It is only a matter of time now before we will see the adoption of the new DDR5 Memory as a new “standard” for PCs. The next series of Alder Lake processors have been seen with support for dual-channel DDR5 memory.
Although we all know that DDR5 memory is arriving, it has been quite difficult to determine exactly when we might see them in action. Following a report by Videocardz, sources are suggesting that Intel is planning to use DDR5 memory in the launch of its 12th generation Alder Lake processors.
The site has obtained information about the memory controller of Alder Lake-S. This generation should come after Rocket Lake, and thus probably end up in the 12th Gen Core. The information tells us that Alder Lake will get variants with DDR5 support, for both one UDIMM per memory channel and a variant with two DIMMs per memory channel. Again (for some chips) support is added for ECC memory for error correction. Tiger Lake-H also appears to be working on (improved) ECC support.
It is also worth noting that Intel will add this alleged DDR5 support with the introduction of a new platform, which will probably be called LGA 1700. In addition, AMD and Intel would switch to a new platform with the same new generation.

It should be noted that, at the time of writing, neither AMD nor Intel has specifically confirmed which of their future processor series will make the initial transition to DDR5 memory. That said, however, clearly being a fairly hot property in terms of new technology, one is likely to follow the other in fairly quick succession.
With Alder Lake-S expected to hit the market around 2022-2023 (which is not very clear, for now), it gives us a pretty solid indication that the transition period between DDR4 and DDR5 is still there, but a bit far from us.
