USB 3.0 To The Front Panel: ASRock Leads The Way

Socket AM3: 890FX Deluxe4

AMD’s current chipset advantage for both mainstream and upper-mainstream products is its added PCI Express 2.0 connectivity, which Intel currently limits in a fairly debilitating way. Those extra lanes mean that the 890FX Deluxe4 can support two graphics cards and two USB 3.0 controllers at full bandwidth.

The 890FX Deluxe4 supports a third card in x4 transfer mode, but PCIe 2.0 technology gives the extra slot twice as much performance as the x4 slots often found on Intel motherboards based on P55 Express. ASRock doesn’t even need to use up any PCIe 2.0 pathways for internal SATA 6Gb/s, since the AMD SB850 southbridge supports six of these ports natively.

Front-panel and rear-panel USB 3.0 are provided by separate NEC D720200F1 controllers, each on its own PCIe 2.0 x1 interface. Individual devices on each controller can be fed with the controller's total bandwidth, but any two devices on the same controller must share bandwidth.

Because USB 3.0 and USB 2.0 use completely different data pathways, the new connector uses 19 pins, rather than the former 9-pins, to provide two ports with the two separate technologies.

    Now all they need to do is lead the way with a standardized case connector.

    Thank you ASRock for bringing USB3.0 front header on your motherboards! Now i can expect a much nicer set-up in my case in an upcoming build...

    I sure hope the standard connector comes out before this gets out of hand.

    Hopefully some other motherboard manufacturers catch on.

    You're looking at it, Page 1 photo. Other motherboard manufacturers are already using this same connector as mentioned in the article, so it should only be a matter of a few months before case manufacturers follow suit.

    ASRock responds to pleas? Maybe someone could plead for dual-gigabit-ethernet equipped SOC-chipped (atom? i3?) 6x sata2 motherboards, too. It's impossible to build your one-machine-to-rule them all firewall-server-htpc in a small form factor currently!

    Yeah i remember reading reports that Intel dithed USB 3.0 about 6 months ago in favor of the mb and new CPU research (P66, 67). Surprisingly they sold this tech or the design to ASROCK. Im sure they will eventually come around to implimenting this for ALL future motherboards.

    So would old cases be able to use this since it is just a connector?

    Revised cases could use it, if they had the new cable and connector. Remember that USB 2.0 and USB 3.0 are not cross-compatible, they use separate signal pins and share only power and ground with each other.

    They should have kept the board like the 890gx extreme 3 without all the legacy rubbish like floppy or pata, when looking at the boar layouts in comparison this extreme 4 just looks messy

    ASRock still markets in places where Windows XP prevails. That means that the floppy header is still more valuable than most of us would like to believe.

    What I take from this article is the fact that Inhell hobbles all the good features that AMD doesnt! And people wonder why I always recomend AMD? GET REAL.....get AMD for the performance you deserve! (this add brought to you by..........nobody, I just really like AMD)

    While I wouldn't go quite as far as Deadstick50, I did take from this article that P55 is just not the way to go; not if you expect any kind of future-resistance, i.e. to take full advantage of high speed USB 3.0 peripherals.

    Yeah, but look at Intels implementation of PCI-E, its chanelled wrong and limited in scope...i stand by what i said.

    If nothing else, I'm glad ASRock did this so other manufacturers will be forced to include front USB3. Manufacturers have been very slow to offer this, and it's nice to see someone begin to step up.

    It's not "Intel," it's the chipset and/or CPU; consider that X58 offers full speed and full functionality. A lesser AMD chipset (like 870) would chop out some lanes and/or features too.

    I got the x58 extreme 6 when it came out on Newegg and loving it so far, just wish it had more on-board USB 2.0 connectors.

    Yeah, like the second graphics card slot. Wait, that's another 16 lanes that can be used even if some were removed resulting in similar other stuff as the higher mobos. Sorry the fact that intel limited that entire platform to that low is insane and ridiculous.

    Asrock, you done good. You guys are always make boards with features other people dont have, or more of them. 870 board with 2 x16 lanes, more USB 3 than most, so on and so forth. Good prices too. Now just make sure they are quality.
