I would suggest a different metaphor, since these days, CPUs also have a bunch of cores: * GPUs invest more chip real-estate in integer and floating point crunching (ALU, FP). * CPUs invest more chip real-estate in control logic, prediction and speculation. Not that these are the only hardware differences of course, like how caching works, and larger vs higher-bandwidth memory etc.
