Texel Rate

The GeForce 8800 GT 1GB will be much (about 630%) faster with regards to anisotropic filtering than the Radeon HD 4350. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
Radeon HD 4350		4600 Mtexels/sec
	Difference: 29000 (630%)

Pixel Rate

The GeForce 8800 GT 1GB is a lot (approximately 317%) better at AA than the Radeon HD 4350, and also should be capable of handling higher resolutions more effectively. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
Radeon HD 4350		2300 Mpixels/sec
	Difference: 7300 (317%)

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 largest amount of information (measured in MB per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
