People in the West are always getting ready to live - Chinese proverb
Unlike Intel's "Smithfield" family, this expensive member of the Pentium stable will include not only a dual "Prescott" core, but also be kitted out with hyperthreading.
The reason for this is purely marketing, as far as we can see. The Smithfield "non D" processors are also priced far more reasonably than Mr D XE.
Now a chap has claimed online that overall performance for the Pentium D XE is poorer with HT turned on for this chip than when two separate CPUs are used.
He wonders if Microsoft has plans to patch the XP threads scheduler for dual core HT CPUs, as you can read here. ยต
