I liked this (older) overview article for more context on DDR6/LPDDR6: https://hothardware.com/news/jedec-ddr6-lpddr6-revealed

Especially:

[...] Where DDR4 memory officially topped out around 4266 MT/s and the fastest LPDDR5X available is around 10 Gbps, LPDDR6 is going to start with a 10.667 Gbps per-pin data rate, and is expected to scale to 14.4 Gbps.

Okay, starting out where we are now might not sound that impressive, but keep in mind that typically a new memory technology actually starts well behind the fastest memory speeds of the current tech. The earliest DDR3 memory supported 800 MT/s transfer rates, while DDR2 memory available for enthusiasts was clocked at 1333 and even 1600. Similarly, when DDR4 debuted it was the sluggish DDR4-1866, while DDR3 had been hitting 2133, 2400, and even higher speeds for some time.

When DDR4 just came out is was somewhat subpar relative to DD3 (and very expensive on top of that).
