The Brazos Round-Up: Eight AMD E-350-Based Motherboards

Deals

AMD’s Brazos platform, driven by the Zacate APU, offers a lot of performance per watt. It comes up short on features, though. Eight manufacturers try to change that perception by adding slots, controllers, and even overclocking in a couple of cases.

Overclocking

Only two of today’s motherboards are overclockable. Several others supported unsanctioned DDR3-1333 operation, however, and received a performance boost because of that.

Asus edges out Gigabyte, but we were really hoping to reach 2 GHz. 1840 MHz is still a little more respectable than 1808 MHz, and even that small overclock provides a noticeable boost to APU performance.

The difference between Asus and Gigabyte overclocking could be limited to reference clock, where one company uses different voltage levels than the other. Too much voltage can also hurt an overclock, as a result of heat

Four of today’s board’s support DDR3-1333, and two of those also supported reference clock adjustment. Remaining differences are due to slight variations in default reference clock.

    The Zotac board actually is available on Newegg

    http://www.newegg.com/Product/Product.aspx?Item=N82E16813500068

    Only problem is that it is $160 instead of $130

    Otherwise very nice roundup. I've been thinking of using one of these for a server/NAS.

    Odd timing for the roundup, Llano just came out, these will be discontinued asap.

    Not good for much save storage, but that wasn't tested. Would have much rather see an A8 board roundup since they are on newegg now. Picked up one myself for my htpc/storage setup.

    Uh no, Brazos is bast on the Bobcat core which is a low power version of Bulldozer. These are meant for ultra portables and netbooks, nettops, ultrathin notebooks and the likes.

    Llano is the entry level desktop APU until they switch from Stars cores on those to the newer bulldozer cores.

    And brazos has nothing in common with bulldozer.

    Net TOP. Meaning a low power ITX board. Brazos is merely a stopgap till AMD has the tooling to kick out tons of BD cores. Though I will agree this roundup is a bit late it is at least thorough.

    Good call--that board only recently became available, after this story was scheduled to be published. We've since updated the conclusion and price chart to reflect the market as of July 4th, 2011.

    Brazos is NOT a stopgap, it is meant for very low power applications. It's basically AMD's take on Atom style devices. Bulldozer is not meant to scale to this low power envelope. That's why there are already plans for Brazos successors. Ontario/Zacate will be replaced by Khrishna/Wichita. Llano will be succeeded by Trinity, which is Bulldozer based. Zambezi is supposed to be succeeded by something called Komodo, which I haven't read much about.

    Trinity and Komodo are both Enhanced Bulldozer. As such, Trinity will not be using Zambezi cores.

  • Well, aside from a few bits about Brazos being a stop-gap based on Bulldozer being wrong, the basic premise of "odd timing for a Brazos roundup" holds true.

    Llano for laptops is out-freaking-standing, Llano for desktops is amazing for cheap OEM-built desktops and small form-factor HTPCs. TBH, it shouldn't excite much of anyone else, nor was it intended to replace Phenom II + dGPU for enthusiasts.
