QuoteQuad-Channel
It's dual-channel, like 99% of home (mini) PCs out there (some run in single channel, because they are only using one RAM slot, but are actually dual-channel). 2 * 64-bit per (SO-)DIMM slot.
AIDA64 measures 62416 MB/s (=62.416 GB/s).
Let's confirm:
Theoretical maximum: 89.6 GB/s = 128-bit * 5600 MT/s / 1000 / 8.
What any memory benchmark tool would measure: 65-85 % of the theoretical maximum: 69.66% = 62.416 GB/s / 89.6 GB/s. This falls perfectly within the expected range.
Quoteand light AI workloads.
Good that you added "light": Especially the prompt processing speed on a Radeon 860M and its only 89.6 GB/s is exactly enough only for light AI workloads (unless, of course, you are ok with waiting for up to many, many hours for a result).
Time that AMD makes a 43% (= 8000MT/s / 5600MT/s) bigger APU due to using LPCAMM2 / SOCAMM2 memory. Ideally, I'd like to see not only 8000 MT/s, but 9600 MT/s, because then it would not only be 43% but 71% (= 9600MT/s / 5600MT/s). If 9600 MT/s (APPLE M5 and INTEL Panther Lake are already using 9600 MT/s memory speeds) is only possible using soldered memory chips, well, then so be it (it's not like RAM breaks often and would need to be replaced). Only the prices need to come down, too.
