Theoretical performance comparison

Each graphics card has several theoretical parameters that affect real-world game, 3D graphics and compute performance. They 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.

Pixel fill rate (gigapixels/s)

Higher is better
Pixel fillrate number shows how many pixels a card can draw on screen and off screen. The higher this number, the higher maximum display resolution and frame rate the GPU can support. The maximum theoretical pixel fillrate is dependent on graphics clock and the number of ROPs (Raster Operations Pipelines). Since both characteristics are identical between GPUs, their pixel fillrate is also equal.

Higher is better
Both models have the same number of TMUs and the same graphics frequency, as a result their texture fillrate is identical.

Higher is better
Single Precision performance is useful for estimating card's maximum speed in applications, that process only single-precision floating point data. The performance is expressed in billions of Floating Point Operations Per Second, or GFLOPS. Since FP calculations are performed by shaders, stream processors or CUDA cores, the performance is directly proportional to their number. Processor clock speed also influences it. These two graphics cards have the same maximum single-precision performance.

Like Single Precision performance, Double Precision one also provides the maximum number of floating-point operations, executed by CUDA cores or stream processors, but it refers to double precision (64-bit) operations. Both graphics cards have the same performance.
