    is there signifigent difference between a pentium 4(not ht) and a dual core pentium d 820? which one is better if so? are there any applications that make use of dual core capability? i know games do not so the 820 would be a step down in terms of games, right?(against a 3ghz p4) but is overall speed increased as a result of the dual cores or are they useless unless there is programs there that use them? i know the extreme edition 840 is the best of both worlds, but im focusing on the above two.

    any answers much appreciated

    stress.. What are you actually talking about?

    Surely are you are not comparing a non hyper threaded P4 to a Dual Core P4..

    Dual cores see a 10-20% reduction in power in most apps compared to single cores at the same speed. But in 2 years time that looks set to change. If you like doing more than one
    thing at a time like encode a DVD and play music while browsing the net get a dual. Hyperthreading helps but its going to fall by the wayside. Also pentium dual core are really just 2 pentium 4s slapped together. Not exactly the best archetecture.

    P4 (no HT) & Dual Cores. Yes you will notice a big performance difference.

    The Pentium Dual Cores, at the moment, have a very poor architecture. If you want a Dual Core, you're far better off getting an AMD chip.

    what about the pentium d dual processors, the lesser option of the intel dual core range, any disadvantages or advantages over a single p4? im am comparing the dual "d" processor with a single p4, a valid comparison, i think, as the p4 has a higher clock speed than the pentium d

    Intel have been hyping the merits of hyperthreading for years.

    Still can't find a decent list of apps that benefit from it.

    And that's the bottom line - if you application and/or OS can't use hyperthreading then it would be marginly slower with it turned on. Bit like the old debates between 286 vs. 386 and 486 vs. pentium

    As for power Centrino's knock the socks off other intel chips when it comes to low heat. A seriously overclocked centrino can give a decent price/performance.

    It all depends on the apps you will be running - [let's not forget the old pentium pro ]
