The passage around this formula

This decomposition is also why a device’s peak number and its delivered number can diverge by an order of magnitude depending entirely on software maturity, with no change to the silicon — and why comparing two architectures’ peak numbers, without separately accounting for how mature each compiler is at extracting UcompilerU_{\mathrm{compiler}} , compares two different things that happen to share units.
