Some (All?) P4s have this technology. Practically speaking, this means
applications see the system as having multiple processors. More than one
thread can run at once. So yes, multi-threaded apps benefit from this in

Seduced, shaggy Samson snored.
She scissored short. Sorely shorn,
Soon shackled slave, Samson sighed,
Silently scheming,
Sightlessly seeking
Some savage, spectacular suicide.
