The platform Intel X99 and the Haswell-E processors will hit the market by the end of 2014 or early 2015, it will be the first “home” platform (this is Intel’s most expensive and ambitious components to date) with support for DDR4 modules, instead of the DDR3 ones.
While we wait, developers are showing their own modules for this kind of memories. Crucial has showed during the CES various DDR4 modules in DIMM format for desktop computers, servers and even laptops with SO-DIMM modules, though it’ll still be a while until we see portable chipsets for DDR4 support, they’ll be oriented for ITX boards with support for this kind of memory.
These models will work at 2133 MHz while consuming only 1.2 v, similar to many DDR3 modules (but after years of evolving) but with a much lower consumption. The high-end Ballistix model will reach 3000 MHz.
