64bit question?

Hi all, i'm running a 2.8 prescott @ 3.2gig and i have been considering the
athlon64 for a second system. if the athlon64 is a 64bit proc what bit is my
P4 running at? i wanna know the comparison between the intel P4's and the
new athlon64 chips. i'm looking at a 3000+ (754pins), price is almost the
same as my prescott. the AMD is 2000mhz and the intel is 2800mhz so there's
got to be a difference in performance somewhere for them to be almost equal
in price but different speeds, right? i got an ASUS K8V as a birthday gift,
so this is the board i'm considering.

thanks in advance,
confused

imagine the AMD as a V8 engine at low RPM, and the P4 as a moped engine
about to blow up.

The AMD64 isn't faster than P4 because of 64 bits (since it requires a
64 bit OS to work in 64 bit mode, 32 bit CPU's can't operate in a 64-bit
OS.) It is faster since it has a much higher IPC (instructions per cycle).

Not too sure about that. I'm told the performance difference is due to the
on-die memory controller. Maybe shorter pipelines too.

In 32-bit mode, the performance difference is due to the memory
controller. In 64-bit mode, the additional speedup is due to an increased
number of registers. The x86 architecture has been plagued with a
cripplingly small number of registers since its inception, AMD took this
chance (designing a new instruction set) to remedy that.

As I said higher IPC. The on-die memory controller gives more IPC....

All that contributes to overall performance, but I assume the main reason
is clock cycles per instruction are less than the P4. I really don't care,
but the programmers guides for each cpu used to give the number of clock
cycles per instruction if you want to research it. One must remember that
the cpu's are very diferent even though they use the same instruction set.

correct, the IPC is just an overall indicator, where things like on-die
memory controller or cache or the design of the APU or whatever contribute
to the overall IPC.

I must admit the Intel engineers are doing a very good job at pushing moped
engines to their limits

I would have to agree here, Intel's 64 Bit instruction set differs from
AMD's
64 Bit instruction set.
Only good thing I can say about the LGA's is Price.
Unless you want to get a P4 3.4 EE (775 Pin LGA, newegg has them for 1,019$)

Not really, 4GHz P4's have been cancelled. If they where doing a very
good job, they would have announced 5GHz P4's instead, in time for
Christmas to keep there Marketing dept happy. Only thing Intel engineers
seem to be capable of at the moment is, throwing more cache on there
CPU's. Al while Marketing makes up Christmas songs about how wonderfull
32bit is and how the public isn't ready for 64bit yet and dosn't need it.

I know where I would rather be, not in fantasy land.
