Question on FSB speed

[efrant]

Just a general question: say I have system with a 1600MHz-bus processor that runs at 3.0GHz and I have the exact same system with a 1333MHZ-bus processor (same generation) that runs at the same 3.0GHz. Assuming no overclocking or anything like that. Is there a benefit to the former system over the latter, all else equal?

As I understand it, front side bus hasn't existed since memory controllers became integrated. Are we talking about Core2Duo era chips?

Yes, Core2. Sorry I didn't make that clear.

If you have memory fast enough to match the increase in bandwidth of FSB you will gain increased memory bandwidth which usually doesn't provide much of a performance gain but in some cases it might like Winrar overall there shouldn't be more than 0-5% performance difference.

Thanks!

I had a pair of Xeon 3.33ghz processors with a 1333mhz fsb I got a sweet deal on a matched set of Xeon 3.40ghz with a 1600fsb and swapped out the 3.33ghz for the 3.40ghz.

Using Cinebench I got a score of 7.88 on the 3.33 ghz processors and a score of 8.11 on the 3.40ghz. So with the addition of 0.07 ghz processor speed and the additional fsb speed the performance improvement was nominal.
