Sapphire Announces Radeon HD7790 OC Edition

Sapphire is releasing another 7790 graphics card, but this time one with a factory overclock as well as twice the amount of onboard memory. Previously, AMD had asked manufacturers not to overclock the 7790 chip to prevent the card from outperforming the slightly higher priced 7850.

Sapphire's new HD 7790 OC carries 2 GB of onboard GDDR5 memory that runs at a clock speed of 6.40 GHz over a 128-bit memory bus. The GPU's clock speed has been increased by five percent, boosting it up to 1,050 MHz, 50 MHz over the reference 1,000 MHz. Connectivity is taken care of by two DVI ports, a single HDMI port as well as a DisplayPort.

The cooler on the graphics card is one that has been used before; in fact, it's the cooler that is used on the regular HD 7790 that Sapphire sells. The cooler is built using an aluminum block through which heat is transferred to two copper heatpipes. Beyond this, the cooler comes with a backplate to ensure that the memory and VRMs also remain cooled up to 13°C lower than without a backplate.

So far there has been no word on pricing or availability.

    I would like to see how closely this performs to the 7850

    The 128-bit memory bus was a poor decision by AMD.

    I love how this card has a backplate while the Sapphire 7970, which is 3x the price doesnt.

    The bus width was a decision made with future designs in mind.
    This card can come down in price and be very competitive, should nVidia come in with something close to it..
    It does the job, the memory speeds sees to that

    The Vapor-X is a custom PCB though which is a major benefit and has a much superior cooling solution while also using superior components (Caps, VRMs and chokes).

    But the memory is still only 6GHz vs this ones 6.4GHz. Still the Vapor-X has had good OCing in reviews so its not a big deal.

    So since AMD is slow to release new chips they release the 7790, so the 7850 doesn't drop down to the ~140-150 price range. Hmmm.....what a way to delay the inevitable...

    This card reminds me of my old XFX HD 5750. Seems like it might be a really great bang for the buck now or an even better deal when the HD 8000 line comes out.

    Depending on the price I'd be wanting to spend the extra $10-20 more for the 7850, if that is where this price comes in at.

    The standard 1GB 7790 MSI card has already been down to $110 AR. The regular version of the 7790 should be priced around $120-125 and 2GB version around $145-150 with the 7770 needs to drop down to $100-105 and 7750 to $75-80(the 7750 and 7770 already frequently found at these prices after rebate).

    Yeah $130-140 is a fair price for the 7790 (before any rebates), but if it get too much closer to $150-160 than the 7850 is a better buy, IMHO.
