  • Theoretical performance comparison

    Real-world game, 3D graphics and compute performance is dependent on several vital GPU parameters, including pixel fillrate, texture 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

    Incorporating twice as many ROPs helps the GeForce GT 740M graphics card to deliver higher pixel fill rate, even though it has slower graphics clock. Having better pixel fillrate allows the graphics card to draw more pixels on screen and off screen, which is beneficial for some 3D effects in games, or when playing at higher display resolutions.

    Texture fill rate (gigatexels/s)











    Higher is better

    Even though its graphics frequency is lower, the NVIDIA GeForce GT 740M comes with twice as many Texture Mapping Units (TMUs), resulting in better texture fill rate. Having better maximum texture fill rate allows the graphics card to map more textures and/or use more sophisticated 3D effects for each textured picture element, which improves visual appearance of games and generated images.

    Single Precision performance (GFLOPS)











    Higher is better

    Single Precision performance indicates how many single-precision floating point operations the GPU can execute per second. This performance is measured in billions of Floating Point Operations Per Second, or GFLOPS. As a rule, the faster CUDA cores or stream processors run at, and the more cores / processors the graphics unit has, the higher Single Precision performance will be. The NVIDIA GeForce 840M graphics card is faster here. Higher single-precision performance number means the GPU 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.

    Memory bandwidth (GB/s)











    Higher is better

    Memory bandwidth parameter tells how much memory (in Gigabytes) the graphics card can read from or write to dedicated memory per second. Cards with higher memory bandwidth have better performance at high display resolutions, or when using large and detailed textures, and/or utilizing complex 3D effects and filters, like anti-aliasing. The bandwidth depends on memory type, speed, and memory interface width. Specifically, the GeForce GT 740M graphics card comes with wider memory bus. As a result, it has substantially higher memory bandwidth.
