    That low core/mem looks promising. It would be interesting to see if you can get close to 4850 with some tweaking.

    And I think I found my next video card upgrade. Have been either waiting for the 4850 to drop a bit more, or something to come out between the 4670 and 4850 to come out, and this one hits exactly where I figured it would. Nipping at the heels of the 9800gtx in a few benchies there, and at the Res that matters for me 1680x1050. This looks like something I can pair with my 3870 toxic edition till I can afford a full on 4850 or 4870. Then if I wanted to I can get rid of the 3870 and run Xfire with the 4830 and 4850.

    The charts for power consumption are totally different (show a lot more consumption, especially at idle) than the charts done for the 4670 article: http://www.anandtech.com/video/showdoc.aspx?i=3405...">http://www.anandtech.com/video/showdoc.aspx?i=3405...

    From the other article: "At idle our entire testbed (Intel G45 + Core 2 Quad Q9450) used only 67W with the Radeon HD 4670." Note that this article uses QX9770 and 790i, among other differences.

    I had no idea that different chipsets (or mobos) and cpus could result in such a dramatic difference in power consumption. I sure want my computer to consume as little as possible when I am not using it.

    Are there any other articles here about this?

    More importantly, all your previous reviews show roughly a 40+ idle and load watt difference between the 4850 and 4870, yet this review has it down to 3-4 watts at both. Was there a problem with 4870 power consumption that has now been fixed?

    And now these 4850 and 4870 numbers show a wider margin again. With a different testbed I'd expect different numbers, but the relative difference on the same testbed should be the same. These numbers are more in line with AT's other 4850/70 power numbers. The original article's numbers need to be explained.

    I believe that was one of the issues with previous Catalyst drivers: for some reason the power saving stuff wasn't working on 4870. It's good to see that finally addressed.

    Seems likely for idle numbers, but I'd be curious what power saving can be done under load.
