216 million functions involving a few FP operands is going to take multiple seconds of CPU compute if the entirety of the CPU cycles were efficiently dedicated

216 million functions involving a few FP operands is going to take multiple seconds of CPU compute if the entirety of the CPU cycles were efficiently dedicated to said compute, due to the single thread nature; so I would guess yes, it's a fair amount of compute for a phone or something that will use loads of cycles on other scheduled topics
