Raptor Lake only supports 64 GB officially (Raptor Lake U, P and H) and 128 GB (Raptor Lake HX), but the new ThinkPad P16v with Raptor Lake H has been announced with 96 GB of RAM - and its more expensive, thicker brother ThinkPad P16 G2 with Raptor Lake HX will be sold with 192 GB, despite Intel's official limitations.

Only the new AMD Zen 4 Phoenix supports
Ryzen 7040 Phoenix-HS APU for 4nm ultrabooks supports up to 128GB of RAM

The memory controller will allow the use of DDR5-5600 or LPDDR5x-7500 in dual-channel mode. Interestingly, the processors support 4 modules (even two-rank ones), while the total RAM capacity can be 256 GB. Of course, it is not a fact that many manufacturers will implement similar configurationsand laptops

I'm pretty sure Alder Lake and Raptor Lake mobile (U, P and H) as well as Zen 3/3+ officially only support up to 64GB.
