There isn't an easy answer to that ... a lot of equivocating.
Palo Alto, Mountain View, Los Altos home prices started rising early in 2012. Palo Alto is still going up but the number of homes for sale and thus the number of sales is low. Cupertino has also been strong. Sunnyvale and Santa Clara are good but probably not pushed up as strongly.
When you start looking at neighborhoods the number of sales can be too low in a quarter to get meaningful statistics.
