Power Consumption

As expected, NVIDIA's GeForce 9300 power consumption is competitive with G45. Gaming power consumption is particularly impressive; NVIDIA delivers better performance and lower power consumption than G45. We provided results with both Cool'n'Quiet enabled and disabled for the AMD platforms given the issues we mentioned in our last article.

    Nice LL Cool J reference in the article description! Reply

    Hey guys,

    Great to see the articles are up. A couple of quick questions and a comment.

    Could you mention clearly what nvidia driver versions (both graphics and HDMI) you used for the tests?

    Also, you seem to hint that 5.1 audio is an option with this newest driver set from nvidia. Is this indeed the case?

    Also, to echo the comments of some others, it would be nice to see the blu ray playback numbers with cheaper cpus. I have seen the Athlon X2 BE (2.3 ghz) going for less than $40, and even a 3 ghz X2 for $75 or so, which would certainly make buying a cheap discrete graphics card a viable option cost-wise.

    >>Unfortunately, as we've mentioned before, there is no support for bitstreaming Dolby TrueHD or DTS-HD MA; you'll need to wait until sometime next year before you get full support there.

    Hmm - does that mean the hardware is there in THIS chipset but we nned to wait for driver/bios updates!?!?!?!? Or are we talking about a new chipset?

    Sorry for the confusion, absolutely none of the current chipsets (G45, 780G, GF8200, GF9300) support or will support bitstreaming TrueHD/DTS-HD MA. Next year we will see the first GPUs with actual support for this.

    8-channel LPCM is the best you'll get for now.

    Isn't LPCM the best you can get anyway? Your Blu-ray decoder (Eg. PowerDVD, standalone Blu-ray player) decodes the audio stream (the best available) and sends that audio to your stereo via PCM. Some Blu-rays even have the LPCM stream raw on the disc. Why would you ever want/care about TrueHD/DTS-HD MA streaming when you are already getting perfect, lossless 7.1 audio to your speakers?

    Hybrd power was one of the more compelling features of this chipset for HTPC use - I want my box sipping as little juice as possible untile game time. Unfortunately, all the reviews I've read so far and this Nvidia page:
    http://www.nvidia.com/object/hybrid_sli_desktop.ht...">http://www.nvidia.com/object/hybrid_sli_desktop.ht...
    seem to indicate Hybrid Power is NOT a feature of the new chipset. I read the comment earlier about it being up to board manufacturers to implement but the page linked above seems to indicate the chipset itself lacks support. Can you guys please confirm?

    I've been holding off buying my new rig for 3 months just for this feature. I'm on 100% solar power and although I can still run my current rig that draws more power than a newer one will, any savings I can make are worthwhile (and give me more scope elsewhere).

    All the reading I did months ago suggested this chipset would deliver Hybrid Power with Intel CPU. What's the official word on this? If, as the nvidia page linked suggests, this chipset does not deliver this, what's next? When do we get it?

    I'm not the brightest crayon on the box when it comes to tech but couldn't a company just solder on a decent chip and forget this whole IGP nonsense? Like take an Nvidia 9500 or 9600 chip and solder it right on to the board along with 128MB DDR RAM. You'd have you're reasonable gaming performance without suffering through the 9300 which looks to be nothing extraordinary. Couldn't they cool it with standard HSF?

    Seems to be a lot of effort for little reward.

    There would be little room for it, unless you gave up say two slots. Chaintech did this years ago, cool motherboard, but ran very hot. Suffice to say, no one bothers with it anymore. You might as well just add the memory like side port but a seperate chipset and graphics chip? Only works well in laptops. Reply

    You're not saving so much money over a discrete video card (you still need everything a video card have), and you can't "upgrade" (yes, you can add another video card and disable the onboard one, but you can't have your cake and eat it too).
