Multicore workloads do tend to hit RAM bandwidth limits before they hit power constraints. If you do the math, running at max frequency and core utilization would usually imply you could only access a byte or so per core clock cycle. Perhaps a mere handful of bytes for the highest-performance systems with in-package RAM.
Historically most devices were serving antivirus and snooping. Ai is the first time they are being used for actual computing again. They will be kept saturated.
