16 GB is no longer comfortable, 32 GB is the sensible default, and 64 GB is a workload decision rather than a future-proofing one.
The honest answer is that most people buy either too little or far too much, and the two mistakes cost very different amounts. Buying short means swapping to disk during ordinary work. Buying long means paying for capacity that sits idle for the life of the machine.
16 GB still runs everything. It stopped being comfortable somewhere around 2023, when browsers, chat clients and background updaters collectively started assuming they could hold a gigabyte each without anyone noticing.
It remains the right choice in exactly two situations: a machine with a fixed budget where the money is better spent on storage or a GPU, and a laptop whose memory is soldered and whose owner genuinely only browses and writes documents.
For a desktop built in 2026, 32 GB is the capacity that stops you thinking about memory. It absorbs a game, a browser with sixty tabs, a chat app and a recording tool at once. It is enough for a virtual machine alongside normal work. It is roughly where the price-per-gigabyte curve bottoms out, because 2×16 GB kits are the highest-volume configuration on the market.
Two modules, not four. A two-module kit runs at its rated speed far more reliably than four modules on the same board, and it leaves slots free.
Above 32 GB, capacity should answer a specific question. Video editing at 4K with multiple streams, running local language models, compiling large codebases, or hosting several virtual machines are all real reasons. "Future-proofing" is not one — memory gets cheaper and faster, and buying two generations ahead means paying today's price for tomorrow's midrange.
Capacity is the first decision; speed is the second, and it is more constrained than the marketing suggests.
On AM5, the sweet spot is DDR5-6000 with a CL30 timing, because that is where the memory controller runs synchronously with the fabric. Faster kits often run slower in practice once the controller drops to a divided ratio.
On current Intel desktop platforms the tolerance is wider, and DDR5-6400 and above remain useful.
G.Skill Flare X5 DDR5-6000 CL30 2x16GB| Use | Capacity | Notes |
|---|---|---|
| Office, browsing | 16 GB | 2×8 GB |
| Gaming, general desktop | 32 GB | 2×16 GB — the default |
| Content creation | 64 GB | 2×32 GB, keeps slots free |
| Local LLMs, many VMs | 96–128 GB | Check the board's validated list first |
For why the CL numbers on those kits do not compare across generations, see DDR4 vs DDR5, explained.
Capacity avoids stutter caused by running out of memory; speed affects how efficiently the CPU feeds data to the GPU. They solve different problems, and buying enough of the first one before spending on the second is the right order.
Whether a laptop can be upgraded at all depends entirely on which of three physical memory formats it uses, and that has to be confirmed before comparing a single spec sheet.
On a fixed budget, RAM is one of the few components where the cheap, sensible choice and the expensive, marginal upgrade are easy to tell apart -- which makes it a good place to save, not a good place to cut.
