There's also a massive tradeoff for when the error condition actually occurs. If an exception does get thrown and caught, that is comparatively slowwww.
The author pointed out how exceptions are often faster than checking every value. If your functions throws an error often enough that Exception handling noticeably slow down your program, surely you got to take a second look at what you're doing.
It depends what kind of errors you're talking about. Suppose you're implementing retries in a network protocol. You can get errors pretty regularly, and the error handling will be a nontrivial amount of your runtime.
