Why exactly is energy wasted during this phase?
Are you expecting hardware to become obsolete much faster? But that only depends on TSMC's node cadence, which is still 2-3 years. Therefore, AI hardware will still be bound to TSMC's cadence.
GPUs are different than CPUs.
They’re way more efficient at matmuls, but start throwing branching logic at them and they slow down a lot.
Literally a percentage of their cores will noop while others are executing a branch, since all cores are lockstep.
But yes, a lot of energy wasted in the growing phase.
