Meet Kepler

First off, a bit of background about Nvidia’s Kepler for those who may be living under a rock and unfamiliar. As we first saw with the original GTX 680 launch, and then again with the GTX 670 AND GTX 660 Ti, Kepler is a significant improvement in hardware technology, performance, features, and software from previous GeForce generation cards. As we’ll explore during the course of this review in further detail, these improvements are quite innovative, and really move the gaming world forward.

Built upon a revised GK104, a bit different than what we saw in the previous Kepler cards, the GeForce 660 sits a couple rungs lower on the performance ladder, with slightly lower performance and a much more affordable price tag.

In terms of particulars, the GTX 660 comes with 960 CUDA cores, whereas the 660 Ti had 1344. The memory runs at 192 Bit here, same as the 660 Ti, and the 2GB of GDDR5 memory runs at 1502MHz, again the same as the GTX 660 Ti. Despite some similar specs, we don’t expect the new 660 to run with the big dogs, mostly due to the cores, and the intended competition would be AMD’s Radeon 7850 and 7870 cards.

As for clock speeds, the Gigabyte GTX 660 Windforce comes with a 1033MHz Base Clock (core) and 1502MHz memory. The GPU Boost clock on this particular Gigabyte card is 1098MHz, but this is the minimum you can expect to achieve. As you’ll see in our Overclocking section part of this review, there is more left in the tank. Needless to say, that’s a great boost (or “overclock”) out of the box here.

Here’s an image that shows a bit more detail on the particulars:

Kepler certainly brings performance improvements, but the 28nm manufacturing process also reduces heat output. However, perhaps the most significant improvement is that Kepler brings twice the Performance Per Watt when compared to Fermi. “Awesome” might be considered an understatement in that context. Lower power consumption appears to be a hallmark of Kepler, and that’s particularly encouraging.

Let’s talk next about a groundbreaking new technology on Kepler cards: GPU Boost.

    You didn’t even mention the version of nvidia drivers that were used for this test.
    the latest 306.02 Nvidia drivers are way superior to the 296.10 WHQL drivers that were prolly used with this test.

    Actually, the latest drivers are always used for our tests. On occasion, we have to use Beta drivers since the cards aren’t officially launched and therefore not supported by current “publicly available” drivers. In those instances, however, we receive drivers directly from Nvidia for testing. We don’t use old drivers, nor can we use future drivers that may have optimization tweaks; we can only use the most current ones available at the time of review.
