NVIDIA GeForce GTX Titan Testing:
Testing of the NVIDIA GTX Titan 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 316.96 beta drivers while the GTX Titan will run the 314.09 driver. The AMD-based cards will be using the Catalyst 13.1 drivers and latest CAP profile.

Comparison Video Cards:
- NVIDIA GTX Titan: Core 1124-1150MHz, Memory 1624MHz
Manual overclocking on NVIDIA's latest creation is much the same as the GK104-based GTX 6XX series cards. By utilizing a clock speed increase managed as a Boost clock, the Kepler architecture works much like the latest Core series processors from Intel in some respects. By manually tweaking the core and memory clock speeds I was able to reach upwards of 1150MHz in some games and 1124MHz in others on the GTX Titan Kepler core even though the target temperature was not reached. Adjusting the memory sliders in EVGA's Precision overclocking tool I was able to squeeze the 6GB of memory to a high of 1624MHz.
These increases amount to a 20% boost on the core and just over 8% on the GDDR5 memory. Reasonably stout on the core but less so on the memory. Using the overvoltage feature of GPU Boost 2.0 can overclock some additional clock speed if the core can handle it. However you will have to acknowledge that you understand the risks realizing that the voltage levels may impact the lifespan of the silicon. With only two AIB partners in the North American market (ASUS and EVGA), the available overclocking tools will be ASUS GPU Tweak and EVGA's Precision tool, which we used as our overclocking tool for this review.
Manual overclocking is not the only way to see a performance boost with the GTX Titan. GPU Boost 2.0 will dynamically adjust the clock speed, voltage, and fan speeds to gain the best possible thermal and clock speed performance. By adjusting the target temperature (80 °C stock) you can see a boost in clock speed with nothing other than moving a slider and enjoying the game. The boost clock for the GTX Titan is supposed to be 876MHz while running up against the target temperature of 80 °C. One thing I saw was that the clock speeds on the core were routinely above 950MHz showing that the GTX Titan has indeed hit that sweet spot utilizing GPU Boost 2.0. Noise and GPU thermals are kept in check with the new Vapor Chamber cooling solution and all new fin array. In my testing I saw a maximum of 63 °C during the overclocked testing.
Maximum Clock Speeds:
Testing for the maximum clock speed consisted of looping Unigine 3.0 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.
