LPDDR5 is soldered so It should be quad channel 4x32-bit or 128-bit in total. DDR5 could be as a single channel 64-bit DDR5 module in a DIMM slot or soldered, but in that case one DIMM slot should be empty. So you still can make a dual channel from It.Are the new chips that use LPDDR5 using single channel or dual channel? I have seen mixed info. Single channel would be such a waste. Dual channel would serve the iGPU well.
