For those having computers with AMD FX "Bulldozer" processors, here are some benchmarks showing some of the performance improvements made -- and regressions -- in upstream GCC and the Linux kernel that can be found when upgrading to the forthcoming Ubuntu 12.10.
As AMD Bulldozer hardware isn't benchmarked on Linux as frequently as Intel's Sandy Bridge and Ivy Bridge processors, this article offers just a glimpse of the Ubuntu 12.10 performance for the latest-generation AMD desktop CPUs. More Bulldozer Linux benchmarks will come in future articles with looking at the compiler performance, compiler tuning, kernel comparisons, and much more for an updated look at the FX-8150 on Linux. See the many previous articles on Bulldozer that happened around the time AMD introduced Bulldozer last year.
The same AMD FX-8150 system was used for all testing while comparing the stock configurations of Ubuntu 12.04.1 LTS and Ubuntu 12.10. The Ubuntu 12.10 development snapshot was from last week.
