Maybe this could help: Intel whitepaper on ffmpeg mosaic transcoding of multiple Full-HD streams at 30fps using a recent Xeon E3 CPU.

We do not provide assistance with load testing as it is too much of a drain on resources to help people do it properly.  By far the most accurate way is with real traffic.

I know this question is impossible to answer exactly but what roughly estimated CPU usage could I expect for conference with five 480p streams transcoded at 15 fps.
One room with common core i5 quad CPU, 5 simultaneous rooms, 10 rooms?

Correct, it is indeed.  Try it out and see.
 
Will SIPp do the task or your can recommend another (maybe simpler?) benchmark tool?
