Modern development workflows — Docker containers, compiling large codebases, test suites, and local development servers — are memory and storage intensive. A RAM upgrade often eliminates the frustrating slowdowns with too many IDE tabs and containers.
Developer Upgrade Priorities
| Upgrade | Use Case | Cost |
|---|---|---|
| RAM: 16GB → 32GB (or 64GB) | Docker, VMs, IDE + browser | ~£65-130 |
| SSD: 512GB → 2TB NVMe | Multiple repos, Docker images | ~£85 |
RAM by Stack
Web development (Node.js/React): 16GB minimum, 32GB recommended. Java/Kotlin (IntelliJ): 32GB strongly recommended — the IDE alone uses 4-8GB. Data science (Python/Jupyter): 32-64GB. Mobile development (Android Studio): 32GB minimum for emulator + IDE.
Frequently Asked Questions
Is 16GB enough for programming in 2026?
For web dev with VS Code and a few containers, yes. For Java with IntelliJ or Android Studio, 32GB is the practical minimum.
DDR4 or DDR5 for development?
For a new laptop, DDR5 offers better compilation performance. But don’t replace a DDR4 laptop solely for DDR5.

How we verify this guide
We cross-reference compatibility figures against manufacturer specifications where available, official service manuals, and the standards that govern fit — memory type and speed (DDR4 / DDR5 / LPDDR5), maximum supported capacity and slot count, SSD form factor and interface (M.2 2280, NVMe PCIe vs SATA, keying), and charger wattage and connector (USB-C Power Delivery, GaN). We’re explicit about soldered or non-upgradeable parts, prioritise primary sources over retailer listings, and re-verify the data on a regular cycle. More on our method →
