Key difference between DDR3 vs DDR4 ram- UnderRated Tech

Let’s compare ddr3 vs ddr4 ram. Double data rate third generation and Double data rate fourth-generation, Synchronous Dynamic Random-Access Memory in short RAM.

Double Data rate 3 (DDR3)

Released in 2007,

For refreshing its content it performs autorefresh and self-refresh, DDR3 consumes less power than DDR2, self-refresh is used for low power consumption. The DDR3 clock speed varies from 800 MHz to 2133 MHz. Mostly the clock speed varies from 1600 MHz to 1800 MHz.

It uses 30% less power and also can transfer data twice faster.

Random Access Memory (RAM)

Double Data Rate 4 (DDR4)

DDR4 can only perform self-refresh so that it consumes less power than the DDR3 The clock speed of DDR4 Ram is 2133 MHz, which is minimum, and also there is no defined maximum clock speed for DDR4.

Let me tell you the difference between DDR3 vs DDR4.

ddr3 vs ddr4 ram
1 Double Data Rate version 3 (DDR3) Double Data Rate version 4 (DDR4)
2 The purchase cost is less than DDR4 It is costlier than the DDR3.
3 Both auto-refresh and self-refresh performed in the DDR3 RAM In DDR4 only self-refresh is performed.
4 DDR3 costume more power than DDR4 but it consumes less power than DDR2 DDR4 consumes less power than DDR2 and DDR3 because it only performs a self-refresh
5 The Data speed is compatibly slow than DDR4 The DDR4 data speed is faster than the DDR3
6 16GB is the maximum memory limit present in DDR3 There is no maximum memory limit in DDR4
7 DDR3 clock speed varies from 800 MHz to 2133 MHz In DDR4 2133 MHz is the minimum clock speed and there is no defined maximum clock speed in DDR4.
8 DDR3 has low latency than DDR4 DDR4 have more latency than DDR3
9 DDR3 was used in older computer systems. Currently, DDR4 is used in mostly all the computer system worldwide
