Intel Ivy Bridge Benchmarks On The GCC 4.8 Compiler

Following from this weekend's Intel Core i7 990X benchmarks on GCC 4.8, here are benchmarks of an ASUS Ultrabook with an Intel Core i3 "Ivy Bridge" benchmark as we explore how the new GCC 4.8 compiler affects its performance.

These are just the latest GCC 4.8 compiler benchmarks done on Phoronix with many other articles already having been penned in recent months from 4.8 development snapshots on both x86/x86_64 and ARM hardware. For kicking off a new week of benchmarks, I uploaded this morning some GCC 4.7.2 vs. GCC 4.8.0 compiler benchmarks from an ASUS Ultrabook running Ubuntu 13.04.

The portable system is powered by an Intel Core i3 3217U "Ivy Bridge" CPU with 4GB of RAM. A Linux 3.9 development kernel was running on the system while GCC 4.7.2 and GCC 4.8.0 were both built from source in the same configuration.

All of the benchmark results in full and other system hardware/software details and logs can be found on within 1303255-FO-GCC48INTE29.
