Intel Developer Forum Spring 2003 - Day 2: Prescott Info Galore

Prescott New Instructions & Hyper-Threading Improvements

As we mentioned before, the Prescott core features 13 new instructions which are listed below:

As you can see, there are a number of complex arithmetic instructions that can be used in scientific and engineering applications. There isn't much information on the instructions available as of yet, but we'll be working today and tomorrow to get as much information as possible about them.

The two thread synchronization instructions are responsible for improvements in Hyper-Threading performance as they help reduce the collision of threads within the processor itself. Once again, we'll be looking to get more information from Intel as they make it available, so be sure to check back later as we do get more...
