14 DAY TRIAL // DDR4 memory won't make it to the consumer market before 2015, maybe not even before 2016, but the server industry is already seeing sample shipments.
Crucial is the company that most recently started sending such samples to its prospective customers.
The samples come in a variety of capacities, but run at 2133 MHz / MT/s, which is twice the speed that DDR3 offered when it first came out.
It's also pretty high, even compared to overclocked DDR3 performance. Sure, there are 2500 MHz DDR3 modules out there, but they are rare, and 2133 MHz is still really fast for them.
Not only that, but DR3 memory clocked at over 2 GHz operates at 1.5 or 1.65 V. In comparison, the new Crucial DDR4 RAM makes to with 1.2 V, while eating 40% less power than the RAM it will eventually replace.
Furthermore, when used with the Intel Xeon E5-2600 v3 CPU family, it doubles memory bandwidth from 8.5 GB/s to 17 GB/s.
All in all, DDR4 definitely seems to be living up to the hype. I can only wonder what sort of monster modules will debut once companies start to overclock it, in the next few years. The lower voltage definitely allows for greater OC headroom, if nothing else.
