MSI GeForce 7800 GT vs NVIDIA GeForce 7800 GTX 512

Since both graphics cards have the same number of ROPs, and the NVIDIA GeForce 7800 GTX 512 GPU is clocked higher, it also has higher pixel fillrate. Better maximum pixel fill rate means that the graphics card can draw more pixels on and off screen each second, increasing overall performance, unless there are bottlenecks in other areas, such as memory bandwidth or texture mapping.

The GeForce 7800 GTX 512 has more TMUs than the GeForce 7800 GT. What's more, its graphics clock speed is higher, as a result, its texture fillrate is much higher. Having better maximum texture fill rate allows the GPU to map more textures and/or utilize more sophisticated 3D effects for each texel, which improves games visual appearance.

 

Memory bandwidth parameter tells how much memory (in Gigabytes) the graphics card can read from or write to dedicated memory per second. GPUs 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. Memory type, speed, and memory interface width all affect the bandwidth value. In this case, the NVIDIA GeForce 7800 GTX 512 graphics card comes with higher clocked memory. As such, it has significantly higher memory bandwidth.
