Why are there no more upgrades to memory cards. I was told that the ddr3 were maxed size for cpus and ddr5 would always be just for gpus. We now have ddr4 in use for cpus. Will we have and new upgrades in the future?
Btw, I was told that the ddr3 was max by a memory manufacturer when I asked them this same question. It was a major company.

You're talking system memory?

The throughput/bandwidth of DDR4 is substantially more than any modern CPU can take advantage of.

We'll see DDR5 or something in future, when we're getting closer to a *need* for it.

You should probably do some reading, Wiki has most the info you want.

DDR is System memory
GDDR is memory for GPU's.

There are very distinct differences between the two, DDR is much slower over GDDR.
DDR3 was released in 2007
DDR4 2014
DDR5 2017

Generally, it takes 2-3 years to see new versions being adopted by manufacturers, none of these are compatible and require new hardware.

You're kind of flipping back & forth in those dates.

Prototypes/spec for DDR3 existed in 2005, with adoption (in motherboards) from 2007.
DDR4 proto existed in 2011, with adoption from 2014
A proto for DDR5 was announced in late 2017, with JEDEC spec (AFAIK) still in development. Estimated 2019/2020 adoption.

So your dates should either be
2005
2011
2017/18

Or
2007
2014
2019/20

I didn't get real technical with it just pulled up whats on Wiki which should be enough for most people. This doesn't even include DDR5 which is over here.

That's all I meant. You've gone with the "release" dates for DDR3 and DDR4 (when support was included in motherboards) but then used the year DDR5 has had a prototype created. Actual implementation of DDR5 won't be until 2019 at the earliest, not 2017

It depends on the application, new RAM is always available to Industrial and Server markets first and then consumers from 6 months to a year earlier with DDR3 it was 2 years earlier. I also remember reading something about high volume production issues but I can't seem to find where that was at.
