    Moore's Law states that processor speeds will double every two years. If you've been following processor releases lately, and I know every true Unreal fan follows them in the same fashion as the Quakers follow religion, then you'll know that recently there's been some stagnation in the new processor's speeds. Hopefully, that stagnation is a thing of the past:

    The Motley Fool has a great article about the new technology and its future implications.

    "These advances may one day lead to faster computer chips and less expensive components for optical communication networks."

    Looks like they missed a bit here:

    "This doesn't mean that the computer parts will cost the consumer any less. It just means that companies will make more money on sales because the components cost THEM less money."

    I'm pretty sure Moore's Law states that the number of transistors in the chips will double. Not the actual speed. Although more transistors should equal more speed, I think. I'm a CS major, we just use the damn things. Any electrical engineers in here who can tell us what more transistors does?

    Damn straight. Costs savings in any business are rarely if ever passed on to the conusmer these days.

    Hmm, shouldn't a CS grad student know how transistors affect processor speed ;)

    Moore's Law is usually interpreted as, "the number of transistors on integrated circuits doubles every 18 or 24 months". Some say 18 months and others say 24 months. A graph from the 8086 to the Pentium 4 shows a trend close to 18 months. However, from the Pentium to the Pentium 3 the doubling was closer to every 24 months.

    More transistors does generally equal more speed. However, simply doubling the amount of transistors will not double the speed. Something must be done with the extra transistors to improve the speed of the processor. The most obvious cause for transistor count increase these days is the use of 64 bit and multi-core processors.

    Improvements that resulted in more transistors being crammed onto circuits

    On board cache
    Pipeline technology
    Superscalar technology
    Branch prediction
    Data flow analysis
    Speculative execution

    The problem that CPU manufacturers are hitting up against is that the circuits are beginning to become so small that quantum effects are taking place.

    IBM came out with a technology that helps a bit (SOI I think) but the fact is that the material between transistors isn't providing enough isolation such that exchanges between logic gates go unperturbed.

    There was some talk about using shorter wavelengths (UV), using aloys, nanotubes, and other far-fetched ideas but the fact is that general purpose cpu processing power is going to stagnate for a few years while Intel and others figure a way of getting around today's barriers or switching to an alternative tech which would probably be costly seeing the investments these companies have made in the various plants they've opened to switch to a lower-submicron manufacturing process.
