DDR4 efficiency?

Jobinx · February 4, 2017

I did a couple of tests.

With GTA 5, Spotify, Discord, Steam, and a bunch of Chrome tabs (one was playing a 4k video), I reached a peak of 9.2 GB of RAM used. (Currently have 4 sticks, 12 GB, DDR3, 1333 MHz)

How efficient is DDR4 vs. DDR3 in terms of RAM usage?

Would 8GB of DDR4 (2133 MHz) be enough memory, or should I get 16GB?

There's no usage difference that will be noticeable.

Well, RAM is memory, memory is measured in bits, so 12GiB of DDR3 will be 12884901888 Bits,
And conversally, 12GiB of DDR4 will be 12884901888 Bits,

Now I know there might be a slight reduction, it won't be due to DDR3/DDR4 differences, more than likely due to most of the IMC and processors being better.

8 is probably not enough especially if you hord Chrome tabs and play games at the same time. 16 should be plenty for what you mentioned though. There really isn't a difference in how much is used from DDR3 to DDR4 though, it's what you have running and a little to do with how good your CPU is but mostly just what you have running.
