Samsung DDR4 modules offer 40% power saving

If you’re building a new PC then you want the fastest memory you can buy for your money. At the moment that would be DDR3 modules. But Samsung Electronics is pushing ahead with a replacement and has created the first 30nm DDR4 modules.
The good news is DDR4 is both faster than DDR3 while using significantly less power. A typical DDR3 module uses between 1.35V and 1.5V and can achieve data transfer rates of 1.6Gbps. The first 2GB DDR4 module only requires 1.2V while achieving a data transfer rate of 2.133Gbps.
While the speed increase at a lower voltage is impressive, those initial figures are set to improve even further. The use of Pseudo Open Drain (POD) technology means DDR4 modules will consume only half the electricity of DDR3. The speed of DDR4 is also set to increase as high as 3.2Gbps once new circuit architecture is introduced.
The end result is once DDR4 modules are in use we will see a noticeable performance improvement. If used in a laptop, the power saving is as high as 40% making your battery last that little bit longer.
Samsung is aiming for JEDEC standardization before the end of 2011, meaning we could see new modules appearing before the year is over. The first commercial modules look set to be 4GB
