RAM is one of those specs that appears on every laptop and PC listing, but rarely comes with a straight explanation of what it actually means for you. Too little and your machine feels sluggish. Too much and you’ve spent money you didn’t need to. Here’s what you need to know.
What RAM actually does
RAM (Random Access Memory) is your computer’s short-term workspace. It holds everything currently running — open browser tabs, documents, apps, and the operating system itself. The more RAM you have, the more your computer can juggle at once without slowing down.
It’s different from storage (your SSD or hard drive), which holds files permanently. RAM is temporary: everything in it disappears when you shut down. Think of storage as your filing cabinet and RAM as your desk. A bigger desk lets you have more things out at once.
Why it matters: When you run out of RAM, your computer starts using part of your storage drive as overflow. This is dramatically slower and is exactly why low-RAM machines feel like they’re wading through treacle when you have multiple apps open.
Is 8GB RAM enough?
8GB — Fine, but tight
8GB will handle email, web browsing, word processing, video calls and streaming without much trouble — as long as you don’t do too many things at once. The problem is that Windows 11 itself uses 3–4GB at idle, which doesn’t leave a lot of headroom.
Where 8GB struggles is multitasking. If you regularly have 15+ browser tabs open alongside a video call and a spreadsheet, you’ll notice lag. Chrome and Edge are particularly RAM-hungry — each tab consumes memory, and modern websites are significantly heavier than they used to be.
For a budget laptop used lightly by one person, 8GB is acceptable. For anything more demanding, 16GB is worth the modest extra cost.
When 16GB is the right choice
16GB — Right for most people
16GB is the sweet spot for 2026. It handles general work, casual gaming, light creative tasks and real multitasking comfortably. You can run a full browser, a Teams or Zoom call, a spreadsheet and a document editor simultaneously without hitting the ceiling.
If you’re buying a new laptop or desktop today and you’re unsure, default to 16GB. It’s the option you’re least likely to regret. The price difference between an 8GB and 16GB configuration is typically £50–£100 at purchase — substantially less than the cost of upgrading or replacing later.
Who actually needs 32GB or more
32GB+ — For specific workloads
32GB is overkill for the vast majority of users. It genuinely earns its place for video editing in Premiere or DaVinci Resolve, 3D rendering, running multiple virtual machines, large-scale data work, or professional photo editing with very large RAW files.
64GB and above is for specialist workstations — scientific computing, server workloads, or professional broadcast production. If you’re asking whether you need it, you almost certainly don’t.
Quick verdict
8GB: Basic use only — will feel tight within a year or two. 16GB: Right for almost everyone — work, study, gaming, general use. 32GB: Only if you edit video, run virtual machines, or work with large datasets professionally.
How to check how much RAM you have
Before upgrading or buying, it’s worth knowing your starting point.
- Windows: Press Ctrl + Shift + Esc to open Task Manager → Performance tab → Memory. You’ll see total RAM, how much is in use, and your memory speed.
- Mac: Apple menu → About This Mac → Memory. On Apple Silicon Macs (M1 onwards), this shows “unified memory” which functions differently but serves the same purpose.
- What to look for: If your RAM usage regularly sits above 80% during normal use, you’d benefit from an upgrade or a device with more memory.
Should you upgrade your RAM or buy new?
This depends entirely on your device. Many modern thin laptops — particularly Apple MacBooks and ultrabooks — have RAM soldered directly to the motherboard, meaning it cannot be upgraded after purchase. If your laptop is in this category, your only option is a new machine with more memory.
Older laptops, most desktops, and many business-grade machines typically have upgradeable RAM slots. A RAM upgrade is usually one of the most cost-effective performance improvements you can make — often £30–£80 for a meaningful boost.

Common questions about RAM
8GB is workable for basic tasks — email, light browsing, video calls and streaming. It struggles with real multitasking because Windows 11 itself uses 3–4GB at idle, leaving limited headroom. Most people buying in 2026 should target at least 16GB.
16GB handles proper multitasking — a browser with 20+ tabs, a video call, a document and a spreadsheet running simultaneously without slowdown. 8GB will stall under that kind of workload. The practical difference is very noticeable day to day.
Almost certainly not, unless you edit video professionally, run virtual machines, work in 3D rendering, or process large datasets. For general work, gaming or working from home, 16GB is more than sufficient and 32GB is wasted spend.
It depends. Many modern thin laptops have RAM soldered to the motherboard and cannot be upgraded. Older laptops and most desktops typically have upgradeable slots. Check your model’s spec sheet or use Crucial’s System Advisor to confirm before purchasing anything.
Windows 11 requires 4GB minimum, but Microsoft recommends 8GB. In practice the OS uses 3–4GB at idle, so 8GB leaves limited room for applications. 16GB is the comfortable practical minimum for a smooth everyday experience.
