RAM is the one specification where you can genuinely feel the difference — and also the one where buyers most often overpay for capacity they will never use.
Here is the honest position: 8GB is enough for most people in Rwanda in 2026. But the group for whom 16GB is transformative is larger than it was three years ago, and if you are in it, no other upgrade comes close.
This guide helps you decide which side of that line you are on.
What RAM Actually Does
RAM is your laptop's working desk. Every open application — each browser tab, your spreadsheet, the video call, the PDF viewer, the antivirus running quietly in the background — occupies space on that desk while it runs.
When the desk fills up, Windows starts moving things to your SSD to make room. That process is called paging, and it is roughly a hundred times slower than RAM. It is what people mean when they say a laptop "suddenly got slow" after a few months.
The critical distinction: more RAM does not make any single task faster. It determines how many things you can run at once before everything slows down. A processor upgrade makes tasks faster. A RAM upgrade makes your laptop stop stuttering.
What 8GB Really Handles in 2026
Let us be concrete rather than vague. On a Windows 11 machine with 8GB, Windows itself uses roughly 3–4GB before you open anything. That leaves about 4–5GB of working space.
Comfortable on 8GB:
- 10–15 browser tabs
- Microsoft Word, Excel and PowerPoint together
- A Teams, Zoom or Google Meet call — including with background blur
- Accounting software such as QuickBooks or Sage
- Light photo editing
- A code editor with a small to medium project
- Streaming music while you work
That covers the daily reality of most students, office workers, accountants and managers in Rwanda. If your day is described above, 8GB is genuinely sufficient and 16GB is money you do not need to spend.
Where 8GB starts to break down:
- 25+ browser tabs, especially with Google Docs, Figma or web applications open
- A large Excel model recalculating while other applications run
- Docker, virtual machines, or a local database server
- Photoshop or Illustrator with large files
- Any video editing beyond simple trimming
- Android Studio, or a full IDE with a large codebase indexed
What 16GB Changes
With 16GB, Windows takes its 3–4GB and you still have 12GB of working space. In practice this means:
You stop thinking about it. The most accurate description of 16GB from users who upgrade is not "it is faster" — it is "I stopped closing tabs." The mental overhead of managing what is open disappears.
Heavy applications stop fighting each other. Running an IDE, a local server, Docker and a browser simultaneously is routine on 16GB and painful on 8GB.
The machine ages better. Applications get heavier every year. A 16GB machine bought in 2026 will still feel comfortable in 2031; an 8GB machine will feel tight by 2029.
The Head-to-Head: Same Laptop, Both Configurations
We stock the HP EliteBook 840 G7 in both configurations, which makes this an unusually clean comparison.
HP EliteBook 840 G7 — Core i5, 8GB RAM
Price: RWF 465,000
A 10th-generation Core i5 with 8GB of RAM and SSD storage. The right choice for ordinary professional and academic work, and we hold it in quantity.
Available on PrimeTech
HP EliteBook 840 G7 Business Laptop | Intel Core i5 10th Gen | 8GB RAM | SSD
HP EliteBook 840 G7 — Core i7, 16GB RAM, 512GB SSD
Price: RWF 535,000
Same chassis, same generation, same build. Double the RAM, double the storage, and a step up to the i7.
Available on PrimeTech
HP EliteBook 840 G7 Business Laptop | Intel Core i7 10th Gen | 16GB RAM | 512GB SSD
The difference: RWF 70,000.
For that money you get 8GB more RAM, 256GB more storage, and a faster processor. Judged purely on specification-per-franc, it is the best-value machine in our catalogue. Judged on what you actually need, it depends entirely on the list below.
Which One Are You?
Buy 8GB if you:
- Write documents, manage spreadsheets, send email
- Attend online classes or run video calls
- Use accounting or business management software
- Browse with a normal number of tabs
- Do light photo editing or design
- Are a student on a non-technical course
- Want to spend the savings on a docking station, monitor or a good headset
Buy 16GB if you:
- Write software professionally, or run Docker, VMs or local databases
- Edit video, even occasionally
- Work in Photoshop, Illustrator, InDesign or Figma with large files
- Build large financial models in Excel
- Run statistical analysis in R, Python, SPSS or Stata
- Work in CAD, GIS, or architectural software
- Habitually keep 25+ tabs open and refuse to change
- Intend to keep this laptop for six years or more

Can You Upgrade RAM Later?
Often yes — and this is worth knowing before you buy.
Most HP EliteBook and ProBook models have one soldered RAM module and one accessible slot, meaning a machine sold as 8GB can frequently be taken to 16GB by adding a module. Some models have two accessible slots; a few have everything soldered and cannot be upgraded at all.
This varies by exact model and configuration, so do not assume it. Ask us before you buy — contact us with the model you are considering and we will tell you whether that specific unit can be upgraded, and what it would cost.
If a machine is upgradeable, buying 8GB now and adding 8GB when you actually need it is a perfectly sensible strategy — and usually cheaper than buying 16GB up front.
Do Not Confuse RAM With Storage
A surprisingly common mix-up, and an expensive one:
RAM is temporary working memory. It empties every time you shut down. 8GB or 16GB.
Storage (SSD) is where your files and programs permanently live. 256GB or 512GB.
Buying a 512GB SSD will not fix a laptop that stutters with many tabs open — that is a RAM problem. Buying 16GB of RAM will not fix a full drive. They solve completely different problems. Here is the storage question.
