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.
Buying a low-cost, high-efficiency platform is kind of like choosing a cable package. For a few dollars more you can always get a killer feature that you really want. But then it seems like the features that are still missing really aren’t that much more expensive. It's a clever scheme to keep you constantly thinking about the next-best thing just a few dollars up the ladder.
You might face the same sticky decision when it comes time to shop for that inexpensive PC: go for the budget gold, or spend a few extra dollars on a faster processor (and then a few more dollars on a better graphics card, and a bit more on more memory, and...it really never ends). But AMD is hoping that its Brazos platform gives you enough compute horsepower, enough graphics performance, and enough value to squelch that never-ending desire to push just a little bit further. If you want a solid idea of what the platform includes, check out ASRock's E350M1: AMD's Brazos Platform Hits The Desktop First.
Today we have eight different Brazos-based platforms, priced from $115 to $175. If you're dead set on saving money, one of these setups should be able to satisfy you. Now it's time to figure out which tier in this little sub-market serves up the best value.

The Zotac board actually is available on Newegg
http://www.newegg.com/Product/Prod [...] 6813500068
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.
Wow! AS-rocks!
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 yet this roundup is .... desktop boards.
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.
Cheers,

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.
These CPUs and graphics are pitiful for a desktop system. Might as well buy a cheap laptop and hook it up to whatever display you want. You can buy a Toshiba P6200 with 4GB RAM, 320GB HDD, DVD RW, webcam, wireless, bluetooth and W7HP 64bit for less than $400.
When you ran an Atom board comparison, you included performance data for an old Pentium (or Athlon; don't remember). This was very helpful, as I'd get a feel for how good/bad is 5 minutes for your workload. Of course, this was just an anchor point, and would be excluded from any value/efficiency graphs.
Does anyone else feel the performance graphs would be more meaningful with a typical Atom and a cheap Athlon X2 as points of reference?
These are not design to be purely performer, we all know that. Their purpose is to compete with the Intel Atom processors.
For all the data that's included in the chart, it's quite astonishing that there's nothing to distinguish which boards use SO-DIMMs and which ones use DDR3-1333. Most users are going to care a LOT more about this than whether or not there exists an internal parallel port connector.
All of these setups are about twice as expensive as they should be. By the time you add all the trimmings to build up a complete system, you're spending nearly what you would for an economy desktop where a $100 WD TV or $200 pre-built Atom machine would be a much better investment. Wrapping a $10 chip in a $165 board just makes zero sense. In fact, I'd be very interested in seeing a detailed cost-breakdown on one of the more expensive boards - I just can't understand how they could possibly be valued so highly.
I would have liked to see how these perform as an HTPC. Can the handle BD at 1080i? How is websurfing? Can they place facebook games that my grandkids love... usefull things like that. We already know these cant game or handle intensive apps so why waste time benching these...
Perhaps a future article.
Nice round up!!
I really would love to use the AMD APUs for a lower power server application.
Only problem is that the boards are all 4x PCIE and single nic. Come on! Let see something with dual nics and 8x PCIE.
Yea yea yea Llano here now, but hell I've love to have an E-350 with a board like this. Its all about the power consumption baby!
Trinity and Komodo are both Enhanced Bulldozer. As such, Trinity will not be using Zambezi cores.
The name "enhanced" Bulldozer had me guessing. I wasn't sure if the cores would actually be different in Trinity, or if it was the same BD cores "enhanced" with graphics. Did you read anything more detailed on it?
Does anyone else feel the performance graphs would be more meaningful with a typical Atom and a cheap Athlon X2 as points of reference?
Well I always appreciate more data, so yes.
Here's a helpful document...
