 3.06 GHz Pentium 4 with HyperThreading

Ace's Hardware has a new review of the new 3.06 GHz Pentium 4. The new CPU features HyperThreading, otherwise known as Simultaneous Multithreading or SMT. SMT allows the processor take advantage of thread-level parallelism present in multithreaded applications or multiple concurrent running processes by executing instructions from both threads simultaneously. To the OS, a SMT-capable processor appears as two or more logical processors (two in the case of the Pentium 4) that multiple threads can be scheduled on. Though this does not provide double the performance, it does allow the processor to be utilized more efficiently...increasing overall performance/clockrate.
