a lot of completely different use case classes. For instance, how properly the CPU handles frequent on a regular basis duties equivalent to file compression, navigation, and looking in its productiveness workload, as properly its developer and machine studying workloads.
Different benchmarking software program purposes we repeatedly use embody 3DMark, which assessments the laptop computer’s graphics efficiency, (notably essential with gaming laptops), and JetStream2, a browser-based benchmarking software we run on Chromebooks.
After finishing quite a lot of metric-oriented testing, we then evaluate the outcomes of the assessments up in opposition to the producers’ claims. Normally, the info is near the marketed numbers, however each now and again we’ll see some outliers that immediate extra investigation or testing, noting this within the system’s remaining evaluate.
Lastly, relying on any area of interest use instances, we will take a look at the laptop computer’s efficiency additional in particular areas. For instance, if a machine is geared towards creators, we’ll run picture and video enhancing software program, whereas testing a gaming laptop computer would not be full with out firing up a handful of video games.
In these situations, we pay shut consideration to the efficiency of the laptop computer’s GPU, how the show handles rendering duties, and efficiency whereas multitasking whereas working choose efficiency testing software program.
How we take a look at laptop computer batteries
Battery life is a type of issues that each one shoppers care about. No matter what sort of system you are utilizing, and whether or not it is $300 or $3,000, in case your laptop computer is useless, it is ineffective.
We strategy testing a unit’s battery in largely the identical approach. Principally, the thought is to let the laptop computer run for so long as it could actually beneath a medium load. First, we guarantee screensavers and hibernation mode are turned off, in addition to any battery-saving efficiency mode (though working assessments in that mode can be invaluable; it is only a separate take a look at).
Additionally: The perfect battery life laptops: Skilled examined and reviewed
We then set the show’s brightness and audio at 50%, flip off any RGB or keyboard backlighting, load up a livestream on YouTube in Chrome, set a timer, and wait ’til the tip. In my expertise, battery life is a type of metrics that has modified loads throughout the previous few years, and it retains getting higher. With new developments with AI-powered chips, battery life has exploded into heights that just some years in the past would have been thought-about nigh unimaginable.
With this in thoughts, placing each laptop computer we evaluate to the take a look at is extra essential than ever, to unravel producers’ typically “formidable” claims.
The human component
As we talked about earlier, metrics and system information is essential, however numbers alone do not provide the full image. That is the place we weave in our private expertise with the system and faucet into the sensible use instances that buyers really care about.
Laptop computer producers all the time have a particular demographic in thoughts once they design a brand new mannequin, so that is the place information of that advertising and marketing facet comes into play. If a pc is designed particularly for video and picture editors, how properly do industry-standard packages like Adobe Photoshop, Premiere Professional, and OBS really run?
Additionally: The perfect light-weight laptops: Skilled examined
For productivity-focused laptops, how lengthy do their batteries final? Can they multitask on three screens in addition to they promote?
In the end, our aim right here is to interrupt down the capabilities of each laptop computer we take a look at into digestible phrases that actual individuals can discover helpful. There’s plenty of noise and confusion in the case of navigating the laptop computer and pc shopper market, so we hope to convey an intuitive component to the entire course of by leveraging our workforce’s a long time of expertise.
