Intel Haswell-EX to adopt DDR4 in early 2014?

Posted on Wednesday, April 04 2012 @ 18:55:14 CEST by

VR Zone breaks news that Intel plans to adopt DDR4 memory with its Haswell-EX high-end server processors in early 2014, while desktops will have to wait until 2015.
Our sources say that, while the mainstream Haswell 4-core platform will still stay on DDR3 - and nothing wrong with that, since by then DDR3 will approach 3000 speed grade - the high end Haswell-EX 4-socket platform, with each chip having 16 or so cores, will for the first time, support DDR4 memory, in 2014. These monstrous chips, allowing upwards of 60 cores on each four socket mainboard, will bring a new meaning to a 'multi-core monster'. On the memory side, since DDR4 brings lower power consumption with 1.2v power supply, as well as better parity protection and recovery from errors, the benefits are there, even without the speed increase.

For the desktop side, the 22 nm Haswell and its 14 nm Broadwell successor would share the same LGA1150 socket, therefore both supporting DDR3 memory only, with DDR4 support likely only with their 2015 successors and a new microarchitecture at that time. So, here we have a one-year lag between high end and the low end for the new generation memory support, with the low end being the late one this time.
