Should I buy 16 GB of DDR3 or 8 GB of DDR4 memory?

This is a bit of a tough question to answer, if only because these two types of memory offer different benefits and advantages. They aren’t a true “apples to apples” comparison but much more of an “apples to oranges” one.

Yes, the overwhelming majority of “regular” computer user is going to be able to take advantage of the 16 GB of DDR3 memory more so than not – but there are some unique instances where it may be more advantageous to have just 8 GB of DDR4 memory in your computer, depending upon the kind of hardware that you’re running as well as the programs and software that you have taken advantage of the available memory, to begin with.

Brian, an IT Support guy from Auckland (New Zealand), says, “As a general rule, DDR4 is significantly improved in the power savings department, but even there, the advantages aren’t all that noticeable to your everyday average user.” This kind of memory’s latency is higher than DDR3, even though the RAM is clocked at higher speeds.


So there aren’t going to be any immediate performance bumps when it comes to using the 16 GB of DDR3 versus the 8 GB of DDR4 – unless, of course, you’re using pretty resource-hungry programs and applications as well as hardware options that need more base memory.

You see if you’re running multiple applications and pieces of hardware that are drawing more than 8 GB of available memory, your prograwillt paging – and that’s when your speed will willonsiderably.

Your computer will slow down to almost a crawl as it fights for every scrap of available memory, and it will put a lot of pressure on top of your available RAM in a way you probably wouldn’t have expected or anticipated. The 16 GB of DDR3 memory in that specific situation would help make your computer significantly faster, if only because it makes more memory available to your computer and your programs so that this kind of paging doesn’t happen in the first place.

DDR4 memory is the next iteration of RAM and has some benefits over DDR3. But suppose you are using resource-intensive programs and hardware that is heavy on your RAM allocation. In that case, it may be more advantageous to go to the previous generation of DDR3 and get your hands on 16 GB versus half that of the new stuff.
