Radeon HD 4870 X2: Four Cards Compared

Crysis v1.21 Very High Quality

Even with very high image quality settings, the power of the overclocked quad-core CPU is nicely transferred into 3D performance. The GeForce 9800 GX2 without anti-aliasing cannot be slowed down, but with activated anti-aliasing, the frame rate starts dropping significantly at 1680x1050 because of the 2 x512 MB graphics memory. The GeForce 9800 GTX+ 512 also shows obvious memory problems at a resolution of 1920x1200 with AA turned on.

With the AMD cards, you can also see a difference between 512 MB and 1 GB of graphics memory. The Radeon HD 4870 in CrossFire shows 6 fps lower performance at 1920x1200 with anti-aliasing than the better-equipped Radeon HD 4870 X2, which has 2 x 1 GB. The Radeon HD 4850 reaches its limit at 1920x1200 with anti-aliasing and overclocking the quad-core CPU (QX@3.67) provides no improvement.

Driver Comparison: Catalyst 8.9 Versus Catalyst 8.10 w/ Radeon HD 4870 X2

In the very high quality setting mode, the results are also within measurement error limits. This is somewhat unusual; Crysis usually shows more variation when using new drivers given that it’s a very graphics-heavy game.

    "Because of accessories and price, Sapphire is our best-buy recommendation."
    One slight warning about sapphire though. If you have problems, don't expect their support team to help you before you've solved the problem yourself!

    I made a ticket regarding some issues with my 4870 on august 7th, and received a reply on the 26th of september! That's 46 days to address an error they simply stated would go away with a bios upgrade from their homepage!

    As for the article, I actually liked the detailed driver errors they encountered. Not that I liked the errors themselves, but I liked them being explained. Usually you just read 'after spending some hours resolving driver errors ....' without getting any wiser.

    Wow, AMD cards consume power like a Detroit SUV. I like Nvidia GTX 2xx series’ Toyota Prius like efficiency at idle.

    Why didnt they use the GTX260 Core 216? its like way better than the regular GTX260. And i just read yesterday that Nvidia was only going to make GTX260 Core 216 now. http://www.fudzilla.com/index.php?option=com_content&task=view&id=10497&Itemid=1

    Why didn't they try using core i7 (extreme maybe)

    Hmm your right. Power house vs crippled mouse.. yeah your analagy sucked im sure mine did to but all i saw from what you typed was i like weak stuff dont give me more power.

    seems to me if you are going to be comparing the highest end cards and even crossfire them for 4x you would have the highest resolution as one of the options. i would think people considering going x2 in crossfire would consider a 30" screen.

    don't get me wrong, i liked the article but would have liked to have seen the resolution spectrum hit the top.
  • It's nice to see the 9800GX2 included in the tests. I was considering the 4870x2 due to all the rave reviews but they never had the comparison like this against my current 9800GX2. I won't be getting new card anytime soon it seems. Thanks.
