Dual core question

    I have a dual processor xeon box here in work. It's very fast. A delight to use....however....I rarely go above 50% CPU utilisation (100% of one CPU) because most applications aren't threaded.

    Dual core CPU's are the next "big thing", but might I see a performance drop if I'm using it to play single thread games? (for example)

    I'm sure threading will be in all the next gen games, but I'm wondering about current ones.

    well according to what I read sofar, you are right, allthough the 3.2 GHz performs as well as a 3.2GHz Prescott, you won't have much use for the second core while in that game.
    however, you will notice a performance difference, for example if you are ripping a DVD or encoding a DIVX movie for example as the OS will allocate that operation to the second core while the first core is used sololy for your games.
    so in short words, you will be able to multitask, with the resources offered.

    Thats correct, a dual core 3 ghz processor will give the same performance in games as a 3 ghz processor. While multi tasking will be improved, it really needs an NCQ enabled hard drive to be effective. I saw a dual core test on some site(might have been anandtech) which showed that dual core and ncq cut burning/ripping a DVD in half.

    Anyway, I find it extremely strange that Intel are giving priority to desktop users rather than to the server market, seeing as very few consumer programs can actually utilise a dual core.

    There are some games that support SMP. Anything using the Quake 3 engine for a start. I'd image the Quake 4 engine will follow suit. But I don't think gaming is an area where you're really going to see the benefits of dual core until probably 2006. You shouldn't get a performance drop (like with Hyperthreading), but if it's just gaming performace someone's after then a similarly priced single core would suit them better.

    have a look here for the benchies
