GeForce GTX 750 Ti vs Geforce GTX 780

Intro

The GeForce GTX 750 Ti makes use of a 28 nm design. nVidia has set the core frequency at 1020 MHz. The GDDR5 memory is set to run at a frequency of 1350 MHz on this particular card. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Compare all that to the Geforce GTX 780, which comes with core speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 memory. It features 2304 SPUs as well as 192 Texture Address Units and 48 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
