Just had a watch of this online, PING TISI from 1998 vs PING G400 Max from this year.

With an average of 19 yds between the drivers, that's at least one iron difference for the next shot, maybe two on a good drive. The difference between hitting, say, an 8 iron into a green or a 6 iron. More forgiveness and up to 2 irons difference into a green... I'll definitely take that.
So less than one yard improvement per year
