To answer these questions we performed some testing, looking at specific use cases, identifying the basic memory requirements for each and providing some hard numbers to back our advice. While opting for more RAM is always good advice, it doesn’t answer the more specific questions of how much RAM is needed for specific uses, or what you can reasonably expect to do with the RAM your laptop already has. The answer to the question of how much RAM you need will always come back to what you want to do with your laptop. Too little RAM creates a bottleneck that slows everything down, and the basic rule of thumb is that more RAM is always better. While your overall performance will largely be dictated by the capabilities of your processor and graphics hardware, your memory allotment will directly impact how well you can take advantage of that performance. The bottom line is that RAM is essential to the smooth operating of your computer, particularly for things like multitasking and accessing multiple files at one time.


A swap file still lets you get some things done, but will be dramatically slower. It will try to use this swap file in the same way it does RAM, constantly reading and writing the data during operation, but the memory in your storage drives simply isn’t designed to move data as rapidly as DRAM. Once you hit the limit of what your RAM can hold, then your computer will compensate with a swap file, putting some of the data onto your storage drive.
