Short answer
Processor, memory, storage type and screen are what matter. For ordinary use, 16GB of memory and an SSD matter far more than a faster processor — and almost every spec sheet leads with the processor.
Specification sheets are written to make comparison difficult. In practice four things determine how a laptop feels to use, and knowing which they are makes the decision straightforward.
Step by step
- Start with memory — it matters most for ordinary use.8GB is a workable minimum, 16GB is comfortable and is what most people should buy. It determines how many things you can have open before the machine slows, and on many laptops it cannot be upgraded later.
- Insist on an SSD, and check the size.Any modern laptop should have one. 256GB is tight, 512GB is comfortable. A mechanical hard drive in a new laptop is a reason to look elsewhere.
- Treat the processor as a tier, not a number.Manufacturers' naming is deliberately confusing. Broadly: entry-level for browsing and documents, mid-range for everything most people do, high-end only for video editing, 3D or heavy development.
- Look at the screen properly.You look at it for hours. Resolution, brightness in nits and panel type matter. A dim, low-resolution screen makes an otherwise good laptop unpleasant, and it is where cheap machines cut cost.
- Ignore graphics unless you need them.A dedicated graphics card matters for gaming, video editing and 3D work. For everything else it adds cost, weight and heat and reduces battery life.
- Check the ports before buying.How many, what type, and whether it charges over USB-C. Discovering you need three adapters is a common and avoidable annoyance.
- Treat battery claims sceptically.Manufacturer figures are measured under undemanding conditions. Independent reviews give a much more realistic number.
- Check the build and the keyboard.Not on the spec sheet and highly consequential. If you can, type on it before buying — a poor keyboard ruins an otherwise good machine.
Tips
- For most people the ranking is memory, storage, screen, then processor. Spec sheets present that order almost exactly backwards.
- Check whether memory and storage are soldered. If they are, buying more at purchase is the only chance you get.
- Last year's mid-range model is usually better value than this year's entry-level one at the same price.
Questions people ask
How much RAM do I need in a laptop?
8GB is a workable minimum and 16GB is what most people should buy. It matters more than processor speed for everyday responsiveness, and often cannot be upgraded later.
Does the processor matter most?
Rarely, for ordinary use. Memory, an SSD and a good screen affect how a laptop feels far more than moving up a processor tier.
