The GF108 Fermi lineup was announced by nVidia at the 2010 IFA in the first week of September. We already covered their announcement in a previous piece along with the details of the architecture. I happen to be the first editor at AnandTech to get hold of the actual silicon in a system, and the full responsibility of putting it through the paces fell on me. Though I happen to be more of a HTPC person, I did manage to run a few of the gaming benchmarks developed by Jarred. I have been playing around with various beta driver releases from nVidia ever since I got hold of the engineering sample, but the results presented in this piece are all obtained with MXM driver version 260.66. Before we get to the gaming performance, let us take a look at some of the synthetic benchmarks related to the GPU in the Vision 3D.

The GeForce 425M comes out with surprisingly better performance than the Mobility Radeon 5650. Though the effective memory bandwidth in the 425M (25.6 GBps) is lesser than that available in the 335M (34.1 GBps), the architectural improvements seem to have delivered very similar scores in our two synthetic benchmarks. But, do these improvements show benefits in actual gaming performance? We will see that in the next section.

Our coverage of the 400M series indicated that the number of shaders in almost all the members of the GF108 series is constant at 96. They all have a DDR3 memory interface running at 800 MHz. The processor clock is locked at 2x the graphics clock for all the models. While the default 425M graphics clock frequency is 560 MHz, we could easily overclock it to 650 MHz (435M default frequency) using the nTune program available as part of the nVidia system tools suite. The GPU is very overclocking friendly, and we were even able to ramp up the memory clocks to the rumoured GT 430 specifications without encountering any issues.

The GF108 brings the latest and greatest in PureVideo to the consumer. Based on VP4, it supports hardware accelerated decode of almost all video codecs except Real Media and the On2 codecs. We have already seen the DXVA status of a VP4 enabled device in the GeForce G210 in a previous article. The DXVA Checker report for the 425M is provided below, and there is nothing unexpected in it.

    Thanks, fixed :)

    A Seagate Barracuda Momentus XT 500GB would do much better job than WD Scorpio Black.

    A Seagate Momentus XT 500GB would cost nearly twice as much as the WD Scorpio Black 500GB ($130 vs $75 at retail), and the performance difference is rather unimpressive. In the tests where the Seagate can make use of its SLC cache it can take the lead, but in most tests the Scorpio Black is faster, especially when seek times or write performance come into play, since those are Seagate's major weaknesses.

    Cool box but LOL at the THX logo being slapped on it. They used to put that on heavily compressed DVD mixes, not all of them good either. Consumers don't care anymore.

    Personally, I don't care too much about the THX either :) If you are using HDMI for audio, it doesn't even appear in the picture.

    The internal audio codec is advertised with THX, so the HTPC using it gets the additional marketing point too :)

    you guys did such an excellent job with this review! thanks for all the hard work and effort you guys put in!

    I'm not seeing the value here. A thousand dollars to stream content, and play blurays? One of the previous replies you stated that there was no native bluray support for the mac mini, true. And there is for a machine running windows? Tacking on Cyberlink is not native support.

    That is way too much hardware for what it does, which illustrates how badly Windows is for a platform. You could do much better with less hardware. Which is the real problem with a htpc, the software, the operating system, and various codecs, and getting it to all work together. Too much complexity. Most of the processor is wasted on layers of software instead of doing actual work. Most of the effort is expended to compensate for lazy and inadequate programming, as well as DRM.

    I understand the concept, I had a htpc for a couple of years, but after the frustration of trying to get surround sound to work in Cyberlink for Blurays, and the tech support to keep Windows working, I gave up. In fact it was specifically windows deciding to rebuild my music library from scratch every time I opened media center to play music. I want an appliance on the other end of the remote, having to search forums and break out a mouse and keyboard to trouble shoot something that worked the day before just fine should not be step two after pressing the power button.

    In the the article, there is no details as to how much or little work it took to make the software environment to work. Did settings hold, did you have to do reconfigurations, update drivers, load codecs? I seriously doubt it worked out of the box. Working out of the box is the great failure of the pc industry. On the video quality you are hedging, saying that video quality will get better with driver updates? So it's not finished eh? That's the sad reality with the computer industry in general, nothing ships as a finished product.

    The only thing this device seems to offer are endless possibilities to reward owners with a sense of accomplishment having solved issues preventing operations promised by the vendor. You can buy a nice bluray player, wd live, and still have 700 dollars for something else.

    The real news is if you took it out of the box, plugged everything in, did a setup once, and spent the rest of the time using it. No drivers, patches, settings that reset themselves, or promises of a future update for something to work So what did it take to make it work like it's supposed to, what issues does it have? Did you listen to two channel, or full surround? How many error messages did you have to deal with?

    What you are looking for is a player like the upcoming Netgear NTV550. That would put it in the media streamer section. That would be like $700 cheaper than the Vision 3D, but, with the NTV choice, you are at the mercy of Netgear for firmware updates in case something you want doesn't work, and it also doesn't support 3D -- which is what this product is targeted towards.. For the Vision 3D running Windows, you have a number of open source developers who can enable core features like HD audio bitstreaming etc. -- Try getting open source devs to get those sort of features working on a SoC based device.

    The fact with the HTPC scene is that you do have to do some setup of sorts and deal with error messages and what no. However, sometimes, slapping on the latest XBMC build solves most problems. Our test suite is designed to give problems to various softwares, so deriding drivers / softwares on the basis of the difficulty in getting it to work is not the purpose of the review.

    Everything you state is true but, unfortunately, that can be said of computers in general. It's not limited to HTPC.

    You're also missing one of the major points of the HTPC: Its ability as a computer.
    You don't get that from a standalone device.

    You don't specify what version of MCE you were using, but if you weren't using the Windows 7 version it's not really a valid arguement.
    I never tried the Vista version, but the Win 7 version has certainly come a looong way from the XP version.
    And if you happen to be someone on a budget that wants to do it all with a single device, the price of the ASRock system is pretty attractive, even after adding the cost of the OS, monitor and BD software.

    Pretty sure the hybrid Seagate Momentus XT is the fastest 2.5" drive they could have chosen. To all the other people talking about this egregious error, WD and Seagate are the only mechanical disk hard drive manufacturer's even worth looking at.
