Yii really beats CI in all aspects.
But the most important aspect that makes Yii so great is that the DEV team really listens to user opinion when new features are requested.
Yii memory usage is bigger than CI's but the execution time is less.
I know this because i just rewrite a huge CI written site in Yii. But, YII comes with so many features(events,behaviours,native hmvc,,auth,rbac,etc) and makes use of all php goodies in a nice manner.
When CI will be able to do what Yii does now(after a few years in my opinion) it will be too late .
