How Much Memory Does a Laptop Need? A Plain Answer
16 GB suits most people, 32 GB suits developers and editors, 64 GB is for video and local AI models. Why a pair beats one module, and when to upgrade later.
In short: 16 GB in two modules is enough for browsing, office work and light coding. Choose 32 GB if you run virtual machines, containers or photo editing, and 64 GB for video editing, large datasets or local AI models. On a modular laptop you can start lower and add more later.
Memory (RAM) is where your laptop keeps everything it is working on right now: every open tab, every running app, the operating system itself. Too little and the machine starts shuffling data to the drive, which feels like stutter and spinning cursors. Too much costs money you could have spent on a better screen. Here is how to pick.
The short version
| How you use it | Memory to choose |
|---|---|
| Browsing, email, documents, video calls | 16 GB |
| Programming, many tabs, light photo editing | 16 to 32 GB |
| Virtual machines, containers, Lightroom, large spreadsheets | 32 GB |
| Video editing, 3D, local AI models, big datasets | 64 GB |
8 GB still boots and runs a browser, but a current operating system plus a few heavy web apps fills it quickly. We sell an 8 GB module for people with a specific, light use in mind; for most buyers it is a false saving.
Why two modules beat one
Laptop memory runs in channels. With one module the processor reads from one channel; with a matched pair it reads from two at once, which roughly doubles memory bandwidth. You feel it most in anything that uses the built-in graphics, because those graphics share system memory instead of having their own. So 16 GB as two 8 GB modules is faster than one 16 GB module, and the builder warns you if you pick a single module.
Built-in graphics change the maths
The Ryzen and Core Ultra mainboards in the builder use graphics built into the processor. Those graphics borrow part of your system memory, often a few gigabytes. If you plan to edit photos, play older games or use GPU acceleration on a board without a graphics module, add one memory step above what the table suggests.
DDR4 or DDR5?
You do not choose this directly: the mainboard decides it. Our previous-generation Core i5 board takes DDR4, and every other board takes DDR5. The builder only shows memory that matches the board you chose, so this is one thing you cannot get wrong.
Start small, add later
On a sealed laptop, memory is often soldered, so the amount you buy is the amount you keep. Here the modules sit in standard slots, so you can:
- Buy 16 GB now and swap to 32 GB when your work changes.
- Move the memory to a new mainboard, as long as the memory type matches.
- Replace a faulty module on its own instead of the whole board.
If you go this way, buy the larger kit as a matched pair later rather than adding one odd module to an existing one.
What the presets use
- The Light 13 preset has 16 GB in two modules, which is right for travel and school.
- The Everyday 14 preset has 32 GB, the comfortable amount for development and heavy multitasking.
- The Creator 16 preset has 64 GB alongside a graphics module, for rendering and editing.
Memory is one step of several. The parts guide covers storage, screens and chargers in the same plain way.
