Application Performance, Round One: PCMark 7

If the battery life was a pleasant change of pace, general application unfortunately remains a weak spot for AMD. Remember that Llano uses a tweaked K10.5 architecture for the CPU portion of the core, and while L2 cache per core is doubled relative to the previous generation quad-core Phenom parts, clock speeds and IPC (instructions per clock) still appear much lower than what Intel offers. I had hoped to see Turbo Core come into play here, which makes the comparison with Toshiba’s A660D a good starting point. That notebook has a Phenom II X4 P920 (quad-core 1.6GHz) with HD 5650M graphics, so the Llano A8-3500M has very similar specs.

Before we get to the graphs, let me make a quick note that not all laptops have been tested in all applications/games. Most of the systems have been shipped back to the manufacturer, so our newer benchmarks are going to have omissions (e.g. PCMark 7). In the gaming charts later in the review, we’ll have even more omissions, and many of the slower GPUs/IGPs will only be tested at our “low” settings.

With that out of the way, let’s start our application performance comparison with PCMark7, our only all-inclusive benchmark for laptops right now. We’ve run all of the benchmarks suites in the hopes of providing a better look at overall performance; however, outside of the “Computation” suite all of the tests have a storage element. That means any system with an SSD (like the quad-core SNB unit) will boast a massive advantage over the competition. The Computation suite also has an interesting footnote in that it supports Intel’s Quick Sync for video encoding, which again gives SNB systems a massive performance advantage. You can read more about the specific suites in PCMark 7 in their whitepaper. We’ll also have two results for Llano going forward: one for using the fGPU (6620G) and a second for using the dGPU (6630M).

PCMark 7 - Storage

And here’s our first hint that Llano may not be the homerun so many were hoping to see from AMD. All of the SNB laptops are still a healthy step up from Llano in overall PCMarks—the K53E leads by 43%, and systems with quad-core SNB are faster still. Llano might appear to at least surpass the previous generation Arrandale i5-520M in Dell’s E6410, but the storage subsystem in that laptop is a particularly slow 160GB HDD and that skews the results. Then again, the overclocked Arrandale i3-380M in the ASUS U41JF falls short of Llano, so AMD is at the very least competitive with Arrandale.

Since we’re not on a level playing field as far as storage, we won’t comment too much more here, but I do have SSD-based testing complete for four of the notebooks, and once I’ve swapped in an SSD for Llano we’ll have a follow-up article. Let’s move on to application testing round two, where we’ll look at some tests where we eliminate the storage bottleneck.

    I disagree emphatically. Having used Atom-based and E-350-based netbooks (and let's not kid ourselves, the E-350 is a netbook chip), the E-350 machines just feel snappier. I'd never buy an Atom-based computer, but I love the E-350. Reply

    Absolutely agree with Dustin... Recently bought an E-350 to replace my wife's painfully struggling Atom n455 netbook. The user experience went through the roof. My wife is happier than ever (and that's a very good thing, and a very good benchmark! :))) )

    She is a "not-professional-but-quite-demanding" user. (20-30 browser tabs, Office, and video streaming at once, Twitter with multiple accounts, and so on). She used to have a C2D T6600 + GeForce 310 (or 210 , don't exactly remember) Toshiba notebook too, but since we acquired the Brazos one, she didn't turn the old one on. Have to sell it now...

    I know, Brazos is weak if compared to anything other than Atom. But magically it manages to absolutely fill its role. Hats off to AMD on that one!

    I wouldn't describe your wife as a "quite demanding" user.
    Browser tabs don't take up CPU cycles once loaded (unless the page uses AJAX, and even then a simple http request isn't a daunting task even for a 20 year old processor) and only uses a little bit of memory.
    I'd call MS Office pretty basic computer usage .
    today video decoding is almost always hardware accelerated, so most of the work is offloaded onto the GPU (where E-350 has the upper hand).
    but I digress.

    just look at the benchmarks, there isn't much of a difference between the E-350 and a D525 (or similar) in CPU intensive tasks...
    any percieved "snappiness" on your part is down to other aspects of the system (such as HDD for instance).

    are you forgetting single-threaded results? Reply

    1 synthetic benchmark... big whoop.

    they are equal in everything else

    perhaps actually read some reviews, they all agree on one thing, the system feels much smoother for daily tasks. I am sure you don't have both or used both so have no idea what you are talking about. just launching OS or any application is enough to notice the difference. I owned a n570 so i do know. Reply

    that is subjective opinion and the only subjective opinion that matters to me is my own. You fail to realize that the perceived user experience is a product of the system as a whole and not just a single component.... Reply

    i've only gotten to run two single threaded benchmarks on the E-350, and out of those two, the bench that showed the biggest improvement over the Atom was CPUMark99, by 6% percent, over an N455 in an MSI netbook.

    Granted, i didn't get to run all four of my single-threaded benchmarks on the E350 against the N455, but i will, and soon.

    Atom N455 is single core.

    There are new and better Atoms like N550

    and, BTW, the N455 even plays 720p MKV. Who would expect any more than that out of a $250 netbook?

    But at the price of the E-350, i do expect more. And by more, i mean more than just ION level graphics that might let you send out 1080p to an external display. I want some significant CPU horsepower.
