How significant is the speed improvement of DDR4 compared to DDR3 RAM?

Unless you look at fringe things like 0.1% percentile frame time, there is little difference between the same amount of 1600MT/s DDR3 and 2400MT/s DDR4 with similar latency for gaming. For general productivity where the human is the primary bottleneck, it will make no meaningful difference.

Can't be looked at in isolation.
To move to DDR4, you need a new motherboard and CPU. So that changes the whole thing.

On the very few boards that can use either DDR3 or DDR4....you'd see a teeny increase, if anything.


Now...why are you asking? What are you looking to do?

The overall speed of RAM isn't advancing at a great pace (considering the larger CS latency that tends to accompany the higher frequencies of newer RAM generations). On the other hand, RAM itself is only one component out of many. As the industry adopts new standards any new system built to use m.2 or PCIe SSD, newer generations of PCIe tech and cards, etc will require DDR4.

As a general matter, the overall focus on when it's worthwhile to upgrade generally won't hinge on RAM anymore. Of course the CPU is always the single most important component (albeit we're in a lull in CPU development on the desktop, where only mobile chips are racing to catch up).

I am using my PC for gaming, from AAA titles to less demanding titles. Also, I plan on writing large amounts of text on google drive and MS Word
