Introduction
Many of you who monitor recent technological innovations have probably heard of an emerging technology, known as DDR4. While standard DDR3 Memory inhabits the majority of our laptops and desktops purchased in the last 4 to 5 years, DDR4 memory will overthrow it in terms of speed and size.
MT/s: comparison
A feature that makes DDR4 memory more desirable than DDR3 memory is its ability to achieve higher Mega transactions a second (MT/s), or the sticks ability to write or read however many binary integers in a second. There is a distinct difference in price when purchasing 16 GB of high-speed ddr4 memory vs high speed ddr3 memory. Two examples below, first result off amazon for given queries.

By using ddr4 memory, you can drastically save money when using high-speed memory.
CAS Latency
When comparing RAM modules, CAS latency (abbreviated as CL) is an important aspect to look into. A disadvantage DDR4 has against DDR3 is it has higher latencies. For those of you who don’t know what this means,
Column Address Strobe (CAS) latency, or CL, is the delay time between the moment a memory controller tells the memory module to access a particular memory column on a RAM module, and the moment the data from the given array location is available on the module's output pins. In general, the lower the CL, the better. [Wikipedia].
While ddr3-2133 ram may have a CL of, say, 9 or 10, ddr4-2133 will have a CL of 15 or higher. While it is debated that the difference is negligible, the CAS latency can still be important for video editors or power users.
Power requirements
An advantage ddr4 has over ddr3 is that ddr4 uses a bit less power than ddr3. While typical ddr3 DIMMS use 1.5 volts, ddr4 DIMMS use 1.2 Volts, saving electricity while outputting higher performance.
Density
If I had to pick an aspect of DDR4 that is my favorite, storage density would be my choice. A single stick of ddr3 memory can hold up to 8 GB. A single DIMM of DDR4 can hold up to 16 GB. If we do the math, there are new x99 motherboards with 8 slots, 8x16=128. That means, hypothetically, one could install 128 GB of ddr4 memory if he had the stupidity, time and money to do so. However, as the technology matures, we may see instances in the future where having 128 GB of RAM may be beneficial, be it for workstations or multi-user systems. Whatever the cause, the new 16 GB Modules will be beneficial sometime in the future.
Conclusion
In this guide, we have covered a few key aspects of DDR4 memory. While the technology isn’t perfect (yet), it will improve the performance of computers in years to come. Should you get a ddr4 compatible motherboard? I would. Future breakthroughs will allow for even better performance from your system. I hope you found this guide helpful, post anything below if you feel like I should add something .
