Do you know what is the difference between  DDR 3 and DDR 4 laptop ram? In this post, we will tell you about the DDR 3 laptop ram and DDR 4 laptop ram and the difference between them. Read out the article ahead.

What is DDR 3 RAM?

DDR3 RAM stands for Double data rate third generation. It is a type of memory that is designed to perform better work in a laptop and has extra features than DDR2 RAM.

DDR3 RAM's key features are specifications -:

·        It has a Density of 1 GB to 32 GB.

·        It has Chipkill support.

·        DDR3 RAM Fly-by command/address/control bus with on-DIMM termination.

·        DDR3 RAM has Higher bandwidth performance up to 1866 MT/s.

·        It has a better data transfer speed.

·         Its Better performance at normal and low power voltage is 1.5V (Normal) and 1.35V (Low Voltage).

·        It consumes less power than the previous versions of DDRAM.

·        The latest modules of DDR3 RAM are supported by the Intel Core™ i7 Series, the AMD AM3 Phenom processor series.

 What is DDR 4 RAM?

DDR4 RAM stands for Double data rate fourth generation. It is a type of memory that is specially designed to be a better, faster, more reliable replacement for DDR3 in the laptop.      

DDR4 RAM's key features are specifications -:

·        The density of the DDR4 RAM is 2 GB to 128 GB.

·        It has performance and bandwidth of up to 3200 MT/s for better data transfer at the fastest rate.

·        It has Decreased voltage for better power consumption at 1.2 V for better power saving and higher productivity.

·        It Provides better (RAS) reliability, availability and serviceability as well as improves the data integrity of the laptop.

·        DDR4  is one of the most used latest generation RAM installed in newer versions of laptops for fast performance as compared to all DRAM-oriented modules.

·        The latest version of  Intel Xeon Platinum, Gold, Silver and Bronze Scalable range processors and 8th-generation Intel Core i7/i5/i3 processors support DDR4 RAM.

Difference between DDR 3 and DDR4 RAM

These are the following differences between  DDR 3 and DDR4 RAM  -:     

·        the module of DDR4 RAM  looks very similar to a DDR3 module RAM in physical appearance.

·        DDR4 has 288 pins and DDR3 laptop RAM has 240 pins

·        DDR4 SO-DIMMS have 260 pins and DDR3 SO-DIMMS have 204 Pins.

·        DDR4 key has a notch at a different place its edge connector looks in the shape of a slightly curved “V” which facilitates insertion.

·        DDR3 is less power efficient as compared to DDR4.

·        DDR3  has less data transfer data rate as compared to DDR4.

·        The latest versions of laptops support DDR4 RAM instead of DDR3.

·        DDR4 RAM density is higher than DDR3 RAM.

·        DDR4 RAM is more power efficient which leads to better work performance of a laptop than DDR 3.
