T-90 was designed in the same factory that builds T-72s. Separate factories made T-72 and T-80 and when Russia (after the collapse of Soviet Union) wanted to replace them with a more modern tank the two factories made competing models and the T-72 factory won. It has several upgrades including ones taken from T-80. (One big factor on the winner might be that T-80 was much more expensive. It was supposed to be the "quality" tank that is less numerous than the cheap T-72 and will only be given to elite units but I guess they either couldn't afford it or just decided that the idea was stupid.)
Slightly related on the topic, I tried to find a comparison between T-72 and T-90 but instead stumbled on this "non-intentional" comedy article:
