ASUS TUF Gaming GeForce GTX 1660 Ti 6GB vs TUF Gaming X3 GeForce GTX 1660 Ti Advanced Edition 6GB

Since both GPUs have the same number of ROPs, and the TUF Gaming X3 GeForce GTX 1660 Ti Advanced Edition 6GB operates at slightly higher frequency, it also has higher pixel fillrate. Better maximum pixel fill rate allows more pixels to be drawn on screen per second, which results in increased performance, unless there are bottlenecks in other areas, such as texture fillrate, memory bandwidth or CPU speed.

Pixel fill rate was an important factor years ago, but not so much these days. Texture fill rate has more significance in modern games. Two factors, that influence this parameter, are the number of TMUs (Texture Mapping Units) and graphics frequency. Because both graphics cards have the same number of Texture Mapping Units (TMUs), and the ASUS TUF Gaming X3 GeForce GTX 1660 Ti Advanced Edition 6GB GPU runs at insignificantly higher rate, it also has higher texture fillrate. Better texture fill rate allows the graphics card to apply more textures and/or use more complex 3D effects for each texel, which improves visual appearance of games and generated images.

Single Precision performance illustrates how many single-precision floating point operations the graphics card can execute per second. The performance is measured in billions of Floating Point Operations Per Second, or GFLOPS. Generally, the more stream processors or CUDA cores the GPU has, and the the faster they operate at, the higher Single Precision performance will be. The ASUS TUF Gaming X3 GeForce GTX 1660 Ti Advanced Edition 6GB has an edge here. Higher single-precision performance number means the graphics unit will perform better in general computing applications. Since stream processors or CUDA cores are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

Maximum Double Precision performance is similar to the Single Precision performance, except that it applies to double-precision (64-bit) floating point operations. Since games do not use double-precision arithmetics, this characteristic is irrelevant to games performance. The ASUS TUF Gaming X3 GeForce GTX 1660 Ti Advanced Edition 6GB card is faster at processing 64-bit floating-point numbers.

Memory bandwidth of both GPUs is identical.
