Theoretical performance comparison

Each GPU has several vital theoretical parameters that influence real-world game, 3D graphics and compute performance. These are texture fillrate, pixel fillrate, memory bandwidth, single-precision performance and double-precision performance. Below you will find why they are important, and which graphics card has better characteristics.

Higher is better
Pixel fillrate number determines how many pixels a graphics unit can draw on screen and off screen. Higher numbers allow GPUs to support higher maximum display resolutions and frame rates. The maximum pixel fillrate is dependent on graphics clock speed and the number of ROPs. Since both characteristics are identical between cards, their pixel fillrate is also equal.
