What is DDR3?

DDR3 is an abbreviation for double data rate version 3. It is a form of SDRAM that is commonly used for system memory. DDR3 which is available in SO-DIMM and DIMM form factors has dominated the systems hardware market for almost a decade in a row. In comparison to DDR2-based systems, computers with DDR3 memory can transport data from one spot to another at a substantially quicker rate.

What is DDR4?

DDR4 is an abbreviation for double data rate version 4. When it comes to the next generation of computing, DDR4 brings forward the most recent memory varieties. DDR4's lower voltage and enhanced transfer rates enable it to provide consumers with maximum efficiency and performance at all times.
