Efficiency Analysis: Atom D510 Vs. Atom D525/ION2

Ringing The Bell: Conclusion

Atom D525 Comes Out Ahead

Intel's new low-power, 1.8 GHz, dual-core D525 is convincing as an advanced Atom version, but it's by no means an exciting product. This changing of the guard is happening quietly and seamlessly. Jetway offers Atom D510 and D525 solutions based on identical PCB designs, making clear that a modified motherboard revision is sufficient to support the faster processor.

Also keep in mind that the performance bump doesn't change anything regarding the Atom's overall classification. This is a low-power, low-cost solution for all application scenarios, including kiosks, ATMs, point-of-sale computers, and nettops at home or the office. Atom still can't deliver application performance for serious workloads.

Platform Comparison

The 30 W idle power consumption on the Jetway's ION2 motherboard is nothing that couldn't be achieved on a well-designed desktop system. Low-power desktop computers deliver much better efficiency, as well. But they come at considerably higher cost and therefore might not be suitable for all applications or emerging markets. Still, we have to include the ION2 solution into our conclusion, as its 3D performance is a world apart from Intel's IGP, making the Jetway Atom D525 capable enough for older DirectX 9 games.

Thanks to ION2 and the VLC player 1.1.4 it is possible to smoothly watch 1080p/i videos within the discussed power envelope. This could not be done without Nvidia's graphics unit, as even 720p video was impossible to watch on the Atom D510. Since the CPU performance difference is small, it's clear that video playback differences can be attributed only to differences in graphics support.

If you want to do anything beyond browsing the Internet, manage email, and watch basic YouTube and DVD video, you should clearly consider an Atom solution with ION2 graphics. This makes a huge difference for video/multimedia. Other than that, it's important to go for a dual-core Atom. Single-core options are only suitable for specific and very limited application scenarios. Home and office nettop PCs require an Atom dual-core for smooth operation. Intel's new Atom D525 certainly is a good step, and it evolves performance for existing system designs without increasing their power envelope.

    very nice, thank you. been wondering how fast and energy efficient the new atom is. might replace the intel d945gclf2 connected to my tv.

    Thanks... now I know that a D525 is better than the D510... I thought a higher number means that it's slower... .

    Sweet! I am always looking at atoms+ion combos for my Carputer build!

    I just skipped to the power consumption after I saw the application benches.

    I'd rather keep the D510 over a D525. Longer battery life for my simple purpose of web browsing.

    i don't think you guys even tried using the d525/ion2 system for anything beyond the benchmarks. you greatly underestimate how usable it is. my asus 1215n chugs along just fine in almost any game. obviously you wouldn't want to throw something like civ5 at it, but in reality the combo plays games better than (for the most part) any iX notebook with integrated graphics. it plays company of heroes and starcraft 2 just fine at lowered settings. i'd bet you'd be surprised how viable it is as a light gaming platform for something that uses as much power as your monitor.

    I'm using xbmc with a D510, and it plays 720p video just fine, with coreavc, it can even play a few 1080p videos

    Was this supposed to be about the Ion, or the D525? Why would you write an article with the intent to compare two processors, and put them on very different platforms?

    I didn't even read this worthless article after I saw that. It would have been interesting had the reviewers used some common sense.

    Except for power savings...why would anyone buy one of these when you can get recycled PCs for almost free? In six months they will have something a lot better anyway.

    nice article, but i feel there is still need for alot of improvements

    I don't get why intel still hasn't made the transition to 32nm for the Atoms yet. You would think these chips would have been the first to get 32nm.
