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.
