Texel Rate

The GeForce GTX 750 is much (approximately 85%) faster with regards to texture filtering than the GeForce GT 240 GDDR5. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce GT 240 GDDR5		17600 Mtexels/sec
	Difference: 15040 (85%)

Pixel Rate

The GeForce GTX 750 is much (about 271%) faster with regards to FSAA than the GeForce GT 240 GDDR5, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce GT 240 GDDR5		4400 Mpixels/sec
	Difference: 11920 (271%)

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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface within a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, 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 could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
