Atom Benchmarked: 4W Of Performance

Results: Atom Is Not Suitable As An Office PC

It is quite clear that the 945GTC-D board from ECS with the Intel Atom 230 processor is not suitable for use as a desktop workstation. Although the integrated graphics core would be sufficient, the speed of the Atom 230 processor is just too slow for day-to-day desktop tasks.

Of course, not every user will agree. If you know the precise utilization of the system and you have enough experience to assess what level of computer performance is required, you may find that this system meets your needs perfectly. But this only applies to certain special types of use.

For example, it is possible to surf quite happily as long as the right operating system is used (Windows XP or Linux). If you run more than one application at a time, though, the Atom system will slow down.

The power consumption of the Atom board in both idle mode and under full load set new records in our Munich test lab. The minor advantage over other platforms is a bit disappointing, though. An AMD Sempron LE-1100 system only requires 3 watts more energy in idle mode. On the other hand, under full load, the Atom only jumps by a few watts, while the other desktop-tuned processors consume far more energy.

Anyone who tends to have a system that mainly sits idle will not notice a major difference between the energy consumption of the Atom and the Sempron LE-1100 system. This is, for example, the case when a computer is mainly used for downloads.

The desktop version of the chipset used is largely to blame for this. Since the Diamondville-based Atom system for the desktop is only currently available with an energy-hungry desktop chipset, much of the advantage of the very low energy consumption of the Atom 230 goes to waste. Maybe a motherboard manufacturer will take the plunge and build a Diamondville board based on a mobile chip set.

The dual memory interface doesn’t provide much performance advantage, either. The idea from Intel to integrate Hyper-Threading was absolutely right, as it allows the Atom to improve its performance in our tests by up to 37%. But the Atom has lower computing power compared to the current AMD and Intel platforms. We’d recommend checking out one of those before toying with an Atom-based desktop.

  • Where's Linux tests?.
  • This saved me time researching for an assignment :)
  • Shouldn't it be on 9 - cooling and temperatures,be idle and load,instead of idle and idle? >.
  • When you look at the power consumption on load and compare it to the slowness of the chip while performing on load, it becomes clear why it only uses 4 watts more...
  • A CPU without a platform is useless.
    Analyzing the Atom platform quickly from the power/performance perspective.
    CPU name / idle W / load W/ Lame (seconds) / total Lame W used
    Atom 230 / 40.5 W / 44.2 W / 773 s / 9.49 W
    Celeron 220 / 44.9 W / 55.4 W / 375 s / 5.77 W
    E2140 / 58.5 W / 69.5 W / 271 s / 5.23 W

    Clearly the Atom platform is the most inefficient power/performance wise.
    At idle you might win some W, but as soon as you try to do something you spend more power and waste more time.
    There are other things you should consider, the frustration of having to wait for things that now we are used to do near instant and the inability to play HD video or use any significant graphics.

    The only thing positive for atom is it's price. It's cheap. And maybe with a new chipset it might even be power efficient. But for now it's just cheap.
  • I wonder if it'd be able to play games if one were to equip it with a pci based 2400pro & 4gb of memory?
    Also, I wouldn't be surprised if someone invents a voltmod for those boards, so they can increase voltage for cpu, mch & ich enabling 2ghz+ speeds
  • so in other words atom is pretty much a failure unless it's pumped into a tablet or umpc? and even then apparently isn't cost effective or readily available, nice...sounds like a great product launch.
  • I ran a google search for ECS 945GCT-D mainboard, and could not find it.
    I don't get it, why do you publish tests with products that don't even exist on the vendor web site?

    Thank you, anyway
  • Raiden, while your numbers are true, I think a fairer comparison would be to use 773s for all processors (meaning the rest go to idle alot quicker). I suppose you can power your computer down afterwards or start up a web browser etc.

