NVIDIA GeForce GTX 780 Review


NVIDIA GeForce GTX 780 Testing:

Testing of the NVIDIA GTX 780 will consist of running it and comparison cards through the OverclockersClub.com suite of games and synthetic benchmarks. This will test the performance against many popular competitors. Comparisons will be made to cards of a range of capabilities to show where each card falls on the performance ladder. The games used are some of today's newest and most popular titles, which should be able to provide an idea of how the cards perform relative to each other.

The system specifications will remain the same throughout the testing. No adjustments will be made to the respective control panels during the testing to approximate the performance the end user can expect with a stock driver installation. I will first test the cards at stock speeds, and then overclocked to see the effects of an increase in clock speed. The cards will be placed in order from highest to lowest performance in each graph to show where they fall by comparison. The NVIDIA comparison cards will be using the 320.00 drivers while AMD-based cards will be using the Catalyst 13.5 beta drivers and latest CAP profile. The results generated in my testing reached by utilizing the latest FCAT tools to illustrate the true picture of the gaming experience. To do so will require a second PC setup to capture the data stream generated by the compared video cards.

  • NVIDIA GTX 780: Core 1202MHz, Memory 1612MHz

With the GTX 780 we get a bit of added voltage to increase the clock speeds to meet our needs. Most importantly more performance in games and synthetic benchmarks. Based on some history with the rest of the Kepler architecture, it was pretty easy to reach the limits of the card with the factory air cooling solution. GPU Boost 2.0 allows some additional leeway when it comes to overclocking by allowing the end user to set both power and thermal limits on the clocks or each one independently. Initially they are linked together so that when you increase one the other follows with a maximum limit of 106% on the power limit and 94 °C for the thermal limit. As you will see in the temperature section we came no where near that thermal limit so the limit for this card was the available voltage and clock speeds it would run with that voltage.

Firing up the latest beta version of EVGA's PrecisionX overclocking and tuning utility, I increased the fan speed to the maximum level; this is to provide the best possible cooling scenario as well as looking at the worst noise levels the fan would ever deliver. I then maxed out the voltage and started increasing clock speeds. The first adjustment netted a dynamic boost clock of 1100MHz on the core for a hefty 200MHz boost over the reference boost clock. Further tuning got the boost clock up to 1202MHz, which proved stable through all of the gaming tests. I could run higher clock speeds through some of the games but not all with 3DMark being the primary failure point. Even so that's about a 34% boost in clock speed on the Kepler core. The memory was a lot less forgiving when it came to overclocking, only reaching 1612MHz or about 7%. Every bit helps when you chase benchmark scores.


Maximum Clock Speeds:

Testing for the maximum clock speed consisted of looping Unigine Heaven 4.0 for 30 minutes each to see where the clock speeds failed when pushed. If the clock speed adjustment failed, then the clock speeds and tests were rerun until they passed a full hour of testing.
