QuoteQuad-Channel
Wrong.
If the RAM was using DDR5 SO-DIMM, it would have been called dual-channel (2*64-bit per channel (2*32-bit sub-channels)).
Using LPDDR5(X), it's called octa-channel (8*16-bit per channel).
Either way, they are different names for a 128-bit memory bus width, like 99% of laptops / desktop PCs are. Strix Halo, as a 256-bit, 256 GB/s, system, stands out.
