The rapid development of the memory bandwidth of computer knowledge

5.6 years ago, 4 trillion memory can be regarded as a very cow computer, and now 4 m memory can only be ordinary, barely follow the computer configuration. Why is the bandwidth of the memory changing so much? This requires talking about the channel in memory. This article is about three channels in memory.

To say that three channels in memory, so to tell you what is the dual channel?

Dual-channel in memory is used to solve the CPU bus bandwidth than memory bandwidth much more than the memory bandwidth caused by the mismatch of the bus bandwidth. However, the bandwidth of the CPU bus is getting higher, so the bandwidth of the previous two channels can't keep up. This time, three channels have been introduced to solve the problem of too low memory bandwidth. If the single channel is only 1 memory addressing, then the dual channel is 2 memory addressing. Now the 3 channel is 3 memory addressing. So there may be n channels in the future ...

  Three channels compared to the previous two channels

The dual-channel memory bandwidth averages around 20gb/s, and now the three-channel memory technology can increase the average memory bandwidth by up to 38.4gb/s, up to a one-fold increase in bandwidth.

The above is about the computer knowledge of the rapid development of memory bandwidth . Memory bandwidth to quickly improve now can only rely on the continuous increase in the number of channels, not to improve the effect of a channel is nearly doubled, so the memory of our computer will continue to become more. The memory is also constantly getting bigger.
