Nvidia Pascal GPU has 17 billion transistors

With manual tuning, we settled on a +200MHz core overclock, +725MHz on the GDDR5X (11.45GHz), with the overvoltage set to "100%" (whatever that means—it's not a doubling of the voltage, just to be clear). In practice, looking at actual GPU Boost 3.0 clock speeds running stock vs. overclocked, we saw 2.0-2.1GHz on the core (vs. 1700-1733MHz), so we got a healthy 15 percent overclock on the core and memory. Results may vary, but our sample card looks to be a bit less impressive than other cards, so 2.0GHz and more looks attainable.

Performance improves on average by 10-15 percent, except at 1080p where we start to hit CPU limits in a few titles. We'll likely see factory overclocked cards with aftermarket coolers at some point, and some of those will almost certainly exceed what we're able to achieve with the Founders Edition. Even better, many of the factory overclocked cards will likely cost less than the Founders Edition. But if the 30 percent jump in performance over Titan X wasn't enough to get you excited, perhaps tacking on another 15 percent with overclocking will do the trick.
