AMD 64 fsb?

800MHz is the simple answer.

The complex answer:
AMD64 currently has a "FSB', or better called a HyperTransport Link, of 800MHz Up - 16Bit AND 800MHz Down - 16Bit
It is Full-Duplex (Transfers data up and down at the same time).

The standard Pentium 4 quad-pumped FSB runs at:
200MHz (800 Rated) Up - 32Bit or 200MHz (800 Rated) Down - 32Bit
which is half-Duplex (Transfers data up or down, one direction at a time)

The total theoretical bandwidth between the two comes out to be equal (6.4Gb/sec) but being full-duplex is more efficent in reality. PLUS being low latency and having the link to the CPU be free of memory bandwidth makes a big difference.

all 3 of them have the same fsb?
Correct. Thought the FX53 has a completely unlocked multiplyer. The other two, you can only decrease the multiplyer, if that helps at all. :P
