AMD Radeon HD 7750 vs GIGABYTE Radeon R7 240 OC (GV-R724OC-2GI (rev. 2.0))

Since it has twice as many ROPs, the Radeon HD 7750 graphics unit provides significantly higher pixel fill rate, even though its graphics clock is slower. Having better pixel fillrate allows the GPU 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.

Although it has lower graphics frequency, the AMD Radeon HD 7750 comes with many more TMUs, resulting in better texture fill rate. Having better texture fill rate allows the graphics card to utilize more sophisticated 3D effects and/or apply more textures to each texel, which improves visual appearance of games and generated images.

Maximum Single Precision performance illustrates how fast the graphics card is at running applications, that process mainly single-precision floating point data. This performance is expressed in GFLOPS, or Giga (billions of) Floating Point Operations Per Second. As a rule, the faster CUDA cores or stream processors run at, and the more cores / processors the graphics card has, the higher Single Precision performance will be. The Radeon HD 7750 is faster here. Higher single-precision performance number means the graphics card will perform better in general computing applications. Since CUDA cores or stream processors are also used as vertex and geometry shaders for 3D image generation, higher performance is also beneficial to games.

Memory bandwidth parameter specifies 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 AMD Radeon HD 7750 comes with higher clocked memory of better kind. As such, it has more memory bandwidth.
