Benchmark Results: Power Consumption

Three Sub-$500 AMD Brazos-Based Notebooks Rounded Up
By

All of the notebooks die when you hit ~5% of battery life, which is a fairly standard alarm for Windows 7.

This is the percent drop in battery life you should see in Windows 7 if you put the system into Suspend mode. Remember that Microsoft rounds off. For example, depending on where you are on the capacity scale, you may see a 1% or 2% drop over six hours for HP's dm1z.

Remember that IE8 is threaded (one tab, one thread). So, this multi-threaded benchmark includes navigation of Web sites, including scrolling calculated to a reading speed of about 200 WPM. On Amazon, we shopped for GPS units and common biology textbooks.

This session consists of the following run sequentially in the order listed:

  • 24 minutes of Wikipedia Reading (4 Entries): one tab per entry
  • 4 minutes of Amazon.com: two tabs
  • 3 minutes of CNN.com: two tabs
  • 2 minutes of Google Finance: one tab
  • 2 minutes of Accuweather: one tab
  • 25 minutes of Flash 10.1 (YouTube 360p, H.264, hardware acceleration enabled): one tab


This is a multiprocess benchmark in that it reflects some multitasking.

This session consists of the following:

  • 2 x 1000 word papers typed in Word 2010 at ~45 WPM
  • Four minutes of H.264 480p playback during some portion of word processing
  • 2 x 45 word emails sent via Outlook 2010 at ~45 WPM
  • Five minutes editing a large Excel table


Despite similar TSUP numbers, these results are going to differ because of the varying battery capacities in play. Remember again that Microsoft rounds off when calculating remaining capacity. Our metric is designed to show you how fast capacity will fall off if you use all systems under the same conditions over one hour.

All notebooks die when you reach about 5% of battery life, which is the standard alarm for Windows 7.

    they should have put a larger battery on these!

    I ordered a Lenovo X120e E350 4GB RAM Win 7 Pro for $529. Lenovo's build quality and matte screen made the deal for me. Personally, I think the DM1Z is hideous.

    Yeah, I also had a lenovo x120e. Build quality is excellent on those. I wasn't impressed with the performance too much though. It's was little bit slower than my thinkpad x61t core2duo L7500 which was from 4 years ago. But video playback was really smooth. It played 1080p mkv videos with only 30% cpu usage.

    Since I got my x120e with e-350 for $305, I eventually sold mine for a small profit.

    The D525 can only go toe-to-toe with the 3-350 if you only look at the results of multi-threaded benchmarks.

    Use the D525 then use the E-350 and you will not go back to the D525 and it will be obvious why.

    Impressive how much bias Tom's has these days... E-350 performs quite a bit better than Atom in pure CPU power and don't even get me started on the GPU performance. All in just ONE chip! As much as it hurts you Tom's, Brazos is a much, much better platform than Atom is.

    Strange how the first picture(from AMD) in the conclusion puts i7 higher than BULLDOZER!

    They wont put a large battery nor will they price it lower.Know why ,bcos the blue monster has found a new and novel way to continue its monopoly.

    I'll admit that is a bit of stinging indictment. :)  Can't we play nice? But I understand the sentiment. I really was after the point that the E-350 isn't all that different from the D525/Ion2 combo. It is better in graphics but in terms of CPU it is probably the closest to SU3700. And to be fair, many applications and tasks we preform on a daily basis continue to be multi-threaded.

    I completely agree that Brazos is much better than Atom, but I don't think it's one of those automatic game changers, unless you're talking about a netbook. Now if AMD wants to completely and utterly destroy Intel in the the low-end market, I say drop the price another $50 bucks. Price per performance is where AMD historically has had an advantage. Remember X2? But right now, the company is benefiting from Intel having not released a successor to Pine Trail. For the netbook market, Brazos is great, but that isn't what is going to help AMD dominate the market. The lack of products in the mainstream mobile space is why AMD fired Dirk Meyer.

    On a side note, I'm a hardware agnostic. That's the way it should always be. I believe in competition and Brazos is delivering it. I just want AMD to bring a bigger fight to the table. They talked so much about Fusion, it's time to deliver. At the moment, I tend to cringe every time Gartner or IDC talks to me about market share.

    I think part of the disappointment is that AMD promised me an epic gunfight and I'm watching two people duke it out with peashooters. Ooo so Ion2 does 9 fps Brazos does 12 fps.

    Yes, I also think that Brazos belongs to notebooks and not normal laptops.

    It does. My understanding is that brazos is their attempt at making at an APU that can compete with the atom in the netbook or low-powered-notebook market. The future llano APUs will be desktop/laptop APUs and bulldozers are server/high end desktop CPUs.

    Good writeup. I was leaning towards the ASUS e-350 but it didn't make it into the test :(

    So everyone is in agreement? Brazos does better in a netbook. To clarify, AMD's management was a bit too ambitious. It envisioned this as a revolution in computing for thin and light notebooks, budget notebooks, and All-in-One desktops. That's how they initially positioned the product. The fact that we have a 15.6" C-50 system is an example of how crazy it's gotten. That's the agenda they're pushing. I just feel that is a bit too optimistic. Almost every week, Best Buy has a doorbuster 15.6" Phenom that's priced the same as the larger Brazos systems.

    OOO... You mean the 1215B? I would recommend that one over the dm1z. I just didn't have the time to put it through the paces.

    These CPU as far as Gaming goes completely useless cause it is unplayable. Only good side is low power usage otherwise Intel ATOM and AMD solution -> not sure why even make it.

    AMD didn't really position Brazos as a low-cost gaming platform. Therefore, I shouldn't be too surprised when it doesn't compete well in newer titles. Older titles should be its natural stomping ground.

    Essentially, I see Brazos more as a general productivity platform with good HD video capability and the ability to play older gaming titles at 720p. If it fulfils this role, then it's serving its purpose, but it should never do so for more than $500.

    Tell that to AMD. The marketing folks cite Wow and Flash/1080p video as what the Brazos should do on a day to day basis. Had they been realistic, I wouldn't be so pessimistic. The fact that there is a 15.6" E-240 proves my point. That's just nuts.

    Awfully disappointing results. I was really hoping these chips would usher in an age where all new CPU/GPU/APU systems could handle multitasking well and at least make games playable. Not so I guess.

    Yep! looks great. $450 on newegg so it's a bit steep but looks fantastic. I am probably picking it up within the next month or so just to see what other companies have to offer.

    It is an attempt, but bear in mind they just released fusion last year and these new e-350's started being sold by OEMs as HTPC combo's or netbooks just earlier this year. 30 FPS for WoW is actually great... it's an MMORPG, you don't need to be tipping >60 so you can hit that headshot. The e-350 can bitstream -- something the atom quite simply stinks at --and play at decent FPS at low/medium settings that are far more playable than what atom alone can offer and better and cheaper than an atom/ion combination.

    Forget bulldozer for a second. This fusion tech has way more potential and brings more to the table for a much larger base of consumers. If you're looking for enthusiast, 1 hour battery life 60FPS modern title games then you need look elsewhere. This product simply isn't made for nor ever advertised to do that. It's in mini-ITX format, and that alone should tell you everything you need to know.

    I don't really understand why Brazos gets 'bumped-up' in class from netbook to notebook --- and then 'panned' as insufficient. Especially when 'Llano-mobile' is being shipped to OEMs.

    And when you have to 'explain' yourself in your conclusion --- that's pretty sad.

    What? AMD disappoints again in the note/netbook market? What....But...How...
    "The NV51B-series employs two APUs: Zacate and Ontario."
    Oh, Canada. No wonder.
