I can see that what you really want to know is what performs better.
I'm 90% sure of the following!
The AMD XP is 'equivalent' to the P4.
You have to match up the speeds.
The AMD Athlon XP 3000+ is 'equivalent' to the P4 3000MHz
Note, when AMD say their processor is 3000+, it's not 3GHz, it's
actually a bit over 2GHz, but since more work is done by the AMD
processor in each cycle(Hz), it works out to be equivalent to a P4
3GHz processor. The 3000+ is a PR (performance rating).
P4 processors do quad pump the FSB, whilst AMD Athlon XPs only dual
pump theirs. Intel also makes use of the dual inline facility of their
dual inline memory modules, AMD does not. But for some reason, the AMD
Athlon XP works out equivalent to the Intel P4 in terms of
performance. (No doubt they each have their strengths and weaknesses
for specific types of applications). Each has a large fan base.

P4s and AMD Athlon XP both interface with a 64-bit data bus and have
32-bit registers. So there's no difference there. Only the latest
processors have 64-bit registers.
> also some AMD's have 1600 and 2000 front side bus
no, that is a PR rating for the processor clock. Nothing to do with
the FSB or max speed of FSB that is supported.
The FSB is the bus that connects processor to the memory controller
which is in the northbridge.
The memory bus connects the memory controller to memory.
The athlon 64 has the memory controller on the die (on the processor).
The processor and memory are connected directly. There is no FSB, and
probably no 'memory bus'. The names are different.
P4 FSB speeds supported vary. Those p4 processors supporting 200MHz
FSB quad pump it, so market it as 800MHz. That is where you got that
800 number from.
And AMD Athlon XP with a 133MHz FSB dual pumps it to 333MHz. The
latest AMD Athlon XP has a 200MHz FSB dual pumped to 400MHz.
