What the article says around this equation
Now put the two scaling rates from the opening beside this. If grows at 3.0x per two years and grows at 1.6x, then — the intensity threshold a workload must clear — grows at roughly 1.9x per two years [ 4 ] . Each hardware generation raises the bar for what counts as compute bound. This is why a kernel that was compute bound two generations ago is memory bound today without a line of its source changing, and it is the single most useful thing to know about accelerator roadmaps.
