Already happened a few months ago. DDR5 doubled the number of memory channels in a normal desktop from 2 to 4. That’s 2 channels per DIMM.
Of course DDR4 still has lower latency today, but that should change next year.
Today the only way to reduce latency is to overclock your RAM. It’s pretty easy to get a $200 DDR4 kit to perform better than what you’d find in $5000 prebuilt PCs.

- Veliladon 5y agoIronically it makes it faster. TRP and TRCD numbers are getting so big compared to transfer clock rates that it's more efficient to double the bank groups and send data on more smaller channels vs speeding up a single one.
