The Brazos Review: AMD's E-350 Supplants ION for mini-ITX
by Anand Lal Shimpi on January 27, 2011 6:08 PM ESTThe Price: Around $100, The Motherboard: MSI's E350IA-E45
AMD expects most E-350 motherboards to sell for around $100 in etail. For lightly featured boards, I've heard this estimate is about right. It's once you start adding WiFi, passive cooling and other enhancements that costs creep up to around $130. Even at $130 that's not a bad deal. We're talking about better pricing than most ION boards but with much better performance.
AMD sent over the first Brazos motherboard ready for prime time, MSI's E350IA-E45. The mini-ITX board features two DDR3 DIMM slots (a Brazos feature, there's still only one 64-bit memory channel off of the APU), four 6Gbps SATA ports and a PCIe x16 slot (electrically x4). On the I/O panel MSI provides both VGA and HDMI out for video. For audio you have the options of running audio over HDMI, coax, optical or 1/8" stereo outputs. There are a surprising number of USB ports on the back of the board: 6 x USB 2.0 and 2 x USB 3.0 driven off of the very familiar NEC D7202 USB 3.0 controller. There are two USB 2.0 headers for front panel or case USB as well. There's unfortunately no WiFi support on board, all you get is a single Realtek RTL8111D 10/100/1000 ethernet port.

The MSI board doesn't support overclocking, so all results are at the CPU's stock 1.6GHz frequency.
Power is supplied by a standard 24-pin ATX PSU connector (older Atom/ION boards sometimes only used a 20-pin connector) as well as a 4-pin ATX12V connector. The Hudson FCH is passively cooled while the APU features a small, and unfortunately audible fan. ASUS is working on a passively cooled E-350 motherboard which I should have within the next week.

At home in my desktop machine I have a 4-lane PCI-x hardware RAID card with four 1.5TB drives configured in RAID 5 for speed hand fault tolerance. For a while now I've been wondering how the i/o performance of a good RAID card would fair if it was moved to a low-power (e.g. Atom- or Brazos-based) mini-ITX NAS system. I've been googling for a review of this setup but not been able to find anything conclusive.Think a lot of people would appreciate if you guys could give this a try and report on your findings!
Thanks Anand!

Well you should know - dont the raid cards have their own smarts & put little work on the cpu?My guess is it would be a great unit for a dedicated server. In the old days, many dedicated servers kept their 486 pcS for a decade as they ran fine.
a post above linked to a comparison of running pciE graphics cards at 1,4,8,16 lanes, & the difference between 4 x &16 by was slight. I imagine its the same with raid cards.

Anand, I didn't see what hdd you used for the tests. It would be very interesting to see how this platform performed in some of the benchmarks with a ssd. I know pcmark & vantage productivity benches use hdd test's to a certain degree.This really shows either how poor netburst was as an architecture, or how good existing sub 10w designs are.

It seems like the E-350 was built for overclocking. Especially on the desktop or with any cooling solution that has an extra 10 Watts of thermal headroom. Sooner or later someone is going to release a mini-ITX board that can OC an E-350 up to 2.5GHz and beyond. Right? It's not like the new intel cpu where you cannot overclock it, right?bjacobson - Saturday, January 29, 2011 - link
yeah I definitely want to overclock it!In a laptop when you've got an 8-10 hour battery life, if you know you're only going to need the laptop for 4 hours today, why not just crank up the speed? Great having that option.

"Unfortunately in modern titles that's not always enough to have a playable experience, but with older games you should be able to do more with Brazos than you ever could with Atom or even ION for that matter. The CPU/GPU balance in the E-350 is good enough that I feel like Llano could make for a pretty decent value gaming machine."Given that Zacate/Brazos performs at the level of 5+ years old midrange desktop CPU with midrange GPU and considering the quoted statement above it would be very interesting to see some actual performance data taken in titles that Zacate/Brazos *can* run at bearable FPS rates.
You could look up your performance charts from 5 years ago, dig out the old titles and rerun the benchmarks with those titles on Zacate/Brazos. This should give people better idea what they can expect from this generation of APUs. Sub-20 FPS rates in modern titles at rather low resolution and with all details at minimum isn't exactly what people have their sights on when deciding whether to shell out money for their new toy. Comparison with other crappy graphics that is on par with 5 year old solutions may give AMD's platform some edge over competition from Intel's camp, but it utterly meaningless as nobody is planning to use it in such setting.
Myself, I'd *love* to see some factual data from titles such as CoD2, DiRT, Doom3, etc. - the games you were referring to in the paragraph quoted above and all of which you already have reference benchmarks of (in order to have something to compare Zacate/Brazos against, without having t rerun all the benchmarks with old software titles). Such a benchmark with usable performance and enough eye candy will help put Zacate/Brazos' use in gaming setting into perspective, very much unlike those ~20 FPS tests you did above.
These merely indicate that integrated graphics of today are still useless for gaming.

Hm that's a good point. Likely I'd be playing a copy of UT2k4, perhaps quake 3 online, or some older online RTS. How do these fare at those games?cjs150 - Friday, January 28, 2011 - link
Nice review.There is a passively cooled E-350 board coming out. The review convinces me that this will be the right choice for the HTPC for the main room.
Why: TV already connected to an AV receiver so an E-350 system can use the HDMI connection to the AV receiver. E350 more than powerful for BluRay, fine for some light web surfing, ripping music. Maybe stick a TV tuner in as well and that is the main room sorted.
I have no intention of playing modern games on it so lack of power is not a problem. I have a bigger PC in study to rip movies if it takes too long on the E350.
But I also have an Atom based system. Again passively cooled. I use it as a server for the home network. It works just fine. It was cheap, ultra easy to build and just works. The fact that Atom is rubbish does not matter because as long as it can shift data round the network I need nothing more.
So every CPU has a purpose, just with some we have to look hard

AMD might score technical successes with its new lineup (Bobcat, llano, Bulldozer), but it will have trouble marketing them if only meaningless C Series, E Series, A series (Llano) and whatever Series (Bulldozer) are used.last time I looked, a C350 and E350 were Mercedes-Benz models, while CSeries is an upcoming Bombardier jet:
http://en.wikipedia.org/wiki/Bombardier_CSeries
In addition the numbers seem meaningless. Even intel's Core naming scheme is clearer than AMD's.
AMD simply needs 3 distinct marketing names that the general public will understand for its 3 new product lines code names: Bobcat - Llano - Bulldozer. "Fusion" and "Vision" just don't cut it anymore, as they have already been used for years by AMD.
One can easily see that there is a problem is the naming scheme when OEMs have to use the Zacate and Brazos code names to try to describe the product, like this example:

Yeah...the naming scheme ASUS and ACER use makes people mad when choosing laptops :)
