This is a side by side comparison of an I7 HexaCore processor and the GeForce GTX 970 GPU. In each frame the frame number equals the number of samples. By the end of the video at frame 1000 the image becomes very clear and the shadows inside the cabin are much more smooth and less grainy.
Check out my newer video where I compare this against 2 GPUs.
