NVIDIA GeForce GTX 650Ti Boost Testing:

Testing of the NVIDIA GTX 650Ti Boost 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 including the GTX 650Ti Boost  will be using the 314.21 beta drivers. AMD-based cards will be using the Catalyst 13.1 drivers and latest CAP profile with the exception of the HD 7790 which will use the release press evaluation driver.

Overclocking:

  • GTX 650Ti Boost: Core 1215Hz, Memory 1603MHz

Using a Kepler core at its heart, the GTX 650Ti Boost edition overclocks much like any of the enthusiast cards such as the GTX 680 and GTX Titan. For this exercise I will be using EVGA Precision to overclock the GTX 650Ti Boost. Knowing where these cores normally start to show signs of instability, I moved the sliders up to a point where I was running a core boost clock of almost 1200MHz as my starting point. The maximum fan speed I could set was 74%, yet this kept the core at a modest 56 °C under load. A higher fan speed may have dropped the load temperatures but most certainly increased the noise signature from the card. The voltage used in Precision was set to 1150mv after failing to complete the stability testing phase of the overclock testing. Final settings were 1215MHz under boost on the core with a 1603MHz clock on the GDDR5 memory.

 

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.
