GeForce GTX 750 vs GeForce GTX 750 Ti

Intro

Compare those specs to the GeForce GTX 750 Ti, which uses a 28 nm design. nVidia has set the core speed at 1020 MHz. The GDDR5 memory is set to run at a speed of 1350 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 Ti should perform just a 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 (about 25%) more effective at 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 exactly the same pixel rate, so in theory 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 max amount of information (measured in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
