Is 8GB of DDR4 actually better than 16GB of DDR3?
Yes, this is about RAM. Hang in there.
I have 6 gallons of water that I need to transport to the other side of the country
ASAP. I have two options:
An 8 gallon truck that moves at 60 mph, or
A 16 gallon truck that moves at 40 mph.
In this case, the 8 gallon truck is the obvious answer. It’s faster, and gets the job done.
But what if I had 10 gallons of water and the same two options? I’d obviously need the 16
gallon truck.
It’s the same concept with RAM. Generally speaking, running programs need RAM to
reside in, and excess RAM makes no difference. All other things being equal, DDR4 is
always faster than DDR3.
If you’re running no more than 8 GBs worth of programs at any given time, then the 8 GB
DDR4 RAM is the obvious choice, because it’s faster. However, if you’re running more
than 8 GBs worth at a time, then you’ll want the 16 GB DDR3, because 8 GB just isn’t
enough.
EDIT: Lots of people have been pointing this out, so I feel I should specify this.
The performance difference isn’t that great between DDR3 and DDR4. Many programs
have many ways they can take advantage of extra RAM. What I’ve said is still true, but
the 16 GB DDR3 will be more beneficial in most cases, and my answer seems to imply the
opposite.
