    Re: Intel or AMD - Future proof?

    Another vote for A64. It is more future proof and if you desire it will probably have more upgrade paths in the future (in terms of processors). I think the Intel chips will have to change soon as they are already doing with their mobile line, lower clock speeds and more efficient. The A64 still have room to get higher clocks on the same socket. If you do alot of multitasking maybe go for the HT technology but a friend of mine has the A64 3000+ and he says it multitasks very well.
    Either way you'd probably be happy, but you might have more $$ left after the A64 purchase.

    Re: Intel or AMD - Future proof?

    A couple of questions:

    What is LG775 compared to the other intel architectures, in terms of benefits?
    What's the difference between the 939 v 754 socket for A64 - is it worth the extra $$?

    the main benefit of lga775 is that it can safely deliver more power.

    that's not what intel says, of course, but when you consider that their cpus are DISSIPATING over 100W of heat (and CONSUMING more than that), it was getting to the point that nearly ONE HUNDRED AMPS of current was running through those small pins on socket478. LGA775 has a much greater contact area so the current has a lot more copper to carry it.

    you sure about that ? 100 amps is a LOT of power, most houses have a 200 amp breaker box

    Re: Intel or AMD - Future proof?

    amps is not power. amps is CURRENT, or the number of elecrons passing through a conductor per second (one amp is the number of moles of electrons that passes per second).

    voltage is not power, either. voltage is, in simple terms the power per electron (measure).d in Joules per Coulomb, where a coulomb is one mole or 6.022*10^23 electrons.

    Power is the amount of work done, and it is measured in joules and watts. Power=voltage*current. 100AMPS at 1.4V is 140W, which is about the power consumption of a P4 (CONSUMPTION, not DISSPATION). Dissipation is the waste heat whereas consumption is the actual power used.

    a wire's diameter is DIRECTLY related to its ability to carry current. 100 amps through even many of those small pins is pushing it. LGA775 makes the diameter, and thus the effective guage, of the conductor quite a bit bigger, and thus more able to safely carry current (that, and the number of power pins is more than s478, too).

    also, those house breaker boxes have heavy guage wire leading into them (which can carry lots of current). I highly recommend some education in how electricity works as it doesn't seem that you know (not meant as a flame, but education in things makes these forums a better place to visit).

    Yep, at full load the higher end P4s can easily draw 100 amps, but they are not drawing that through the wiring in the house. That's 115v, a socket 775 is around 1.4. It's all stepped down.

    PSU takes the 115v AC and converts it to 12v DC, then the motherboard converts that to 1.4v and the CPU gets it.

    Re: Intel or AMD - Future proof?

    Intel right now is. But future proof is never future proof. If you had to buy today I'd get an intel lga775 and processor and the board needs pci express and ddr-2 support.
    Well I won't back down, no I won't back down You can stand me up at the gates of hell But I won't back down Gonna stand my ground, won't be turned around And I'll keep this world from draggin' me down.Gonna stand my ground and I won't back down

    Why would you get the Intel? Is it because it has PCI-X and DDR2 or just because it's Intel?

    steve's blown up this bitich with some basic electrical equations.... try not to fry too many basic readers neural pathways. LOL just playing. But if you want to good reading on it "neural computation" try this:

    PS- A64 should last alittle longer. If AMD keeps to its plan of making the duel core a 939pin.

    It really matters on the person buying the system.

    Is he keeping his AGP based card or going all out with a new system?

    As of right now I see no real reason to have PCI-X and DDR2, I mean if you take a i875 system and a 925X system the 875 still beats it in most apps.

    Plus to much is changing right now, you have nVidia coming out with Intel chipsets in 2005, and a new AMD SLI nF4 chipset with weeks. Plus duel core CPU's and so on and so forth. I know you can't look back after you buy a system because its always changing but if you wait for the right time you can get the right setup that will last a bit longer than if you jump right on the train.
