Does CPU hyper-threading have any performance effect on PC games?

Does CPU hyper-threading, such as the Core i7 has, have any performance impact on video games? What is hyper-threading mostly, and best used for? Will future PC games be programmed to make use of hyper-threading?

  1. does not make difference in i7
  2. There was a post around there a week or two that compared hyperthreading vs nonhyperthreading in various games. The conclusion is that they are effectively equal (HT won by a frame or two in some games, nonHT in others).

    Hyperthreading "On" does increase the heat on the CPU by a considerable amount (10c on mine)... I have it disabled to allow for a higher OC at lower temperatures, therefore increasing the performance of the chip at similar temperatures.
  3. resident evil 5 takes full advantage of I7 CPU check this link

    and by the way Bloomifield processors better than lynifield processors


    i mean the 9"s of i7 better than 8"s because it has 4.8 GT/s QPI instead of the 8"s wich have 2.5 GT/s DMI thats make the 9's uses HT better than the upgraded i5 the 8"s is just like i5 but little upgraded
  4. Is HT enabled by default, or do you have to enable it in the BIOS?
