Intel's Atom D525 offers a faster clock rate than its predecessor at the same 13 W TDP. Obviously, the new dual-core chip is going to be faster. But after we determined that the Core i3 is more efficient, can Atom D525 usurp the desktop contender?
Intel recently added a faster Atom dual-core model to its lineup. The Atom D525 overtakes its predecessor, the D510, thanks to a 1.8 GHz clock speed (as opposed to the D510's 1.66 GHz).
But this isn't the only change. Both new Atom models, the dual-core D525 and single-core D425, support up to 4 GB of DDR3-800 memory. The chips still employ Hyper-Threading and come with the Pineview core’s integrated graphics unit. Finally, the 512 KB L2 cache per core remains unchanged.
As a quick bit of clarification, while the Atom N-series is designed for netbooks, the D family usually goes into nettops.
We tested Jetway's NC98-525-LF integrated motherboard, a fully-featured mini-ITX platform with an Atom D525. Jetway adds an Nvidia ION2 for additional graphics horsepower. This might not be important for 3D applications due to the chipset's inadequate performance capabilities for this demanding segment, but ION2 helps to smooth video playback at resolutions up to 1080p.
Despite its modest 1.8 GHz clock speed, even the fastest Atom D525 is still much slower than any desktop processor, even the relatively poky Intel Celeron. Desktop chips are much faster per clock, but Atom is hard to beat when it comes to power consumption. Atom allows manufacturers to create low-power systems.
But low power doesn't always translate into high efficiency. The article Efficiency Analysis: Core i3 Trumps Atom On The Desktop provides a great insight into performance per watt, comparing an entry-level Core i3 processor and the Atom D510 dual-core. Now it's time to see how much better the Atom D525 actually is.
This duel compares the Atom D510 against the Atom D525 in synthetic benchmarks, application benchmarks, and our power consumption and efficiency test suite. Let's see what the new Atom dual-core can do versus the model that came before.

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.
>>This could not be done without Nvidia's graphics unit, as even 720p video was impossible to watch on the Atom D510.
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.
I feel the article lacked meat. It would have been interesting to compare it to an old gf9300 or even gf7050 socket 775 motherboard with a PDC or even CDC. The latter options would probably cost as much nowadays as the d525+ion combo.
Oh come on, how is it NOT possible to watch a 720 p on an atom, if I can watch it with an sempron 2400+ which is just ancient.
sweet!!!
I have a mini ITX buil but its a gigabyte pushing an 1156LGA i5 overclocked to 4.16GHz and DDR3 1333 ram!!! nice for HTPC with a GTS 250 Nvidia grafix card too .....
In general without the video/power tests the rest are still fairly valid for a performance comparison.

Cool, I got one of those too but with a 5770, what does it have to do with this article? 46 watts idle without overclocking is cool though.
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.
Way less then my monitor, i bet i have the least efficient screen ever made.
Here is my personal experience as a student, with my 11.6" HP MINI 311 ION w/ 3GB and Windows 7 Pro 32bit with Full AERO features active:
I can run Mathlab, have 7 browsers open, and OpenOffice.org all at the same time. Oh yes, i can play Youtube HD 1080 smooth unlike most of the laptops out there. So to me, its the most amazing device that is light, cheap and can pack a lot of punch for 400 bux canadian.
I just wait for Zapate.
I kind of think some things are bull;
The older Atom N260 was capable of playing back older DX9 games,and HD 720p video; why should the desktop version not be able to?
Perhaps not at 1600x1200 pixels or more, but at 1024x600 or 720p it should play back most games on lowered resolution!
really? i never knew more clockspeed results in better performance and more power consumption, and relatively the same efficiency. sorry this just wasnt a good read
Are you sure that old D510MO doesn't have a mini-PCIe slot, whats that grey riser between the ATX power plug and the PCI slot? Still, you can see why Intel downplays ION, it adds a lot to the power consumption. Sure, it makes it much more capable at video and gaming, but others here seem to think the non-ION variety can handle 720P just fine, which would put these in league with the AppleTV, where they cannot compete on price. I just don't see where Atom fits into any market segment. ARM is much more power efficient, and The Core i3s and Athlon II's are much too powerful (and not really much more expensive).
I own two Atom-based systems (one being a D510) and I have to say, they are pretty darn amazing for the cost to operate. It's nice to see this tech advance, and I would love to see continued advancement in power efficiency and see those power levels continue to drop.
