What advantage do mulitple cores give?

   The new trend in multi cores on a processor is like what they used to do with increasing Ghz. First they came out with dual core, then they moved to core 2 duo. So if someone has a mother board which accepts 2 processors and both are core 2 duo processor which is 4 cores, does that mean that you open up 8 instances of Adobe Premiere, and each rendering occurs on its own core? Or does it mean that 1 instance of Premiere or other number crunching software will work not quite 8 times more efficiently? Or have hardware programmers not yet gotten around to implementing multicore functionality yet?

   I would love to say that "So Many Systems, So Little Time" - by Julia Camenisch in Videomaker's Hi-Def Guide (winter 2006) has the answers for you. Sadly, this article does little to shed light on hardware differences, editing systems, or anything else, for that matter.
   
   Instead, "the Moving Picture - Meet the New Beast" by Jan Ozer in the January 2007 issue of Event DV, not only answers your questions, but does so relative to video editing purposes. I recommend you get that issue and read page 72.
   
   As far as that goes, I heartily recommend Event DV to all event videographers. Other than their maddening policy of trying to limit authors to a single page, it's an excellent magazine.
   
   In short - no you do not open multiple windows of your NLE. Hyperthreading is what programs had to be written to take advantage of, but I believe (OK, I've only scanned the article) Core 2 Duo machines make just about any program run faster. They even run faster than single core CPUs that are rated at a higher clock rate.

   I just made up random info about an 8 core system in my previous post. But I guess Intel is actually working on doing this weird thing. It was unveiled at CES behind closed doors and written about at PC Mag, dated January 8th 2007.

   It was super exciting for me when the pentium 3 chips came as dual processors with their blazing sub 1Ghz speeds.
   
   I can't even imagine what the possible applications are, for these multicore systems. Maybe predicting the weather will be easier with all these processors telling me to put on a rain coat or snow boots.
