Joomla 3 requires a minimum PHP version of 5.3+.

Joomla 4 requires the latest PHP version 7+. Because PHP 7 uses a new model of engine called PHP NG which increases the performance two times as much.

Joomla 3 supports Mootools and jQuery libraries. But these are very slow and not frequently updated whereas they’re still active.

Joomla 4 removed Mootools to increase the performance overall.

While, they are moving to custom elements, which will be much faster, framework agnostic, and will also be fully accessible.
