Nvidia's Ion: Lending Atom Some Wings

So, What About Intel?

The Intel D945GCLF uses a more classic design

In order to evaluate the wisdom of matching a chipset like the 9400M with a processor as… well, “mobile” as the Atom, we compared it with the only competing platform on the market: the Intel reference platform.

To accomplish this, we dug out our D945GCLF motherboard. It is also compact, being a mini-ITX format board. But next to the Ion, it starts looking huge. Its design is much more classic—there’s no daughterboard connected via PCI Express, and everything is on the same PCB. What’s “everything”? An Atom 230 processor (the same as in the Ion), an Intel 945GC chipset, the ICH7 southbridge, and a few ports and extension slots.

VGA, serial, parallel, and PS/2 ports... Welcome to the past!

One of the interesting differences between the platforms is their cooling systems. There’s a minuscule passive heatsink on the CPU, but a there’s a large heatsink (with a fan) on the chipset. This is the first sign that something’s not quite right with the chipset, but we’ll come back to that later.

Next to these three main ICs is a standard DDR2 DIMM slot (maximum 2 GB), but also two internal SATA ports, one IDE connector, one PCI slot, a parallel port, a serial port (yep, you heard right), a VGA port, two PS/2 ports, three analog audio jacks, a 100 Mbps Ethernet port, and four USB 2.0 ports. There are also connectors on the card for two additional USB ports.

So the Intel reference board is no slouch. But its connectivity shows the age of its supporting core logic—instead of eSATA and HDMI, you get VGA and serial connectivity.

    Let's be clear - the Ion reference platform is for a nettop - not a netbook. Its based on the dual core Atom 330. I doubt very much that Ion with a single code Atom 230 or N270 would have enough horsepower to do the BD decryption required for BD playback.
  • matthieu lamelot
    Please, let me be clear : the platform reviewed was equipped with an Atom 230, not a 330, as is perfectly obvious from the pictures (one single die on the CPU package).
    And, yes, it's powerful enough (thanks to the 9400M) to smoothly playback a BD like Casino Royale (including the HDCP decryption). CPU utilization rose to around 67 % during that test.
    And even though the Ion ref platform is kind of a nettop (and we tested it with that in mind, comparing it to Intel's nettop platform), it could also fit in a netbook since 9400M TDP is very close to that of Intel 945GSE chipset that is found in most netbooks today : 12 W compared to 9,3 W. Nvidia and its partners would just need to drop 9400M's frequency a bit.

    Matthieu, I'm not sure who makes the onboard sound, but if it's Realtek you need to have Stereo Mix enabled for CoD 4 to run. Also, I found that I couldn't start CoD4 (with what appears to be the same error even though I can't really understand it) without plugging in speakers. Yes, speakers. Although any output device might have sufficed.

    Realtek codecs are quite common (thus I concur with randomizer); some are quite advanced in that they do automatic detection of what kind of hardware is connected to what pin (through best guess from device impedance, considering the low dB noise those codecs output they are some precise piece of ingineering), allowing autodetection of the sound setup (they will detect if you replace a microphone with a set of speakers, and switch configuration from stereo+microphone to 4.0 audio, for example; that requires driver support though).
    If CoD4 requires sound (some games are funny this way) and no hardware is plugged in, then the sound card may report a status CoD4 wasn't expecting, and refuse to run.
  • randomizer
    Well you'd think that they would have patched the game so that it doesn't have problems with needing Stereo Mix and output devices by now. What if my speakers are dead? That's just poor...

    I immediately looked at the benchmark images, instead of reading the accompanying text around it, and I thought "WTH is AMD (green bar) doing on the nVidia ION platform." I thought I was linked to another page of another review.
  • hei man pls ...for now nvidia platform has some advantages but with DX11 you will not need gpu any more ...so for now it's ok for future this platform will be nothing but dust
  • nukemaster
    You may not need a GPU, but a GPU is still far faster then the cpu at running games.

    Good review its about time Atom got a little help.
  • liemfukliang
    I wont buy atom until it can run PCMark Vantage, 3DMark Vantage. I don't mean it has to be high score, I just one it is finish the test and not error. :)

    I'd like to be able to buy one of those little reference systems. It would make a nice little HTPC.
