Application Performance: AMD's P520 in Perspective

We'll start with the usual suspects and look at application performance from the 5551G. With a dual-core 2.3GHz AMD processor, we expect significantly lower scores than the Intel competition, at least in applications. However, the more interesting question is going to be how the P520 compares to the quad-core P920; outside of heavily threaded benchmarks, the P520 could be the better choice.

The story isn't quite as clear as we'd like. P520 wins at PCMark05 and single-threaded Cinebench, but it places below the P920 in PCMark Vantage and all of the remaining tests. Granted, single-threaded Cinebench is actually a very good representation of how many applications feel (as well as general Windows use), and the 5551G also places ahead of the MBP13 in most of the tests—a laptop that many a Mac user has claimed is plenty fast. So the P520 is competitive with Core 2 Duo P8600—even with a 100MHz clock speed deficit, it beats the P8600 in most of the application results. The catch is that Apple provides a ton of battery life compared to the 5551G, and they do it in a far more attractive package. The other catch is that we're also not so enamored with Apple selling two-year-old hardware in a "modern" laptop when they could easily fit Core 2010 processors into the mix. For now, AMD doesn't have something clearly better—we'll need Llano and Bulldozer offerings before we see an AMD laptop CPU that can hope to go toe to toe with Intel's mobile CPUs.

    Acer notebooks are very obviously built to a price-point...they're the only company I know that'll actually ship laptops with only one speaker to save that extra dollar. I know that doesn't apply to the Timeline but there's still plenty of penny-pinching in the build.
    And it does matter since in reliability studies they don't fare all that hot compared to companies that put more effort into good build quality.

    I think it's interesting that much of the article, when talking about the laptop overall, goes on about pricepriceprice but then you want a better LCD too, and even quantify it to the opint that the pricepriceprice advantage would be washed out by a better LCD. Not that AT has as much pull as lame mainstream places like CNet, PCWorld etc but maybe if you started making it clear that better screens at a higher price is a good thing, rather than going back and forth between 'great price' and 'bad screen,' manufacturers might take note.

    I didn't think I really said much about the LCD in this review. I mention it as being average in the intro, and I have our standard LCD test page where I show how it's no better than other budget laptop LCDs, There's definitely a place for good LCDs, but honestly putting a high quality LCD into an AMD-based laptop like this is pretty pointless. If you're willing to pay $100 more for a quality LCD, you'd probably want better build quality, better battery life, and a faster CPU as well -- all of which you can find in something like the Dell XPS 15.

    When we're looking at what is essentially a pure budget build, I'm okay with the mediocre LCDs; I don't like them, but I don't expect them to increase the cost by 15 to 25% just for the display. Basically, budget notebooks costing under $650 with standard LCDs is acceptable.

    I think you're referring to the quote at the beginning, where I reference the Toshiba A660D conclusion. Keep in mind that the A665D/A660D originally cost over $800 (it's now $680 for the A665D-S6059 at Newegg), and at a price of $800 I expect a lot more. I suppose I could edit the quote, but I didn't want to do that. Hope that clarifies things a bit. :)

    The Hardware Monitor graphic is missing from page 6.

    Instead I just see: [HWMonitor]

    Fixed, thanks. I put that in as a placeholder (we add the text into the content engine and then add images) and missed replacing it. Oops.

    Acer's best AMD model seems to be the 5553 which, despite not really being a step up, does offer switchable graphics. That in itself may gift it better battery life with that anaemic 48Wh battery.

    In any case, the CPU in the 5551 is a few months old now; it would be good if you could find a laptop with a Phenom II P650 (runs at 2.8GHz and sports a 25W TDP), though it's a new model so I doubt it's readily available.

    Great job on the review, you guys cover and discuss all the aspects that I want to know about when shopping for this kind of laptop. I recently bought the TimeLineX which is almost this exact laptop but with Core 2010 CPU and a much bigger battery for $850 CA. Cures almost all of the problems with the model in the review. Very happy with my purchase and look forward to more laptops like this in the future.

    While I do agree about the love/hate relationship with the keyboard and poor LCD screen. Overall, I still think the Acer's Aspire 5551G is better buy than the 5740G I owned before. Maybe, not in the processor department, but pretty much in everything else.

    I've played around with a similar Acer laptop model at Wal-mart and the build quality feels much better than the plastic gemstone design of the 5740G. The 5740G has poor battery life, it had an annoying beep each time I unplugged the power adapter, it weighed more than other laptops in its class, the Western Digital hard drive kept freezing so I had to install quietHDD, the touchpad buttons were stiff to push down, etc. There were just too many annoying things with the 5740G. All these flaws pretty much killed my expectations of the laptop.

    Now, the TimelineX 4820TG is on a whole different level. I've had no problems with it and the build quality feels more sturdier than the 5740G that I owned before. It's given me around 6 hours of battery life. it's extremely thin, weighs only 4.65 lbs, has a Core i processor, it looks professional, it has switchable graphics, etc. and best thing is that it's only around $800. Here is my review. http://forum.notebookreview.com/acer/499204-acer-a...

    While, you may argue that the TimelineX is just a better version of the Acer laptop you just reviewed. Every little improvement changes the whole experience.

    Would love to see a Acer 3820TG-7360 (i3/HD5650/4GB/$700) review . Recently i have had good experience with acer sub-notebooks.

    Acer seems to be the only one targeting decent variety in optical drive-less (sub 4lbs) notebooks. I have an 1820tz which is awesome for what it does (essentially a netbook size/batterylife but basic laptop type power). Its great for wife/kids even work related travel. And for the price it only needs to last half as long as a 'business' laptop (to cost same amount annually).

    The 3820 ( provides excellent portability and performance. Apparently (i have not received mine yet) it delivers 8hrs of battery life and <4lbs for travel (i can carry it at a conference for full day without having to have a powerbar or wreck my shoulder) yet i can play BFBC2 at medium in my hotel room in the evening.

    PS. I think laptop makers need to really evaluate the role of optical drive in modern always connected/Saas/USB key world. Even as a gamer i rarely need optical drive (bless steam). For work i have never need optical drive as everything is installed at the start (even then many software are downloaded rather CD installed). All it does is add cost and weight.

    I just bought a timelineX 4820TG for under $790 and my only complaint would be the speakers. But at 4.5lbs and getting over 6hrs batter life, I can forgive this. The keyboard is not bad at all.
    I'm not sure why anyone would by this over the 4820TG. Plus I can overclock the video card without any problem and without any obnoxious noisy fans.
