A 16 GB Apple Silicon MacBook Pro has about 65,500× more memory than this device shipped with.
At 2 MHz, the clock is roughly 1,600× slower than a single performance core of a 16 GB Apple Silicon MacBook Pro — and that is before counting cores, width and IPC.
All of this storage could hold roughly one modern phone photo.
