This means that an overclocked GTX 780 crosses those few 60fps thresholds that the stock GTX 780 fell just shy of, including the minimum framerate in HItman: Absolution, and the average framerate in Crysis 3. Actual scaling depends on the game – not every game scales well with higher clockspeeds alone – but in most games we at least pick up the 17% lower bound that comes with the memory overclock. Meanwhile on the memory side NVIDIA’s solid memory controller implementation once more shines through, with our sample easily going from a 6GHz memory clock to a 7GHz memory clock, a 1GHz (17%) improvement.Īnd what do we get for our efforts? In short, thanks to the fact that GTX Titan is only 11% faster than GTX 780 on average in the first place, GTX 780 can easily exceed Titan’s stock performance when overclocked. On our sample we’ve been able to push it ahead by 200MHz, moving the base clock from 863MHz to 1063MHz, a 23% improvement. The end result is that while the GTX 780 isn’t going to be an overclocking champion, it’s in a good position to satisfy overclockers. Compounding all of this is the fact that at stock GTX 780 is more often temperature limited than it is TDP limited, amplifying the factor we have the greatest control over (the temperature throttle) and minimizing the factor we have the least control over (the TDP limit). So while GTX 780 can’t necessarily clock any higher than GTX Titan, the additional TDP headroom means that it’s more likely to reach its higher boost bins more often, making overclocking more effective. This is significant because GTX 780 packs a GPU with fewer enabled SMXes than GTX Titan, and perhaps more importantly half as many RAM chips. On the other hand GTX 780 is built against the same power delivery requirements as GTX Titan, with a stock TDP limit of 250W. On the one hand it’s already the highest clocked GK110 part, with a base clock of 863MHz, making it the GK110 part closest to any practical clockspeed limits. When it comes to overclocking, GTX 780 is in an interesting spot. So as an addendum to last week’s review, let’s take a look at GTX 780 overclocking. Especially not after seeing just how far GTX 780 could overclock. Although we didn’t have enough time to include our GeForce GTX 780 overclocking results in our review of NVIDIA’s latest card, we didn’t want to discard them entirely.
