Hello,
I am looking into getting an I7 processor, but I don't know the difference between and Ivy Bridge or a Sandy Bridge and the benefits of either. Does anyone know what this means?

Ivy bridge is newer, generates more heat but give a little more performance.
Sandy bridge came out i think either end of 2010 or in 2011 and ivy came out this year, SB are cooler.

Here is an article you should read:

Also, there are dozens of threads with this very question here on Tom's. Take a look at some of those as well. This site contains a wealth of info if you take a little time to research what is here.

Good luck!

Given the same clock speed, Ivy Bridge is faster by 5% on average so an Ivy Bridge i7 running at 4.0GHz is basically equal to a Sandy Bridge running at 4.2GHz.

Ivy Bridge uses less power. On a full load, Ivy Bridge uses around 15w - 20w less power.

PIC-e 3.0 is supported by Ivy Bridge. It offers more bandwidth for graphic cards, but no current graphic card is limited by PCI-e 2.0's bandwidth yet. Maybe two graphic card generations from now a $400+ "Radeon HD 9xxx" or "GTX 8xx" graphic card will begin to be limited by PCI-e 2.0.

Ivy Bridge CPUs does not dissipate heat as well as Sandy Bridge CPUs. When not overclocking, it'll be fine. The heat prevents it from being overclocked as high as Sandy Bridge. But this is offset by the average 5% increase in performance.
