Texel Rate

The GeForce GTX 750 Ti will be quite a bit (approximately 21%) faster with regards to texture filtering than the GeForce 9800 GT 1GB. (explain)

GeForce GTX 750 Ti		40800 Mtexels/sec
GeForce 9800 GT 1GB		33600 Mtexels/sec
	Difference: 7200 (21%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 750 Ti is superior to the GeForce 9800 GT 1GB, by a large margin. (explain)

GeForce GTX 750 Ti		16320 Mpixels/sec
GeForce 9800 GT 1GB		9600 Mpixels/sec
	Difference: 6720 (70%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
