HyperThreading As In The Past
The new Xeon also still has Hyper Threading technology, whereby WindowsXP Professional or Windows Server recognizes four virtual processors.
In addition, with regard to the FSB clockspeed, Intel attaches great importance to the fact that the Hyper Threading introduced two years ago also profits from it: the bandwidth of the data bus of every virtual HT-CPU now amounts to 1.6 GB/s, instead of 1.05 GB/s.
