Four Z87 Express Motherboards For Three- And Four-Way SLI
Formerly a very exclusive component, the PCI Express switch that makes Intel’s LGA 1150-based platforms three- and four-way SLI-capable is now available across a range of high-end motherboards. Today we compare four premium enthusiast-oriented models.

MSI’s Z87 XPower comes up a second behind the pack in both iTunes and LAME, even after we double-check for rounding errors in iTunes. The actual performance difference is miniscule, and these are the only two applications in our benchmark suite where this occurs.
We were looking for applications where the Z87X-UD7 TH’s slightly slower memory performance might hamper real-world performance, and might have found one in HandBrake. The difference is still too tiny for most users to perceive in real-world use, however.

iam2thecrowe Am i missing something here? I dont see the point of reviewing 3 and 4 way sli boards and not testing 3 and 4 way sli. Seems rather pointless since any average motherboard will perform well in adobe, productivity etc benches dependent on the cpu....Reply -
Crashman This was really just about finding any board that supports Nvidia's requirements about how that third card is connected. We found some, I overclocked them, now I have enough data to pick a board for the System Builder Marathon. But that only explains why overclocking took priority!Reply
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. -

The general benchmark set looks for unintended overclocking/underlocking, power and memory bandwidth issues, so you can see the actual performance difference. And there's still an overclocking section.
These boards had to be tested for general performance and stability like any other boards. The PLX controller is the equalizer when it comes to games.
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. -
Kraszmyl "internally-mounted external USB 2.0 port for ReadyBoost fanatics" on the asus z87.Reply
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. -
Memnarchon I would love to see Asus Maximus VI Extreme, but it seems ASUS didn't want to give a 2nd board and prefered the Z87 WS....Reply -
Traciatim where are the sli/crossfire benchmarks and comparisons with traditional non-switched setups?Reply
Hey guys, we have these awesome new setups for supreme graphics pumping power! Watch it zip files like every other board! -
duramax08 Why are they still making motherboards with PS/2 connections? Its time to move on, replace those baby's with some USB 3.0!Reply
