Memory Bandwidth

The GeForce GTX 750 Ti should in theory perform a little bit faster than the GeForce GTX 750 overall. (explain)

GeForce GTX 750 Ti		86400 MB/sec
GeForce GTX 750		80000 MB/sec
	Difference: 6400 (8%)

Texel Rate

The GeForce GTX 750 Ti is quite a bit (approximately 25%) faster with regards to anisotropic filtering than the GeForce GTX 750. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 8160 (25%)

Pixel Rate

Both cards have the exact same pixel fill rate, so theoretically they should be equally good at at FSAA, and be able to handle the same screen resolutions. (explain)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If 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 higher screen 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 by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
