Amir Ban is right and I know that the world champion Junior4.5 was faster than
Junior4.6 because Junior4.5 was 32 bit when Junior4.6 was 16 bit thanks to
chessbase.

If you want to be fair you need to give Junior4.6 faster hardware or maybe to
ask Amir to send you the 32 bit version that won WMCCC(Junior4.5)

There is a small difference in the evaluation between Junior4.5 and Junior4.6
but the most important difference is the speed of the program and Junior4.5
is faster.

I remember that Junior4.5 was 20% faster at the time that Junior4.6 was
available.

I am not sure what is the situation today with the new hardware.
