The problem with motherboard reviews is that we do not see the performance deltas that we used to due to the integration of so much functionality onto the CPU. Instead of comparing memory controller designs from VIA, Intel, and NVIDIA we are now left with the units built into the processors. AM3+ still uses HyperTransport to connect the CPU to the northbridge, and then onto to the PCI-E bus. FM2+ gets rid of HyperTransport and uses PCI-E to communicate between the APU and the FCH. As such, it is good to see if there are any particular variances between boards even though so much performance and functionality is already integrated into the CPU. We also take special note of I/O performance, as it can be affected quite a bit by a poor BIOS implementation.
All three boards seem to be evenly matched, but the Crossblade Ranger is consistently ahead by a point or two. The biggest difference seems to lie in the native USB 3.0 performance.
