Kepler: The Return
First off, a bit of background about Nvidia’s Kepler and current lineup releases for those who may be living under a rock and unfamiliar.
When Nvidia’s Kepler GTX GeForce 680 launched amidst much hype and fanfare, it was a revolutionary step forward from the days of Fermi. The changes and advances were significant in just about every facet, and the popularity of Kepler is a testament to its own success. So where to go from there? Moving forward, the 700 series is the next natural step for Nvidia, but the advances are more modest; it’s now evolutionary, a stepping stone ahead, and not quite the giant leap we saw when Kepler launched.
So, how did we get here? After the 600 series lineup had matured, we saw the launch of Nvidia’s GTX Titan. Turns out that Titan was the answer to our collective and confused “Why?” as far as Nvidia’s product lineup goes, but it seems we didn’t know it at the time. In hindsight, it now makes sense because the GeForce GTX 780 appears to be more of an improvement and refinement of Titan, not the GTX 680.
The actual Kepler core GK104 architecture on the GeForce GTX 780 actually isn’t too dissimilar from the previous 600 series. The CUDA cores sit at 1536, with higher clocks speeds than previous GTX 600 series GPUs.
The reference GeForce GTX 780 comes with 3GB of GDDR5 in a 256-bit bus, while core clock speed is 863MHz Base Clock. The GPU Boost clock is 900MHz, but remember, this is the minimum you can expect to achieve; higher speeds are absolutely possible as we’ll see shortly.
Here’s what the detailed stats look like for this Gigabyte GTX 780 OC Windforce:
Doesn’t seem like too much extra, now does it? Wait until you see what happens when we turn it loose in our gaming tests and overclocking escapades.
For now, let’s take a closer look now at the card.
