    As we inch closer to the early-April launch of AMD's newest graphics card, the Radeon HD 4890, pictures of the said card by various AMD partners are piling up. Among all the usual reference-design cards we have seen so far, that virtually every partner is working on, we have learned that ASUS is working on something bigger. The company already has a reference-design card in the works, and another one that is set to eye the top-spot in the range of HD 4890 cards that will hit the market.

    The company is designing a non-reference design accelerator that concentrates on a superior power design, and higher clock-speeds. We do not know what the company plans to call it, whether it joins the elite MATRIX series, or a "TOP" model under its general lineup, but the odds are tilting in favour of it featuring in the MATRIX lineup, the reasons you will soon know. Pictured below is its PCB, a list of some of the most notable features follows:

    [​IMG]

    • 100% digital PWM design - something the reference PCB features too, but enhanced by a small design change by ASUS
    • The 6+2 phase power circuit is controlled by two independent VRM controller chips, the vGPU can be controlled by software, and can be set up to 1.4 V with the included software
    • An 8-pin PCI-E power input replaces one of two 6-pin inputs on the reference model. This is said to add electrical stability and increase overclocking headroom
    • ASUS added the industry's highest-quality voltage regulation thanks to the Fujitsu high-density ML capacitor, that facilitates the lowest ESR, and is best suited for digital PWM circuits (the cleanest power makes it to the GPU)
    • The GPU is expected to be clocked above 900 MHz, with the GDDR5 memory at 1000 MHz (4.00 GHz effective)
    • It will feature a non-reference high-performance cooler, which doesn't want to be pictured yet
    With this on offer, the card could be one of the more expensive ones in its series. The reference-design card is expected to be priced at US $249.99, for the know.

    And probably little to no possibility of this being air-cooled, I bet. It'd be nice, though.

    So, reference cards are not using 6+8 pin designs so far ;). This maybe the OC edition (or some variant) I read about a while back. In any case I won't be surprised with this card's performance.

    I'm thinking this is going to be the card that retires my 3870x2. I like the black PCB. :D

    If this is a Matrix series card with 1GB of memory and it has one of those awesome coolers and the voltage adjustment, then I will definitely put of getting an HD 4870 512MB Matrix for this...

    If they do add voltage adjustment I bet this card can get to 1GHz. The Matrix 4870 could get up to 890MHz which is an 18% overclock. An 18% overclock on 850Mhz is 1008Mhz.

    you might aswell keep it and drop in a second 4850.

    Actually I just sold my HIS HD4850 512MB IceQ4 Turbo on craigslist for $130. Get your stuff on craigslist/ebay now, and put at a price to sell ($115-$130) because in month or two they won't even be worth $100.

    1. nope I dont
    2. the 4870 uses 2 x 6-pin and even the much stronger GTX285 uses 2 x 6-pin

    Accoring to GPU-Z 3.3 the R790 has a die area of 282mm^2, and increase of 26mm^2 over the R770's 256mm^2

    [​IMG]

    Is it possible to get an accurate comparison using the (only known R790 die shot) from ASUS:

    [​IMG]

    and this shot of a 4850:
