AMD Sempron vs SI42

Hi all,
I was wondering why my Sempron SI 40 was capable of 2060 MHZ and has a better performance level than my other computer wich has a Sempron SI 42 stabling at 2095 MHZ.
The Sempron SI 42 isn't supposed to be more powerful?
Response: It could be because your laptop with the SI-40 CPU has better chipset, and/or more memory, and/or faster disk, and/or better video card.
Support 64Bits

Apparently so. Much to my surprise! I am running 32-Bit Windows 7 on My SI-40 I should try 64-Bit Windows 8 when its released. The SI-40 Should cope
