What is GDDR7 memory, and when will we see it?

(G)DDR7 comes right before the DDR8 memory specification. Eventually, it will be.

Will there be a GDDR7X memory?

Will there be a GQDR memory? We have been at "dual" for a really long time now.

GDDR5X and up is already QDR. Just a naming convention they don't want to change.

GDDR5X​

In January 2016, JEDEC standardized GDDR5X SGRAM.[28] GDDR5X targets a transfer rate of 10 to 14 Gbit/s per pin, twice that of GDDR5.[29] Essentially, it provides the memory controller the option to use either a double data rate mode that has a prefetch of 8n, or a quad data rate mode that has a prefetch of 16n.[30] GDDR5 only has a double data rate mode that has an 8n prefetch.[31] GDDR5X also uses 190 pins per chip (190 BGA).[30] By comparison, standard GDDR5 has 170 pins per chip; (170 BGA).[31] It therefore requires a modified PCB. QDR (quad data rate) may be used in reference to the write command clock (WCK) and ODR (Octal Data Rate) in reference to the command clock (CK).[32]

GDDR6​

It is a type of GDDR SDRAM (graphics DDR SDRAM), and is the successor to GDDR5. Just like GDDR5X it uses QDR (quad data rate) in reference to the write command clock (WCK) and ODR (Octal Data Rate) in reference to the command clock (CK).[1]

Good to know, wow. Learn something new every day. It's also ODR (octal) for the command clock.
