Testing:

Testing the latest card from NVIDIA, the GTX 480, will consist of running the card through the OverclockersClub.com suite of games and synthetic benchmarks to test the performance of the GTX 480 against many popular competitors to gauge its performance. The games used are some of today's popular titles to give you an idea on how the cards perform relative to one another. 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 Vantage testing where PhysX will be disabled in the NVIDIA control panel. Clock speeds on each card are left at stock speeds. I will test the GTX 480 at both stock speeds and then overclocked if the tools are available to see how much additional performance is available when you choose to overclock the card and see if it shows any significant improvement in performance for the effort.

Overclocked settings:

  • nVidia GTX 480 804MHz/1608MHz/1058MHz

Early on I found that there were not any readily available tools to overclock the GTX 480 or read the clock speeds correctly. Fortunately, NVIDIA had that slight problem covered with the latest beta implementation of GPU-z and EVGA's Precision overclocking tool. When you take a look at the screenshot you will notice that the core clock speed for the GPU core is not an available option. Looks like something is wrong, but really is it? The short answer is no. The reason that the core clock speed is not visible is that with the GF 100 Fermi architecture the GPU core clock speed is controlled by the shader clock speed. So in essence the two are linked. Once you get past that, overclocking is pretty much like any other card. Bump the clock speeds and test! I moved up in 50MHz jumps on the shader/core clocks until I reached the point where a lock up or driver failure was my signal to back it down. I reached that point at just over 1600MHz. By backing the clocks down until I reached a point where I could pass the benchmarks and play games for well over an hour at 2560x1600. The clock speeds I ended up with were 1609MHz, a 207MHz jump over the factory 1401MHz. I used the same technique to overclock the memory speed reaching a maximum of 2115MHz, an increase of 167MHz over the factory specification of 1948MHz. All while keeping the fan speed around the 60% mark as 100% did not seem to give me any higher clock speed. Go figure!
