The latest benchmarks were published to OpenBenchmarking.org this weekend. The main addition is some early Linux virtualization benchmarks from the Piledriver-based eight-core processor plus there's two other large result files for those wishing to see how the FX-8350 4.0/4.2GHz processor compares to your own Linux system.
AMD FX-8350 Piledriver KVM Linux Virtualization - A number of Kernel-based Virtual Machine (KVM) Linux benchmarks on the FX-8350 when comparing the raw "bare metal" performance of the system to running a KVM guest through virt-manager and allowing it to tap all eight CPU cores. Xen and VirtualBox benchmarks from this latest-generation AMD hardware are still forthcoming.
AMD FX-8350, NVIDIA GeForce GTX 680, Ubuntu 12.10 - Many OpenGL / gaming benchmarks from Ubuntu 12.10 with the FX-8350 when paired with a high-end NVIDIA GeForce GTX 680 graphics card. To see how your system compares performance-wise, simply run phoronix-test-suite benchmark 1210276-RA-FXNVIDIAG81 to conduct a fully-automated side-by-side comparison.
4.5GHz Piledriver - Various open-source Linux benchmarks when the 4.0GHz eight-core CPU was overclocked to 4.5GHz. To see how your system would compare to this FX-8350 test-bed running Ubuntu 12.10, it's simply a matter of executing phoronix-test-suite benchmark 1210279-RA-AMDFX835008 thanks to the Phoronix Test Suite cross-platform automated testing framework.
On OpenBenchmarking.org are also many other AMD FX-8350 benchmarks. More proper tests will be coming after the weekend.
