Nvidia's Ion: Lending Atom Some Wings

USB Transfer And Ethernet

File Transfer Via USB

Of course, life isn’t all fun and games. One of the features of today’s chipsets—especially on netbooks, where storage space is limited—is USB management. So we measured the read and write performance of each platform by transferring a large file (3.15 GB) from an internal SATA disk (a different one from the one the OS was installed on) to an external USB disk. 

It’s an open-and-shut case: the 9400M tested a lot faster than the aging ICH7, especially on write operations. The Ion provided almost identical throughput for reading and writing (at 28.5 MB/s and 27.7 MB/s respectively), where the ICH7 showed its weakness: it dropped from 27.2 MB/s for reading to 22.3 MB/s for writing.

File Transfer Via Ethernet

Since Ion also targets the nettop sector, we wanted to test its performance with file transfers via an Ethernet network. We ran into a problem with the interface, though: we couldn’t initiate a transfer in Gigabit mode, so we had to use 100 Mbps. (It’s a shame to have to do that in 2009.) Nvidia assures us that the problem is the immaturity of the test platform and its drivers, which are still in prototype stage. We’ll give them the benefit of the doubt on that, but this will be a point to watch when the production devices start coming out.

At 100 Mbps, there were no surprises: the throughput was just about at the maximum for the interface, or approximately 11 MB/s. The 945GC performed similarly, or a little better.

    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.

    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.

    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

    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.

    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.
