The next generation of DDR3L has arrived. New chipsets and processors from AMD® and Intel® now support low voltage memory operating at 1600MT/s (aka 1600MHz). DDR3L-1600 memory has a module classification of PC3L-12800, which effectively means the peak data rate of the module is 12.8GB/sec (see table). That’s approximately a 17-percent improvement on memory bandwidth over DDR3L-1333.
|Module Classification||Module Peak Bandwidth|
|800 (DDR3-800)||PC3-6400||6400 MB/sec. or
|8500 MB/sec. or
|10600 MB/sec. or
|1600 (DDR3-1600)||PC3-12800||12800 MB/sec. or
|1866 (DDR3-1866)||PC3-14900||14900 MB/sec. or
In servers, the processor model number affects how fast the memory can operate. Higher model numbers support 1600MT/s, but may be limited by the number of DIMMs per Channel that are installed.
Some entry-level mobile and desktop processors, such as the Intel Core i3, may not support 1600MT/s memory.
Only the latest generation of chipsets and processors support DDR3L-1600 memory.

DDR3L-1600 effectively increases bandwidth over DDR3L-1333 by approximately 17 percent.
Quad Channel architecture such as those supported on Xeon E5 v2 and Opteron 6300 platforms increases memory bandwidth by up to 35 percent over previous Triple Channel architecture.
Some applications may require the maximum memory bandwidth available, such as 3D applications, CG, CAD and mechanical/industrial design, technical and scientific computing, digital content creation, video games, and many more.
