Texel Rate

The GeForce GTX 750 will be a lot (about 271%) faster with regards to texture filtering than the GeForce 9500 GT DDR2. (explain)

GeForce GTX 750		32640 Mtexels/sec
GeForce 9500 GT DDR2		8800 Mtexels/sec
	Difference: 23840 (271%)

Pixel Rate

The GeForce GTX 750 is a lot (approximately 271%) faster with regards to full screen anti-aliasing than the GeForce 9500 GT DDR2, and able to handle higher resolutions more effectively. (explain)

GeForce GTX 750		16320 Mpixels/sec
GeForce 9500 GT DDR2		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 MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure is worked out 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 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 most pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
