Sandra’s CPU benchmarks also show all four motherboards essentially on-par, though its memory test shows the Z87X-UD7 TH slightly behind. With so few other optimizations to choose from, memory optimization has become the “secret sauce” of motherboard makers concerning LGA 1150 performance and memory overclocking.
That slight difference at least gives us something to look for in our real-world benchmark set, which begins on this comparison’s next page.
After spending two days per board on a "one week" article, I couldn't add more tests. The general benchmark set looks for unintended overclocking/underclocking, power and memory bandwidth issues, so you can see the performance difference attributable to each board's CPU and DRAM configuration differences. It runs from a .bat file, so it didn't add significantly to the article's completion time.
The PLX bridge that these all share represents the "great equalizer" when it comes to CrossFire and SLI configuration, so that portion of all three boards should be identical. I understand that things that should be the same in theory are occasionally different in practice. My apologies for not having the extra 1-day per board for additional tests.
I think testing 3/4 way sli would still be valid, as it doesn't always work properly, in the past there have been compatibility problems with certain gpu's/boards/firmware/controllers and certain benchmarks completely failed.
Those have nothing to do with readyboost. The internal usb ports are very common on workstations and you put CAD dongles and equivalent items in them so that you can lock them inside the case and don't have to worry about some one stealing them from the outside or them taking up an outside usb port.
Hey guys, we have these awesome new setups for supreme graphics pumping power! Watch it zip files like every other board!
