Difference Between

DDR1 vs DDR2 DDR1 and DDR2 belong to the recent DDR SDRAM (double data rate synchronous dynamic random access memory) family of RAMs. Both these RAMs store data in similar type of DRAM arrays. The Initial member of this family was the DDR1 (often called DDR). DDR2 followed DDR1. And, DDR3 is the member that followed... 

GDDR5 vs DDR2 DDR2 belong to the recent DDR SDRAM (double data rate synchronous dynamic random access memory) family of RAMs. The second member of this family was the DDR2. And, DDR3 is the member, which followed DDR2. GDDR5 (Graphics Double Data Rate, version 5) SGRAM falls in to the category of DRAM graphics...
