Texel Rate

The Radeon HD 6970 will be quite a bit (about 604%) better at texture filtering than the GeForce GT 130. (explain)

Radeon HD 6970		84480 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 72480 (604%)

Pixel Rate

The Radeon HD 6970 is much (about 252%) better at FSAA than the GeForce GT 130, and will be able to handle higher screen resolutions better. (explain)

Radeon HD 6970		28160 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 20160 (252%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 per second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
