Hard Drive Performance: H2benchw

We tested the eSATA controller of all but one 790i Ultra SLI motherboard for RAID 0 performance, comparing it to the 790i Ultra SLI’s integrated controller, as well as that of Intel’s X48 chipset. The XFX nForce 790i Ultra’s third-party eSATA controller wasn’t tested, since it lacked RAID support. The board was instead chosen for NVRAID testing, though.

JMicron’s JMB363 finished both first and last in access time, depending on motherboard implementation; JMicron’s simpler JMB362 also tied for first on the unnamed mystery board. Interestingly, Nvidia’s and Intel’s integrated controllers provided the same performance here.

Drive interface bandwidth was also a dead heat, with the Intel integrated controller only slightly behind.

The 790i mystery motherboard continued its slight bandwidth lead across all read tests, while Intel’s minimum speed dragged it to the bottom of the chart.

What we said about reads also applied to writes, but notice Nvidia’s integrated controller also lagging.

    This was ALL OF THE AVAILABLE 790i Ultra SLI MOTHERBOARDS: Other graphics brands with NVIDIA reference boards INCLUDING EVGA are selling the same unit as XFX, even with the same BIOS (except for the boot logo). XFX was the only one who cared to send one.

    Who would pay four hundred dollars,when you can just buy a P45 for 100-150 dollars which has roughly the same real world experience as an X48 or 790I?
    Nah,I'd rather buy better and more reliable parts-such as power supply,processor,GRAPHICS CARD,and maybe go buy a rifle :P

    $400 for a motherboard? What the hell is wrong with the X48 Express that people would rather consider buying a 790i? And it can't be because of SLI. Makes more sense to buy the X48 and Crossfire.

    If you want SLI you're going to need an SLI motherboard. The article specifically stated that the reference design motherboard was almost as good in many ways as the winning board, but far cheaper.

    The site only has two awards, one is for top value and the other is for "best of the best". It's hard to award a $350 motherboard for top value, but it's not so difficult awarding the "best of the best" even if the price is outrageous

    It does! Well, sorta. If you want the absolute fastest rig on the planet, you're going to need at least two, possibly three, GTX280's. But if you can wait a few days or maybe a couple weeks, you might be surprised at how well a Crossfire set of HD4870X2's can perform using an X48 motherboard.

    My point is that,even though you could theoritically have 3/4 GPU's all at once,you won't get nearly as much performance as you'd want.A simple 750I or P45 chipset will do nearly the same job.

    It is a foxconn board i bet.I just read a review elsewhere with same stuff except it had an x48 chipset."All manner of goodies are bundled with the Black Ops: a 120MM fan, a plastic dry ice cooling pot for the Northbridge, and a Plexiglas "benching table" for open-air use."
