It's completely normal for GPU time to be bigger than CPU time. The CPU can start work on the next frame whilst the GPU is rendering the current frame. There's no single place to say the frame time - the horizontal lines across the GPU and CPU graphs tell you what the time is for that system. So, in your GPU stats you're often rendering at 100fps, apart from periodic spikes that cause you to drop to 60fps and 30fps very occasionally. The CPU seems to be fastest when the GPU is slowest.
