Excellence and Speed DDR3 Memory
DDR3 SDRAM is short for double-data-rate three synchronous dynamic random access memory.
Is the third generation strung together two files using the technology rate random access memory (RAM) for high speed data storage that is being done by the processor.
The obvious advantages of DDR3 memory compared to the previous generation (DDR1 and DDR2) lies in his ability to run four times from the bus clock speed mempry itself, so it can produce a higher bus speed and greater bandwidth throughpu.
Here's a brief explanation about the speed DDR3 memory which I took from the media pc sites:
Bandwidth greater throughput made possible by DDR3, thanks to the use of 8-bit prefetch buffer. Compared to DDR2 is still using the 4-bit and DDR that only use 2-bit prefetch buffer. That's why the resulting bus speed DDR3 will be able to achieve two-fold, when compared to DDR2 and four-fold when compared to DDR. This is also why DDR3 is first used to meet the bandwidth requirements of video memory on the card, especially for the series of high-end, where the need for fast data throughput bandwidthh inter-frame buffer is needed.
Frequency for DDR3 memory can certainly risen considerably compared to the DDR2. This of course is inseparable from the use of 8-bit prefetch buffer, or bebebapa circles refer to it as 8-n prefetch. In other words, this will double the bus width of internal SDRAM DDR3 DRAM cores with input / output buffer.

Thanks to this, no longer needed a faster core memory for increased data transfer rate of DDR3 compared to DDR2. Only by "outsmart" the buffer memory, in this case the prefetch buffer to work early.
It causes instant DDR3 can directly obtain the frequency bandwidth greater throughput than DDR2. Without the need to make changes to the massive increase in terms of semiconductor manufacturing.
With the use of external buffers that work faster, core frequency of the DDR3 can be seen more quickly with a core frequency of memory chips more or less the same compared to DDR2. Of course the way it gives a bad side as we said earlier. Increased memory bandwidth to also having a devastating effect on the increase in memory latency. And this certainly is not news anymore. And from the experience of previous RAM module technology transition, early versions do not provide significant performance improvements.
When compared to DDR2-800 SDRAM, with timming 4-4-4, 10ns, some of the high-end products will be able to reach 1066 MHz. This could be a competitor in terms of performance for DDR3. However, for a while yet released JEDEC standard specifications for DDR2-1066 SDRAM. And enable the transition to the use of DDR3 technology makes more sense for memory bandwidth performance considerations.
JEDEC (Joint Electron Device Engineering Council) has issued a formal specification that has been used as the standard for DDR3 SDRAM, the memory frequency between 800-1600 MHz. Can be seen in the table.
