Intel Unleashes Its First 8-Core Desktop Processor
Could someone give me a simple explanation of what exactly hyperthreading does?  They tout 16 logical cores and 8 physical cores in this new chip.  I've read the Wikipedia page on it, but it gets too technical.<p>I do molecular dynamics simulations with LAMMPS, and I've noticed performance on my laptop is best with 4 cores.  Using all 8 "virtual cores" is actually quite a bit slower.
