When we have become accustomed to DDR3 the next standard is only two years into the future. Samsung has announced that the world’s first completed DDR4 memory at 16 GB for servers, with higher frequencies and lower energy consumption than before.
The new memory standard DDR4 is expected to appear in servers with Intel Haswell-EP, and AMD Abu Dhabi in 2014. Verification and troubleshooting of the server platforms often take up to two years, so it is only natural for Samsung to complete its first DDR4 memory for servers.
The world’s first completed DDR4 memory module comes in the form of a Registred ECC with 16 GB capacity, 2133 MHz and 1.2 V operating voltage. Registred ECC DDR3 memories operate at 1333 and 1600 MHz at 1.35 V. While the potential bandwidth has increase, the energy consumption has gone down by nearly 40 percent. This is not the limit of the new standard, it is exected to scale up to 4266 MHz at only 1.05 V.
The first memories are made with 30 nanometer technology, but Samsung says the first that will be shipped will be made with 20 nanometer grade technology. Capacities will be at 8, 16 and 32 GB, it is also possible that there will be higher clocked models than mentioned here. DDR4 is expected to use so called point-to-point topology, which means each module will work as its separate memory channel.
This is good news for servers that is constantly screaming for more bandwidth, but also retail where we are starting to see a need for faster memories as more components are integrated into our processors. Not the least the graphics processors that are quickly becoming faster and faster.
