P4 400 & 533 FSB

[fw3308]

I am looking at upgrading to a P4 soon and am a little confused about why I am seeing similar speed processors from Intel but different FSB's. I am referring to the 2.4 ghz procs with FSB's of 400 and 533 mhz respectively. Can someone explain to me if there are any real differences other than the FSB and why was this done?

There is no other difference. It was done because a LOT of people who had P4 systems only had support for a 100MHz FSB. (Since that was what the P4 was initially offered at.) However, that not being enough, Intel upped the ante to a 133MHz for 'newer' systems. (Even though this was done a while ago.) Since both older customers and newer customers deserve support, the P4s come in both 100MHz and 133MHz FSB flavours.

This is actually not a new concept at all and has been done for years with both the Pentium 3 and the Athlon.
