The new DDR4 memory has been under development for more than five years and is expected to bring higher performance and a reduction in power consumption. It also means that the end of DDR3 can be seen on internal roadmaps as it will slowly be phased out like DDR2 and DDR1 memory kits were as new DDR4 platforms come out across the PC spectrum.
PC hardware companies are coming up BIG in this space. Intel, Kingston, ADATA and a few others even showcased the new technology with prototypes, at the CES 2014 event in Las Vegas.
