How to choose a laptop: processors, graphics, RAM, storage and screens

Laptop specification sheets are long, and most of the words on them, such as Core Ultra 7, Ryzen 5, RTX, LPDDR5X and 120 Hz, mean little unless you know what you will use the machine for. The good news is that a few decisions matter far more than the rest: how much memory it has, how much storage, how good the screen is, and whether you need dedicated graphics. This guide explains each in plain terms so you can buy the right machine without paying for power you won't use.

Start with what you'll do

Most people fall into one of three groups:

Everyday use: web, email, documents, streaming, video calls. Almost any current mid-range processor is plenty; spend on the screen, battery and build.
Heavier work: large spreadsheets, photo editing, programming, many browser tabs, some video editing. More memory and a stronger processor pay off.
Gaming, 3D and serious video work: a dedicated graphics chip, good cooling, more memory and a faster screen.

Processor tiers in plain terms

The main processor families use similar tier numbers:

Family	Tiers	Notes
Intel Core / Core Ultra	3, 5, 7, 9	Older models used names such as Core i5 and i7
AMD Ryzen / Ryzen AI	3, 5, 7, 9	Model numbers indicate generation and class
Apple M-series	Base, Pro, Max	Only in Apple laptops, running macOS
Qualcomm Snapdragon X	Several tiers	Arm-based chips running Windows on Arm

As a rough guide, tier 3 suits light use, tier 5 is the sweet spot for most people, tier 7 suits heavier work, and tier 9 is for demanding creative and gaming machines.

Three things complicate the tiers:

Generation matters as much as tier. A recent tier-5 chip can outperform an older tier-7 one. Compare the generation, not just the badge.
Suffixes and power. Letters after the model number signal the power class. Low-power chips (often marked U, or unlabelled in thin models) favour battery life and quiet running; high-power chips (often H or HX) are faster but need more cooling and battery.
Cooling. The same processor can perform very differently in a thin laptop and a thick one, because thin designs limit the power it can use for long periods.

Windows on Arm laptops can offer excellent battery life. Most software runs, many apps natively and others through built-in emulation, but check that any specialist software, drivers, printers or games you depend on are supported.

Many recent processors include an NPU (neural processing unit) for on-device AI features. It matters if you want specific features that require one, such as those tied to Microsoft's Copilot+ PC label; otherwise it is not yet a deciding factor for most buyers.

Integrated or dedicated graphics

Integrated graphics are built into the processor and share the main memory. Modern integrated graphics handle everyday work, video playback, multiple monitors, photo editing and many lighter or older games.
Dedicated graphics (a separate GPU with its own video memory) are needed for demanding games, 3D work and faster video and AI workloads.

Dedicated graphics add weight, heat, fan noise and cost, and shorten battery life. When comparing gaming laptops, note that the same graphics chip can be set to run at very different power limits in different laptops, which changes performance a lot. Look for the maximum graphics power in the specifications, and the amount of video memory.

How much RAM

RAM holds the programs and files you are actively using. Running short makes a laptop slow, especially with many browser tabs.

8 GB: the bare minimum for light use; it fills quickly with modern browsers and apps.
16 GB: the sensible choice for most people, and good for years.
32 GB or more: heavy video and photo editing, large software projects, virtual machines and demanding games.

Many thin laptops have soldered memory that cannot be upgraded later, so buy what you'll need for the laptop's whole life.

Storage: size and type

Nearly every laptop now uses a fast NVMe SSD, which is what makes it boot and open apps quickly.

256 GB fills up fast once the operating system, updates and a few apps are installed.
512 GB is a comfortable minimum for most people.
1 TB or more suits photo and video libraries and large games.

Check whether the laptop has a spare SSD slot or a replaceable drive. Avoid machines with very slow eMMC storage except for the lightest tasks. For backups and extra space, our external storage guide explains the options.

The screen

You look at it every minute you use the laptop, so it is worth prioritising.

Size: 13–14 inches for portability, 15–16 inches for more working space, 17–18 inches mainly for desktop replacements.
Aspect ratio: taller 16:10 or 3:2 screens show more of a document than 16:9.
Resolution: sharper screens make text crisper. Full HD is fine on a 14-inch screen; higher resolutions look sharper but use more power.
Brightness: around 300 nits is fine indoors; 400–500 nits or more helps near windows or outdoors.
Colour: for photo work, look for close to full sRGB coverage, or DCI-P3 for wider colour.
Panel type: OLED offers deep blacks and vivid colour; IPS-type LCDs are common and consistent. Matte finishes reduce reflections.
Refresh rate: 90–120 Hz makes scrolling smoother; gamers may want higher.

Battery life and charging

Battery capacity is measured in watt-hours (Wh). Manufacturer battery claims come from light tests, often video playback at low brightness, so real mixed use is usually lower. Efficient processors and screens matter as much as capacity.

USB-C charging is now common, so one charger can often power your laptop and phone. Check the wattage your laptop needs; our guide to USB-C chargers and GaN explains how charging power is negotiated.

Ports, keyboard and the rest

Ports: USB-C with Thunderbolt or USB4 supports fast storage and docks; HDMI and USB-A avoid adapters; an SD card reader helps photographers.
External monitors: check how many the laptop can drive. Our monitors guide covers single-cable docking.
Keyboard and trackpad: comfort matters for long typing sessions; check the layout for your language.
Webcam and microphones: a 1080p camera helps video calls.
Weight: under about 1.4 kg feels easy to carry daily.
Operating system: Windows, macOS and ChromeOS all suit different needs; check your key apps run on the one you choose.
Wi-Fi: current Wi-Fi standards help if your router supports them; see our mesh Wi-Fi guide.

For reading, streaming and light tasks on the sofa, a large tablet may be an alternative.

The short version

Choose a recent tier-5 processor for most uses; tier 7 or higher for heavy work.
16 GB RAM and 512 GB SSD are the sensible starting points; check whether memory is soldered.
Only pay for dedicated graphics if you game or do 3D or heavy video work.
Prioritise a bright, sharp 16:10 screen you'll enjoy looking at.
Treat battery claims as best-case; check USB-C charging and ports.
