Ddr5 Will Double Bandwidth

DDR5 doubling the bandwidth over ddr4 is another step towards consolidating all of the different types of memory used in modern computers which is currently being shuffled around every way imaginable to see what provides the best bandwidth-for-your-buck. Already graphics cards can access system ram and use it for storage when they have heavy textures to deal with and the entire industry has already adopted the HBM2 standard already coming on the market that can require half the amount of memory to do the same job by merely moving everything around less often. Bandwidth on computers is simply exploding at every turn and it probably won't start to settle down for a few years, but doubling the bandwidth of something like system ram also makes it all the more attractive for new graphics cards to use which can, theoretically, already address somewhere in the neighborhood of 512Tbs of memory.

HP and IBM have made significant strides with memristors which can store data right where the calculations are performed allowing the fewest number of components to do the same amount of work the fastest. Not only that, but they are cheap to manufacture and can already be stacked on top of each other. They've been working on this technology for quite some time, but it is currently slowly coming on the market and we shall have to see what happens. That would leave the last piece of the puzzle exactly how to produce cheap copies, such as we might commonly burn on DVDs today, of all the terabytes and petabytes of data these new computers can eat for snacks.
