The new, higher-speed DDR4 DRAM generation gained significant marketshare in 2016, representing 45% of total DRAM sales. Previously, DDR3 DRAM, including low-power versions used in tablets, smartphones, and notebook PCs, accounted for 84% of total DRAM sales in 2014 and 76% in 2015, but in 2016, DDR4 price premiums evaporated and prices fell to nearly the same ASP as DDR3 DRAMs. A growing number of microprocessors, like Intel’s newest 14nm x86 Core processors, now contain DDR4 controllers and interfaces. As a result, IC Insights expects DDR4 to become the dominant DRAM generation in 2017 with 58% marketshare versus 39% for DDR3.

The Joint Electron Devices Engineering Council (JEDEC) officially launched the fourth generation of DDR in 2012. In 2014, DDR4 memories first began appearing on the market in DRAM modules for powerful servers and a small number of high-end desktop computers, which had souped-up motherboards or the “extreme” versions of Intel’s 22nm Haswell-E processors for high-performance gaming software and PC enthusiasts, but volume sales remained low until 2015, when data centers and Internet companies began loading up servers with the new-generation memories to increase performance and lower power consumption. In 2016, DDR4 memories quickly spread into more data center servers, mainframes, and high-end PCs, accounting for about 45% of total DRAM sales versus 20% in 2015. In 2017, DDR4 will move into more notebook PCs, high-end tablets, and smartphones and is expected to hold a 58% share of DRAM sales.
