CUDA and OpenGL Performance
Besides our traditional gaming tests, we want to check out the GK110 GPU in computing and encoding applications. First goes the SmoothVideo Project benchmark – SVPMark 3.0.3a (the real-life test score):
The GeForce GTX Titan doesn’t show anything special here. It is close to the GeForce GTX 680 and doesn’t increase its score much when overclocked.
Next we measured the speed of HD video encoding in Xilisoft Video Converter version 7.7.2 which supports both AMD and Nvidia GPUs. We took a 2.5GB Full-HD video and converted it for iPad 4. The resulting file was about 750 MB large. A smaller time is better in this diagram:
Nvidia’s GPUs are superior to their AMD opponents as well as to the six-core Intel CPU in this test, but the GeForce GTX Titan is no better than the ordinary GeForce GTX 680. The dual-processor GeForce GTX 690 doesn’t provide any substantial benefits. Xilisoft Video Converter doesn’t seem to use all of the GK110’s capabilities.
The next test is DirectCompute Benchmark version 0.45b. We show you the DirectCompute and OpenCL scores in the diagram:
We also tried to check the GK110 out in the popular LuxMark but its latest version 2.0 didn’t support the GeForce GTX Titan, aborting the test with an error. So we could only benchmark the older cards:
The GeForce GTX Titan must be about as fast as the GeForce GTX 690 but we’ll only make sure after a GK110-compatible version of LuxMark comes out. So far we can only say that the Radeon series is much faster here.
