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.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.
