Compiler Tuning With Intel Ivy Bridge Processors
Written by Michael Larabel in Software on 5 June 2012. Page 4 of 4. 3 Comments

Some of the other GCC results were largely uninteresting.

With GCC 4.7.0 and the common computational code we commonly benchmark at Phoronix, with the versions out there now, there really is not anything to gain out of building with the Ivy Bridge target (core-avx-i) over Sandy Bridge (corei7-avx). This though will likely change as developers begin to write code that can better take advantage of these modern CPU features. The Ivy Bridge support within GCC will also continue to improve in GCC 4.8.0 and future releases.
