Usage: Written by Microsoft's own silicon engineers but published as a conference presentation, so it is held at tier B rather than treated as vendor documentation. Slide 10, 'GPU Specs', quantifies the graphics processor in shader instructions per second, fill rate and triangle rate and states no floating-point rate, which is why the console's FP32 row stays unknown.
