    Leading edge 32-bit performance
    Support for future 64-bit applications
    40-bit physical addresses,48-bit virtual
    16 64-bit integer registers
    16 128-bit SSE/SSE2 registers
    Supports PC1600 to PC3200 DDR Memory
    72-bit DDR memory
    Up to 3.2 GB/s memory bandwidth
    One 16-bit link up to 1600MHz
    Up to 6.4GB/s HyperTransport bandwidth

    whats all that mean? im mostly interested in the "bandwidth".

    im currently using a athlon XP 1.4ghz.

    AMD Athlon™ 64 processor overview
    The AMD Athlon 64 processor is the first and only Windows®compatible 64-bit PC processor. The AMD Athlon 64 processor runs on AMD64, a revolutionary technology that allows the processor to run 32-bit applications at full speed while enabling a new generation of powerful 64-bit software applications. Advanced 64-bit operating systems for the AMD64 platform from Microsoftf Red Hat, SuSE, and TurboLinux have already been announced, and they only run on processors with AMD64 technology.

    With the introduction of the AMD Athlon 64 processor, AMD provides customers a solution that can address their current and future computing needs. As the first desktop PC processor to run on the AMD64 platform, the AMD Athlon 64 processor helps ensure superior performance on today's software with complete readiness for the coming wave of 64-bit computing. With AMD64 technology, customers can embrace the new capabilities of 64-bit computing on their own terms and achieve compatibility with existing software and operating systems.

    Great performence in 32-bit apps.
    Support for upcomming 64-bit apps.
    Able to adres more then 4BG of memory.
    Additional instuctions for greater performence.
    Support for fast DDR Ram.
    72-bit, dunno
    And 'bout this bandwidth, the CPU can transfer more data in one cycle, higher performence.

    right. it can handle data in larger chunks than the older athlons, so the data spends less time queued up & waiting to be processed.

    I am still unconvinced that purchasing any CPU at this time would be such a wise idea. Unless, of course you have lots of dough...

    Especially this new 64 bit stuff...why pay for it when most apps are not 64 bit? The price is too high, in my opinion. Maybe wait until there are actually programs that use 64 bit instructions.

    I am sure by then there will be an Athlon 4000+ available for a decent price.

    I am not sure if you made a misake or not but the current P4 DDR 400 dual channel mobos all already do 6.4 GB/sec.

    i agree, it's not a good time to buy a CPU right now, unless you've got a lot of money.

    64 bit chips are expensive, but i wouldn't buy a 32 bit CPU either since 64 bit could become the-way-to-go sooner than we expect if software programmers are quick to jump on the bandwagon and make 64 bit versions of their programs.

    well, i wouldn't get a 32 bit CPU unless i really needed an upgrade... in which case i'd just get the fastest one available at a low price ($100 USD or less).

    but yeah, if you're not in dire need of an upgrade, i'd suggest waiting 6 or 12 months for the price of 64 bit CPUs to come down. PC components come out in improved versions so quickly that old ones don't stay expensive for very long. top-of-the-line PC stuff is hardly ever worth the price, as far as typical desktop applications go... it's more about bragging rights than anything.

    NETWEISER..in addition the L1 and L2 cache are pretty much like RAM that is built into the processor...its VERY fast...the more of it you have, the faster it will go! The Pentium 4 has 512KB the Pentium 4 Extreme Edition has 2048Kb...which on test didnt help very much. I also wouldnt think it would be smart to buy one...unless you have a board and ram that will be compatible with like an XP 2400...cuz thats not much..but if u gotta buy the mobo, ram, and cpu it aint worth it

    Actually, the P4 EE has 2048 kb level 3 cache and 512 l2 cache.

    It would be wiser at this time to wait a while for what appears to be a mid-range AMD 64 or opteron. To aviod a high price or performance that soon out date

    when improving one part doesn't help, it's usually a sign that there is a bottleneck somewhere else in the computer. there's no such thing as a computer without bottlenecks (a place where one part isn't keeping pace with the other parts). so if improving the CPU cache or front side bus doesn't increase performance, it might be because the system RAM or the PCI bus or something else is holding the CPU back.

    at best, upgrading one area just shuffles the bottleneck to a different area.
