Stands for Double Data Rate Type 3.. DDR3 is a type of SDRAM that is used for system memory. It is available in both DIMM and SO-DIMM form factors. DDR3 RAM is similar to DDR2 RAM, but uses roughly 30% less power and can transfer data twice as fast.
This unfortunately comes with an increase in latency as well, but the increased clock speed makes for quicker transfers while maintaining an overall latency comparable to DDR2 and DDR3. DDR3-1600 operated at a latency of CL11, which took 13.75 nanoseconds to initiate a read.DDR4-2133 sits at CL15 and performed a read at 14.06 nanosecondsâonly a 2% increase.he difference between DDR3-2133 and DDR4-2133 was negligible in a number of applications, ranging from Handbrake video conversion to half a dozen different games. DDR3 was slightly faster about half the time, and typically only a few percentages points separated the two memory types.
