Radeon HD 4670 vs. Last Year's $200 Offerings: The 3870/3850 Revisited

This is an interesting comparison. We included the 3850 in our 9500 GT article, as it was a fairly popular part that had fallen to $100. This time around we throw in the 3870 in order to see how the reduced clock speed and architectural changes impact performance. Let's take a look at the mayhem.

The 4670 really takes the 3850 to task under Crysis with medium settings. Impressively, the 4670 stays above 30 fps at 1920x1200 and does a fair job of paralleling the performance of the 3870 at about a 10fps deficit after 1280x1024.

Our Enemy Territory benchmark has everything maxed out plus a little 4x antialiasing action. At low res, the 4670 actually leads the pack here. This is quite impressive and is our first inkling that maybe our hope about AA performance will prevail. The increased ROP power of the 4670 might also have an impact here, but either way this isn't a bad showing.

Both the 3870 and 3850 lead the 4670 in Oblivion with ultra high defaults and no AA. The 4670 remains playable up through 1680x1050, which is quite nice. But nothing really interesting happens until we consider what happens when we flick on the AA switch.

With 4xAA and 16xAF enabled, the tables are turned and the 4670 jumps on top. Staying barely playable at 1680x1050 with 4xAA (we'd still recommend dropping back to 1280x1024 though), the 4670 certainly looks to be on pace for delivering mainstream hardware with usable AA for resolutions that really need it while running at high quality settings.

With Age of Conan, 1024x768 is really the highest res we can manage on the 4670 with high quality. The card performs similarly to the 3850 here.

While AoC and GRID are ruled by the 4850 and 4870, the 4670 does lag the 3800 series cards. The game is still incredibly playable at 1280x1024 and we'll have to explore AA in this game a little later on as well.

Last is a look at Crysis with high quality settings (and very high quality shaders). This is a tough benchmark and we only compared the 4670 against the 3870 here. The 4670 can't quite attain playability at 1280x1024 either. Looks like something between medium and high quality would suit the 4670 best.

    The real advantage to this card over the similarly-priced 3870 is that it doesn't require any extra power connectors. I imagine it also runs much cooler, therefore not needing a loud cooling solution.

    Are there any fanless versions of this card in the works? It seems like it would be fantastic for the casual gamer who doesn't want a screaming beast of a machine.

    is obviously wrong in the chart, should be 192mm^2 or some such (118mm^2 could be the size of rv635 maybe).

    its 146 mm. http://www.firingsquad.com/media/article_image.asp...">http://www.firingsquad.com/media/article_image.asp...

    oops I think you were talking about the 3870 in that chart...

    In case anyone else is curious, here's a rundown of current lowest prices (from Newegg, shipping not included):
    3650 $40
    2600XT GDDR4 $44
    9500GT $54
    9600 GSO $75
    3850 $75
    9600 GT $80
    3870 $90
    8800 GT $105
    4850 $150

    So, as long as 4670's slot in below $75 they should sell fairly well. If MSRP is $79, that shouldn't be a problem.

    Interestingly, it looks like they are starting to put 768MB of RAM on some 9600 GSO's. Not to interesting though, since that jacks it up to the price of an 8800GT...

    I'm looking for a low power Intel C2D motherboard. What board did you use for the power consumption tests? It says an Intel G45 in the article but neither of your test bed boards are G45 boards.

    Does it CrossFire?

    Good Card for the money.
  • derek85 - Saturday, September 13, 2008 - link

    Yes it does

    I don't care if the review is biased or not, just don't have so much time to analyze every single word or sentence and extraxt the bias towards nVidia from it... I found it useful, and the 4670 seems a very, very good card for its money - and considering the already low power consumption of the 3850, the 4670 is an instant HTPC favourite, consuming even less. By the way, I never thought of sub-100$ cards as of something more than just a IGP extension, gaming performance is by no means the decisive factor here. If it can run passively, accelerate H.264 and handle some basic graphic tasks, than it's fine for me. If you can play some games with it - you got a nice bonus.

    A few of my famlymembers and myself were looking to upgrading our PCs over the next six months so I've been keeping an eye on new hardware, especially graphic cards.

    We are only looking at budget systems and seeing the benchmarks for the 4670, especially Crysis, at that pricepoint and I was about to recommend it to my family based on the review. I re-read the article and noticed your test setup, the Q9770 alone costs almost £1000!

    I know the point of the article maybe to compare the various GPUs as fairly as possible but these aren't real world figures because I think you'd be hard pressed to find someone in the real world who will use a budget GPU with an ultra high-end CPU.

    Myself, like most sane people, would couple this GPU with an entry level Celeron, Core2 or AMD X2 CPU and these charts don't say how much real world performance I'm going to get on this card.

    While I'm not expecting to get Crysis playable on the low end I am interested in the likes of Diablo3, Starcraft2 and Dawn of War2 and am severely disappointed at the lack of RTS games in your benchmarks, especially on the mid to budget reviews as these are generally the games you'll get played on lower systems.
