Testing:

Testing of the NVIDIA GTX 650Ti  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 adjustment will be made to the respective control panels during the testing, with the exception of the 3DMark 11 testing, where PhysX will be disabled in the NVIDIA Control Panel, if applicable. 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 latest press release driver will be used in testing of the GTX 650Ti, while the balnce of the NVIDIA cards are using 306.23; AMD will be using Catalyst 12.8 drivers.

Overclocking:

  • NVIDIA GTX 650 Ti Core 1228MHz, Memory 1493MHz

Overclocking the latest Kepler card in the product stack, the GTX 650Ti, is a little like walking back to last year without the use of NVIDIA's GPU Boost feature. Not having to worry about how the clock speed will swing based on the power window makes this card a breeze to overclock. Set the speed you want and see if it fails, wash, rinse, and repeat. By using any of the popular overclocking utilities that support NVIDIA's Kepler architecture such as MSI Afterburner, EVGA Precision or ASUS GPU Tweak you can boost up the clock speeds, voltage, and fan speeds.

To overclock the GTX 650Ti I used MSI Afterburner and adjusted the voltage and fan speed sliders to the maximum level and started tweaking the clock speed. After looking at just about every card in the stack I had a good Idea as to where the final clock speed might fall so I started just south of 1200MHz and upped the core clock until the card would fail during my testing. I could hit as high as 1240MHz in some tests but not all of them so the clock speed was dropped 12MHz to 1228MHz where each and every test would pass. The memory was clocked in much the same way although with a much lower starting point, as the maximum clock speed I could pull from the memory was just under 1500MHz.

When you look at the 1228MHz clock on the core that is a 32+% jump in clock speed over the base clock speed of 925MHz. Pretty sick overclocking from the lower end of the product stack. The overclock on the 1GB of GDDR5 memory as a percentage is not nearly as exciting but still delivers a solid 10+% improvement over the baseline 1350MHz. Overclocking is certainly worth the effort on this card. By boosting the fan speed to stabilize the overclock the card temperatures did not deviate much from the stock testing. Stock versus overclocked I saw a one degree swing in the temperatures delivered by the GTX 650Ti. Overclocking potential and cooling are excellent. I cannot wait to see what the non-reference designs from the board partners are capable of if this solid little reference card can swing the big numbers.

 

Maximum Clock Speeds:

Testing for the maximum clock speed consists of looping Unigine 3.0 for 30 minutes each to see where the clock speeds fail when pushed. If the clock speed adjustment fails, then the clock speeds are adjusted and the test is rerun until each card passes the testing.
