Hypertransport is a bus architecture. Used to be called Lightning Data Transport. On AMD64, it's how the CPU communicates with the rest of the system (other than RAM). On nForce2 boards, the northbridge communicates with the southbridge via Hypertransport too. That's what it's used for.
Hyperthreading is, as I and others have explained, a way for P4s to increase their processing efficiency in a few apps by making it look like you are running a multiprocessor system. It is not the same as true SMP. It can and does make some apps run slower. However, it can make a few select things run better and can improve the feel of multitasking in Windows because splitting up threads and sending them to a fake CPU is apparently smoother than Windows' scheduling for a uniprocessor system. |
