For example Apple uses HBM instead of DDR5. They also give the CPUs heaps of L1/L2/L3 cache to avoid memory access as much as possible. And some of the stuff they do with flash memory is just as expensive.

That’s the real reason Apple Silicon Macs cost so much and I’m more than willing to pay that price. But it’s also the reason those Macs are so fast.

How does Qualcomm compare? I have no idea.
