Lets get this straight:
Hyperthreading or Hyperthreading Technology (HTT) is an "implement" by Intel for some of their line of Pentium 4's, thus giving the name Pentium 4 w/HT. There is a similar implement on AMD's side of the bargain, ironically name Hyper Transport (HT).
Hyperthreading is just a technology to give a processor two "tasking layers". This should not be confused with two cores. HT helps the computer run faster because the computer can run two thread at the same time, not just one thread. Now what is a thread? A thread is a set of instructions that a program uses to run itself.
Normally, programs have to "wait in line" to be executed. The waiting is too slow to see sometimes. HT allows two people to go through the line at the same time. Dual core processors are like having two lines with one or two people going through at the same time.
Now to real-world performance. CPUs with HT only execute programs faster if that program can run support HT, which means the program is multi-threaded. Other programs that are single threaded will not see as much of a change in speed, although there is some increase.