    Atom 230 (773s load / 0s idle) : 9.5W
    Celeron 220 (375s load / 398s idle): 10.7W
    E2140 (271s load / 502s idle): 13.4W
    Sempron LE-1100 (43.9W idle, 70.4W load, 301s load / 472s idle): 11.6W

    Sure this is biased against the Atom (not going idle at all) but with 4W delta between load and idle, I am too lazy to change the numbers already used.

    I find it comparing the Atom to a Sempron LE-1100 more and Celeron 220 interesting:

    "A Celeron at 1.20 GHz is 35% faster than an Atom at 1.60 GHz, but the Atom only consumes a fraction of the energy used by the Celeron. The AMD Sempron system, which uses almost the same energy in idle mode as the Atom system, is 43% faster."
  • in anyway, despite of the low power and low performance, i still think it'll also be good as simple file server or home server besides as umpc. for experts, it'll be enough for some robotics and control application. just like the one used for Aiko in
  • I've seen several articles on the Atom, but I have yet to see Tom's actually do a product comparison with a true Mini-ITX competitor, like Via. Is this because Via won't provide the hardware?
  • It would be interesting to see how to reduce power use by the 945GC when in a "headless" system e.g. firewall. I'd love to see how well this board performs with Endian Firewall or PFsense. Especially with all the Unified Threat Management (UTM) features running.
  • What about VIA's EPIA series? They have been around for ages and utilise less power than this, plus they have DVD and HD acceleration onboard. They are frequently run in cars and off batteries so they must have pretty low power requirements. They even released a dual-core one a while ago, surely this would kick atom's butt? (the DP-310 which has been out for years now).
    Why not compare this like-for-like, surely you are aware of the VIA platforms and they are widely available with speeds up to 2GHz now. What's more VIA have announced that they will be providing boards with PCI-E x16 for proper graphics cards, giving them the edge over Atom which has been crippled to stop it affecting sales of Intel's more powerful and expensive products.

    All this coverage of Atom would be far more balanced journalism if you compared it to a contender in it's own arena rather than more fully-featured desktop boards intended for a different market. I'd suggest you look at some of the Jetway boards for instance.

  • Please elaborate on this:
    Working with a screen resolution of 1280x1024 is possible, but compared to a traditional graphics card, it is a little blurred. At 1920x1200, the screen is washed-out and it is no longer practical to try to use on a daily basis.
    I use a VGA connection to a 1920x1200 LCD panel all day long (through a KVM switch, no-less). It doesn't look washed out and it is completely usable on a daily basis. And how would an LCD panel look "blurred"? The pixels don't move, don't shift, and don't require focus? Are you using a CRT, and that is exhibiting timing issues with the VGA output that are not visible with a higher-quality VGA output driver chip? I just can't make sense out of your statements about video output.
  • Why isn't it compared to the mini-ITX offerings from VIA. Comparing it to full powered desktops is like comparing a bicycle to a motorcycle.
  • Seems like it's performance is comparable to an Athlon XP 2400 or so. I don't see how that's not acceptable for office use. Our whole site had PIIIs running XP up until 2005.
  • I don't understand why Intel chose to have an elongated rectangular shaped die. Common sense dictates that the die be as square shaped as possible to minimize the surface area to pack more dies per wafer.
  • I know that these Taiwanese manufacturers have enthusiastically popped the Atom into these boards - but pitting a CPU designed to go after Transmeta, ARM, AMD Geode and VIA C7 type processors was aptly put as "pitting a bicycle against a motorcycle." This processor simply wasn't designed to compete in the desktop segment.
  • tennisballg: "Seems like it's performance is comparable to an Athlon XP 2400 or so. I don't see how that's not acceptable for office use. Our whole site had PIIIs running XP up until 2005."

    Surely not Athlon XP 2400, but something twice slower, like Pentium 4 1,4GHz, or an Athlon 1 GHz. And same as Celeron M at 900Mhz which is used in EEE PC subnotebooks.
