The Brazos Review: AMD's E-350 Supplants ION for mini-ITX
by Anand Lal Shimpi on January 27, 2011 6:08 PM ESTFinal Words
With the settlement done and no DMI license in place, it's clear that there won't be another ION from NVIDIA (at least not based on x86). What Brazos is however is the ION successor that NVIDIA never built. For just over $100 you'll be able to buy a mini-ITX board with an E-350 that's faster than Atom, faster than ION and more feature rich than both. While I don't believe Brazos has enough CPU power under the hood to be a truly high end HTPC, it's easily good enough for a low cost, value HTPC. Popular codecs are well accelerated and with full DTS-HD MA and Dolby TrueHD bitstreaming support Brazos is solid. Flash acceleration is also present although it looks like there are still some kinks that need to be worked out there.
Overall performance is much better than Atom, particularly in single threaded applications. Brazos and the E-350 can make for a very affordable email/web browsing machine, and run those applications much faster than Atom could. As our more complex workloads showed however, the E-350 is limited to the same type of general usage models as Atom (with a bunch of new media and gaming options). You can run heavier apps on the E-350, you'll just be far better off with an Athlon II instead.
The Radeon HD 6310 proves to be a good match for the Bobcat cores in the E-350. There's not much value in adding a faster GPU via the on-board PCIe x4 slot as most games will be at least somewhat CPU bound. The resulting CPU/GPU combination is something that's typically as good as, if not better than Intel's Core i5 661 in games. In some cases the Radeon HD 6310/E-350 combination nips at the heels of Intel's Core i3 2100. 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.
Just as was the case with Atom, Brazos isn't going make for a very powerful primary PC. Load up the thread count or throw heavier workloads at it and the E-350 doesn't look all that much better than an Atom D510. What it will give you however is better single-threaded performance than Atom and a much better feature set. Brazos makes those secondary or tertiary computers you build much better than they would have been otherwise with Atom. I would like to see more CPU performance out of the platform and I'm not too keen on meeting the single core versions, but viewed through ION glasses Brazos looks good.
For AMD, Brazos has to be exciting. The company finally has a value offering that it doesn't have to discount heavily to sell. Brazos does very well against Atom on absolute performance, die size and price. The E-350 isn't the most powerful Fusion APU we'll meet, but it's a great way to introduce the family.

Hi Anand, as many of us are interested in using zacate in a NAS - could you run a quick truecrypt benchmark? I'm especially interested in AES-256 performance. Additionally, network throughput would be great, too ;)Something else: you measured 24 watts idle power consumption. Could you provide more details on your test platform? Others had engineering samples with as little as 11 watts at idle. I'm guessing you used some 850W-rated PSU? ;) Anyway, thanks for the review!

With such a low clock speed and such low power draw and a desktop platform, which can easily provide power but needs some more performance.. you'd think AMD would have put a proper Turbo mode in there. 1 thread 2.0 GHz, 2 threads 1.6 GHz - easy.MrS

First Thanks to Anand for doing a HTPC review for this chip, I've been waiting on this since your initial comments in Nov.But I'm kind of disappointed after reading the review. While it definitely looks like a better alternative to atom+ion i was just expecting a bit more horse power from it.
I was hoping for a product i was certain would have the power to do downloads, archive extraction and other CPU intensive processes in the background while doing 1080p playback or running an emulator in the foreground. And from the review i just don't see enough power to be sure my media and data-storage processes without potentially maxing out the CPU under certain combinations.
Looking forward to next gen discrete solution to replace my mid-tower HTPC.

I'd like to see a clock for clock comparison of Bobcat, Athlon II, Phenom II, Atom, Core, Nehalem, and Sandy Bridge.From what i can see in these graphs, Bobcat performs about 60-90% of Athlon II clock for clock.
I look forward to seeing overclocking of bobcat :)

Zacate (board) ~$100WiFi ~$25
small Case ~$75
PSU ~$50
4GB RAM ~$50
widescreen LCD ~$125
storage ~$100
around $500 for a good enough complete system, but of course you can always get cheaper case, PSU, storage, LCD and 2GB RAM

The mini-ITX boards based on Brazos are quite good as it seems. They surpass Atom for HTPC's and have more features like more sata ports. I would like to see a comparison with about 5 mini-itx Brazos boards by Anand. Also, if you have a power supply that is rated for max efficiency at about 15-30 W, you can accurately compare the power figures between Brazos boards and Atom. I've seen some reviews and they use power supplies that are rated at about 300W; their lowest reasonable efficiency is 10% load, that isn't designed for 15<P<30.MrMilli - Monday, January 31, 2011 - link
I would really like to see a comparison against the Athlon II 250u.jamesgor13579 - Monday, January 31, 2011 - link
Until it can replace my ION/Linux/XBMC system, I am not interested. AMD has been doing well on the Linux front recently, but I don't know about their video decode.Metaluna - Monday, January 31, 2011 - link
I'm also interested in how these boards perform in Linux (or even if the new GPU is supported at all in current mainstream distros like Ubuntu 10.10). I'm interested in building a small nettop, mostly for web browsing but possibly HTPC use at some point.Jeffk464 - Tuesday, February 1, 2011 - link
"The good news is 1080i60 works just fine.Brazos’ GPU also fails all of our deinterlacing tests,"
The second sentence follows the first one and seems to directly contradict it. I was planning on buying one of these for a htpc and the ability to play 1080i60 as well as 1080p24 are absolutely critical. 1080i60 is one of the main standards of broadcast(over the air TV) and 1080p24 is the standard for blue ray. So my question then becomes since the author seems to have contradicted himself can brazos handle the interlaced 1080i60 content? This article should have cleared things up not made it more confusing.
