Dual Core has a complete set of all registers, memory etc and is therefore two complete CPU's. HTt allows two processing paths except that it does share some of the hardware processing elements.
Be aware that Intel also makes a Dual Core in which both cores also are HT.
So in one sense Dual Core may be a replacement for HT.
The Dual Core performance will become more worthwhile as software gets developed to use each core at maximum efficiency.
Of course, at this time the Intel Dual Cores are fairly far from the most efficient design because of the poor communication path between the two cores.
Maybe wait until Intel gets their design finalized. [but that may require a new chipset/mobo]
hi there. I currently have a pentium 4 3ghz with HT. I am looking at upgrading my second computer. Basically i am gonna replace my second pc with the 3ghz Ht. In the master 1 i will fit it with the dual 2.6 Pentium D. Am i wasting my time or will the performance be just as equal. Is it true that the HT has been replaced with dual core tech?
