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 OpenBenchmarking.org within 1303255-FO-GCC48INTE29.
For some workloads, there isn't much to see...
For other workloads, there is only a slight improvement to see out of GCC 4.8.0 over the year-old GCC 4.7.
GCC 4.8.0 isn't regression-free.
There are a few very nice performance gains with the new Free Software Foundation compiler.
Compilation times are mixed.
