Stone Giant is a benchmark tech demo that showcases and measures DirectX 11 performance using the BitSquid Engine. This is a very heavy tessellation dependent benchmark which runs very well on nVidia hardware. We are testing at 1080p with Tessellation levels set to Medium.
The PNY GTX 570 and HD 6950 both produced good results in our Stone Giant testing. The GTX 570 managed a very respectable minimum of 47.25 frames per second and an average frame rate of 76.11. The GTX 570 average frame rate is close to 12 frames per second faster then the unlocked 6950 in this tessellation heavy benchmark.
