I'm no techy but hyperthreading is just like taking a 2 16 bit apps and running them on one prosecer like there are 2 becouse there is a 32 bit cpu. you can split it in to 2 16 bit channels.. since there are not a lot of apps that are writon .. (none that I know of really) that run on 64 bits.. you can use that extra bit width buy splitting it. The cpu and OS has to suport it though hince the name hyperthreading.
