The passage around this formula
Everything else in this article follows from one observation about that ridge point: because has been growing at roughly twice the rate of B [ 4 ] , has been climbing steadily. A kernel whose intensity was comfortably compute-bound on one generation can be memory-bound on the next without a single line of it changing. Hardware progress moves operations across the boundary in only one direction.
