Efficiency Analysis: Atom D510 Vs. Atom D525/ION2

Round 3: Audio And Video Benchmarks

Audio Benchmarks

Audio benchmarks have become less important due to the abundant processing power available today for this type of workload today. However, since audio remains an important part of people's everyday computing, we thought it important to include here.

Benchmarks and Settings:

Benchmark Details
iTunesVersion: 9.0.3.15, Audio CD ("Terminator II" SE), 53 min., Convert to AAC audio format
Lame MP3Version 3.98.3, Audio CD "Terminator II SE", 53 min., Convert WAV to MP3 audio format, Command: -b 160 --nores (160 Kb/s)


As expected, the Atom D525 wins this round thanks to its higer 1.8 GHz clock speed.

Video Benchmarks

Video transcoding is one of the most demanding workloads for home and multimedia systems, and while few users will transcode high definition video on an Atom machine, these workloads are very suitable for performance testing.

Benchmarks and Settings:

Benchmark Details
HandBrake CLIVersion: 0.94, Video: Big Buck Bunny (720x480, 23.972 frames) 5 min., Audio: Dolby Digital, 48000 Hz, 6-Channel, English to Video: AVC1 Audio1: AC3 Audio2: AAC (High Profile)
MainConcept Reference v2
Version: 2.0.0.1555, MPEG-2 to H.264, MainConcept H.264/AVC Codec, 28 sec. HDTV 1920x1080 (MPEG-2), Audio:
MPEG-2 (44.1 kHz, 2-Channel, 16-Bit, 224 Kb/s), Codec: H.264 Pro, Mode: PAL 50i (25 FPS), Profile: H.264 BD HDMV


Again, we find similar results. The Atom D525 is clearly faster than the Atom D510, but it doesn't provide major benefits here.

Now it's time to look at power consumption. Does the faster Atom's additional performance come at the expense of efficiency?

    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.

    super_tycooni'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 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.
