Nvidia’s Kepler announced as GeForce GTX 680

Thursday, 22nd March 2012 14:32 GMT By Stephany Nunneley

Nvidia has announced the GeForce GTX 680, formerly known by the codeaname Kepler, which the firm is calling the “fastest GPU [and] world’s most power efficient.” It’s the same graphics card Unreal Engine’s Samaritan tech demo was running on at GDC.

Two changes, which according to the firm improve the GPU’s energy efficiency, are the new streaming multiprocessor and the “GPU Boost” which will fluctuate clock speed.

According to Shack, before Epic used the card at GDC, the Samaritan demo was running on three GTX 580 cards and needed a draw a total of 732 watts to run. However, the demo at GDC was shown using only the GTX 680 which draws only 195 watts of power.

Base clocking hits at 1006 MHz and a boosted it will clock at 1058 MHz. Nvidia promised the “GPU Boost doesn’t take away from overclocking,” and it provides users with more than “one way to overclock your GPU.”

“You can still increase the base clock just like before and the boost clock will increase correspondingly,” said Nvidia. “Alternatively, you can increase the power target. This is most useful for games that are consuming near 100% of this power target.”

The card will be available to purchase starting today and will run you around the $500 depending on the retailer.

Here’s a list of reviews for the card, with a big thanks to Talkar for compiling it for us:

    I’m not impressed at all by the specs.

    I’m only impressed by TDP and it’s nice launch price.
    Stream processors is indeed a sexy thing and Power boost too, but there are no games that will be used to it’s potential until next gen systems will arrive.

    580 GTX is enough for everything and beyond.

    @1&2 Thanks a million! I will add those when I go in to clean it up.

    Hey Erth, do you really think the GTX 580 is relatively future proof. Im looking to build a rig and gtx 580s are on sale right now at canadacomputers.com. pretty decent discounts too.

    @5 No videocard is futureproof but 580 might be quite good. I know I have a weaker 560Ti with quite some power for it’s average price and I’m really happy with it. For the record Battlefield 3 on ultra runs at 45 fps.

    @5 – I’m running a GTX 480 and its more GPU than any game really uses, so a 580 would be even better.
    However, if your going to be near the $400 to $500 range price wise, I would just wait for the 680.

    @ 7- the thing is right now you can get some great non reference 580s with amazing cooling solutions and overclocking potential for 360$
