Not exactly. The name of the game with GDDR memory is "speed on the cheap." To do this, it uses a parallel bus with data rates pushed to the max. Not much headroom for things that could compromise signal integrity like socketed parts, or even board traces longer than they absolutely need to be. That's why the DRAM modules are close to the GPU and they're always soldered down.

Also, the latency with GDDR7 is pretty terrible. It uses PAM3 signaling with a cursed packet encoding scheme. At least they were nice enough to add in a static data scrambler this time around! The lack of RLL was kind of a pain in GDDR6.

GDDR chips already have very high latency.

Like the gtx 970 with 3,5 + 0,4 memory.
