ASUS Crosshair V Formula-Z Review: Cream of the Crop for AM3+
Results: SiSoft Sandra 2013
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 therefore to the PCI-E bus. 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.
In terms of CPU performance, both boards are neck and neck. Remember, these are pretty close together in terms of design and BIOS implementation. One would expect much the same performance, or at least hope for it! Memory bandwidth is equal for both boards as well. Asus typically does a very good job in extracting every ounce of performance from a chipset and board design.
File system performance is interesting. AMD’s SATA 6G controller is pretty good overall, though is slower than the current Intel Z77. The one advantage AMD has is the inclusion of six SATA 6G ports as compared to the two on the Z77. I am still confused as to why buffered writes are so slow on the AMD controller as compared to what we see on the USB 3.0 tests. The Samsung 840 Pro is darn fast though.
