The RAM is inside the M1 package. That has to make a huge difference in memory access time; it probably saves about a nanosecond in each direction just because it's closer to the CPU. There's probably other stuff going on like little or no microcode compared to the x86 ISA. So yeah, it's plausible that the M1 is really faster in absolute terms than a desktop PC.
