Texel Rate

The GeForce 9800 GT 512MB should be quite a bit (approximately 34%) faster with regards to AF than the GeForce GTS 450. (explain)

GeForce 9800 GT 512MB		33600 Mtexels/sec
GeForce GTS 450		25056 Mtexels/sec
	Difference: 8544 (34%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTS 450 is superior to the GeForce 9800 GT 512MB, by far. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce 9800 GT 512MB		9600 Mpixels/sec
	Difference: 2928 (31%)

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 data (in units of MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
