Texel Rate

The GeForce 8800 GS should be a lot (approximately 164%) better at texture filtering than the GeForce GT 220 GDDR3. (explain)

GeForce 8800 GS 26400 Mtexels/sec
GeForce GT 220 GDDR3 10000 Mtexels/sec
Difference: 16400 (164%)

Pixel Rate

The GeForce 8800 GS is much (approximately 32%) better at FSAA than the GeForce GT 220 GDDR3, and also capable of handling higher screen resolutions more effectively. (explain)

GeForce 8800 GS 6600 Mpixels/sec
GeForce GT 220 GDDR3 5000 Mpixels/sec
Difference: 1600 (32%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better 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 maximum number of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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 of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
