a=openpgp; fpr=8B336A6BE4E5695E89B8532B81E806F586338419 The Apple M3 based devices follow the pattern of their M1 and M2 predecessors. One notable difference is that the M3 Max SoC has two variants: t6031 and t6034. t6034 has 14 CPU cores, 30 GPU cores and a combined 384-bit LPPDR5 memory bus while t6031 comes with 16 CPU cores, 40 GPU cores and a 512-bit wide LPPDR5 interface. These are the only apparent differences between those two SoCs.
