Supposedly 128 GB although I doubt vendors will ship that much.

the snapdragon x2 elite extreme (X2E-96-100) SoC supports "128GB+" but qualcomm hasn't specified what the max limit is. this soc also has higher memory bandwidth (228GB/s over 192-bit bus) than the x2 elite.

128GB is what they can ship using RAM chips available today, but the SoC supports more.

128GB can't be the current or future limit for a 192-bit bus. There's a missing factor of 3.
