Today's comparison includes one of the largest collections of graphics cards we've ever put into a single piece. Between the general benchmarks and the added CrossFire/SLI numbers, we've included two Radeon HD 6970s, two Radeon HD 6950s, two Radeon HD 6870s, two Radeon HD 6850s, a Radeon HD 5970, a Radeon HD 5870, two GeForce GTX 580s, a GeForce GTX 480, two GeForce GTX 570s, a GeForce GTX 470, and two GeForce GTX 460s. By my count, that's more than 47 billion transistors worth of graphics hardware on the test bench.

Much of this is the result of reader feedback, both in the comments sections of my stories, which I monitor as often as time permits, and on Twitter, which I'm able to check more regularly. Keep that feedback coming. Two notable take-aways from the last time around: I've added the GeForce GTX 460s for reference, and I've included more extensive CrossFire/SLI testing with scaling analysis.

That's more than 47 billion transistors worth of GPU.

    Thanks for the review Angelini, these new naming schemes are hurting my head, sometimes the only way to tell (at a quick glance) which AMD card matches up to what Nvidia card, is by comparing the prices, which I think is bad for the average consumer.

    These cards are to GTX 500 series what 4000 series was to GTX 200. Not the fastest at their time but offer killer performance and feature set for the price. I too expected 6900 to be close to GTX 580, but it didn't turn out that way. Still, it is the card I have waited for to upgrade. Right in my budget.

    imagine when this hits 32nm?

    AMD's top card is about a draw with the gtx 570.
    Pricing is in line.
    Gives AMD only hold outs buying options, Nvidia already offered
    Merry Christmas

    Why drop the 580 when it comes to the multi-gpu scaling??

    Sorry all i read was this
    "This helps catch AMD up to Nvidia. However, Intel has something waiting in the wings that’ll take both graphics companies by surprise. In a couple of weeks, we'll be able to tell you more." and now i'm fixated to weather or not intel's gpu's can actually commit to proper playback.

    but from what i read at hardocp, though it is priced alongside the 570, 6970 was benched against the 580 and they were trading blows... So toms has it at par with 570 but hard has it on par with 580.. now im confused because if it can give 580 perfomance or almost 580 performance at 570 price and power then this one is a winner. Sim a 6950 was trading blows with 570 there. So i am very confused

    This is hilarious... How long ago was it that there were ATI fanboys blabbering "The 6970 is gonna be 80% faster than the GTX 580!!!". And then reality hit...
