[citation][nom]balister[/nom]You are missing something. While consumers try to keep up, businesses and organizations like to use known trusted items before they move forward. As such, a lot of hardware for an organization typically lags behind what consumers are using because it known to be reliable where as newer hardware has not had that burn in time. Thus, older hardware is preferable to newer because it's been thoroughly tested.[/citation]
DDR3 is pretty old now, I'd say it's tried and true enough for more general use.
[citation][nom]__-_-_-__[/nom]there's absolutely no need for such. it's not like you are going to play crisys on a set top box or that you need 16gb ddr3 on your fridge control panel.DDR memory is not just used in "pc's". It's used in thousands of appliances. from dvd players to vending machines to small lcd's etc. it's overkill to use DDR3.[/citation]
The faster ARM processors aren't getting enough memory bandwidth with DDR and DDR2 so a move to DDR3 is justifiable. There's also mobile XDR which is even better, but then prices might sky-rocket by using Rambus technology. Either way, we would get better performance for lower costs and lower power usage by using DDR3. Higher capacities may also be possible, but I think that the capacity is less important than the other factors unless it allows the usage of fewer chips, improving upon the other factors even more.
Some (many) other applications of DDR memory may be overkill with DDR3, but at the least it would improve power usage so it's pretty much always justifiable unless DDR is cheaper for the job. It doesn't need to be used in higher capacities to be better, 16GB for a fridge isn't a good argument against it. Just because it's DDR3, it has to be 16GB? There are 128MB, maybe even smaller DDR3 chips. 256MB are the common chip density right now.
