    Official HD4870X2 (R700) Review Thread

    AMD Press Release
    AMD Launches World’s Fastest Graphics Card

    Sunnyvale, Calif. -- August 12, 2008 --
    AMD (NYSE: AMD) today announced the world’s fastest graphics card, the ATI Radeon™ HD 4870 X2, advancing visual computing ever closer to eye-definition computing gaming and cinematic experiences and delivering a whopping 2.4 teraFLOPS of processing power. Also announced today is the ATI Radeon™ HD 4850 X2 graphics card, delivering blistering performance at a compelling price point.

    These cards comprise the ATI Radeon HD 4800 X2 series, combining two ATI Radeon HD 4800 series GPUs with a more advanced cross-GPU connection based on the PCIe 2.0 standard, plus two gigabytes of memory – the most in any currently available consumer graphics card. These technologies combine to make the ATI Radeon HD 4800 X2 series perfectly suited for the most demanding games, able to deliver astonishing frame rates at extreme resolutions and image quality settings.

    The capabilities of the ATI Radeon HD 4800 X2 series were on display yesterday in New York City, where leading experts from the game development community and Hollywood joined AMD to discuss and demonstrate eye-definition computing computing. Eye-definition computing is the art and science of achieving visual computing experiences that seem optically real. The tremendous computational 2.4 teraFLOPS horsepower of the ATI Radeon HD 4800 X2 series makes computing experiences that approach eye-definition computing possible. The first application of eye-definition computing computing, demonstrated by AMD in New York yesterday, is Cinema 2.0, the fusion of digital people, places and things, rendered with real-time interactivity. Cinema 2.0 shows the power to digitally create interactive environments and characters that seem optically real in either a video game or digital cinema context. With the help of leading content creators, AMD demonstrated the first “virtual” actor to be rendered in real-time in perfect, lifelike detail, via the incredible processing power found in the ATI Radeon HD 4800 X2 series.

    Based on an advanced 55nm design and leading DirectX® 10.1 support, the ATI Radeon HD 4800 X2 series delivers engineering elegance and the industry’s most compelling feature set. The ATI Radeon HD 4870 X2 is immediately available from e-tailers worldwide priced at USD $549 SRP, while the ATI Radeon HD 4850 X2 is scheduled to be available in September at an estimated price of USD $399.3

    ATI Radeon HD 4870 X2: The world’s fastest graphics card
    The ATI Radeon HD 4870 X2 delivers unsurpassed graphics horsepower, setting a new performance bar for visual computing with 2.4 teraFLOPS of processing power on a single card. It is also the world’s first graphics card to include 2GB of ultra-high bandwidth GDDR5 memory. The ATI Radeon HD 4870 X2 features two GPUs based on a second generation 55nm technology and clocked at 750 MHz, with a combined 1600 stream processors.

    Engineered to be the world’s fastest graphics card, the ATI Radeon HD 4870 X2 was built with efficiency, scalability and performance in mind, delivering four times the performance efficiency AMD high-end GPU offerings released just one year ago.

    ...

    ATI Radeon HD 4850 X2: New levels of performance under $400
    Setting a new performance standard in graphics cards priced under $400, the ATI Radeon HD 4850 X2 provides the power to play today’s most demanding titles at ultra-high settings. Like its big brother, the ATI Radeon HD 4850 X2 features 1600 stream processors, and two GPUs clocked at 625 MHz. The ATI Radeon HD 4850 X2 features 2GB of GDDR3 memory.

    From Hardware Canucks, 5X faster on Min. FPS than the HD4870 :O

    Crossfire X....... Unfortunately it's also a power sucking whore in this mode, but none the less we'll look at it as well

    Whats the deal with this?,

We were informed that the feature will not be enabled until a later date, though.

    I still have to stress that for such an expensive card, you are going to want a beefy resolution. Anything lower than 1920x1200 is overkill on this card, even if you want to bump up the anti-aliasing. Sure, AA looks better, but at this price point, you might as well stick with what you have and just purchase a $300 monitor and then an HD 4870 or GTX 260, which will still handle 1920x1200 with absolute ease.

    Props to Hardware Canucks, they used a 3.9GHz Quad-core and recognised the need to pair the cards in a decent system! Some reviews have 4 GPUs on a 3GHz dual-core... it's not doing the cards the justice they seem to deserve?!

    I found the answer to my question,

    Quote Originally Posted by TechPowerUp

The XSP offers an additional 5 GB/s interlink bandwidth between the GPUs but is not enabled at this time. Yes, you read correctly. The official reason why the XSP is disabled at this time is because that much bandwidth is not required with current applications and it will be enabled at some point in the future via driver update.

    Still, it surprises me that the CF 4870 512Mb trails by a small margin. This makes me wonder why some people are waiting for the 4870 1Gb model. TPU disabled one core to give us an idea but there seems to be a few problems when they did that.

    4870 512Mb is still a great card for those with 16xx resolutions.

    my 4870 is doing fine for my 24" 1920x1200 resolution, no point in spending 600 bucks now when in 6 months a newer card will arive, 40nm. If you already have a GTX or a 4850/4870 IMO its better to wait till early next year. No new games coming out anyway. Anything that comes is a console port which even an 8800GTX should still be holding ground.

    Yep, thats mine. If anyone has any questions, I would be glad to answer them. I would love to see some feedback on the Crysis benches (or on the review in general) as well.

    Wow, this thing is a beast...

    The scalability is amazing...

    (Also, the title of the thread says 4780 X2. It should be 4870 X2!)

    Is it just me, or is no one applying high AA in Crysis? People are missing the boat here.......16xAA is playable in CRYSIS @ 1920x1200!

    I tried 4xAA/16xAF at 1920x1200 with both GTX 280 and HD4870X2... not at all as playable as hoped; while some scenes give nice FPS, when the going gets though the FPS dip well below playable. However I did not include my numbers as I hadn't finished testing all the AA in detail and had some strange numbers, either buggy drivers or buggy bencher rather than include unsure numbers I'm going to provide a followup with Crysis AA performance later on

    it really depends what scene you benchmark what the outcome will be, Techpowerup's did AA tests and included them:



    they only stated average FPS though but don't provide details on how they tested the game :/
