Does anyone out there know what hyperthreading is?

Intel is hanging a lot on its HyperThreading (HT) technology. In fact, HT is the focal point of Intel's new line of software compilers introduced recently that the company says will "pave the way for Intel's HyperThreading technology." Indeed, the new compilers will help to allay observers' concerns after Intel failed to have its compilers ready when it introduced its first HT-ready processors earlier this year. Intel has said, for example, that performance gains of 25% are achieved when an application runs on an HT-capable Pentium 4 processor while many of these touted performance gains will hinge on the compiler. Program-wise, Intel's HT, which enables a single physical processor to create a simulated logical processor to run multiple tasks at the same time, will lend greater performance to its 3.06 Ghz and faster Pentium 4 processors, independent of clock speed, to a wide range of applications. If Intel's claims indeed hold true, the benefits will be applicable to conceivably any computationally intensive program. That includes high-scale transaction-oriented computing, financial, engineering and scientific digital media, gaming, and special effects applications, or in short, any application that runs the CPU at full throttle with more than one thread. The maximum 25% improvement in performance will be measured by standard benchmarks, such as frames/ second for graphics applications.
