Micron have officially announced they've pretty much putting the finishing touches on their first DDR4 modules. Initially clocking in at 2.4GHz (dual data rate) scheduled to rise to 3.2GHz the Micron parts are manufactured on 30nm and expected to debut at 1.2v (versus 1.5v for DDR3). The chip itself is a 512mb one, implying a desktop 'DIMM' size of 4-8GB. While a lot other news sites are (slightly) aburst with this, we do remember that Samsung actually minted the very first DDR4 module last year.
Ok to be honest we just Googled it, but at least we checked:
Either way, this is the penultimate step in a long process aimed at getting faster and lower voltage memory into computers. The standards authority JEDEC began defining DDR4 over a half decade ago and once finalised, official DDR4 production will commence by various manufacturers. Servers, followed by low-voltage applications such as smartphone and tablet processors are expected to be first to snap up the new memory, followed by desktops around 2015.
Extremely keen upgraders could in theory pick up their first part of a 2015 'Broadwell' based system at the end of this year. For the rest of us, we remain 'stuck' with DDR3, but given both AMD and Intel based systems seem to have an overkill of memory bandwidth right now, we should easily be able to stand the wait. Though 3.2 GHz just sounds awesome...
Goddamnnit, now we really want one.
