Texel Rate

The GeForce GTX 650 Ti will be a lot (approximately 52%) more effective at anisotropic filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 20224 (52%)

Pixel Rate

The GeForce GTX 650 Ti is a small bit (about 1%) faster with regards to anti-aliasing than the GeForce 8800 Ultra, and also should be able to handle higher resolutions better. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 160 (1%)

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 megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
