What Is The Difference Between Ddr3 And Ddr4

Ddr3 ram is backward compatible with the older ram generations while ddr4 ram is not backward compatible with the older generation s ram.

Ddr3 was introduced back in 2007 while ddr4 was introduced in 2014. Both ddr3 and ddr4 dimms are 5 inch 133 35 mm in length but the pins in ddr4 are spaced closer 0 85mm than ddr3 1mm. Both ddr3 and ddr4 are the versions of double data rate ddr. Difference between ddr3 and ddr3l.

On the contrary ddr4 ram has a 288 pin interface. Generally self refresh is used for low power consumption and ddr3 consumes low power than ddr2. Ddr3 specifications officially start at 800 mt s or millions of transfers per second and end at ddr3 2133. The main difference between ddr3 and ddr3l is the voltage specification.

One of the major differences of ddr3 vs ddr4 rams lies in their clocked speeds. Even though for ddr3 rams the clock speed ranges from 800mhz to 2133mhz manufacturers have moved on to make sure that the lowest clock speed is 1333mhz for ddr3. The speeds or the frequency of ddr4 rams are much higher than the frequency of ddr3 modules. The technical advances of ddr4 ram.
