GeForce 9800 GTX 70400 MB/sec
Radeon HD 4850 2GB 63552 MB/sec
Difference: 6848 (11%)

Texel Rate

The GeForce 9800 GTX should be a lot (about 73%) better at texture filtering than the Radeon HD 4850 2GB. (explain)

GeForce 9800 GTX 43200 Mtexels/sec
Radeon HD 4850 2GB 25000 Mtexels/sec
Difference: 18200 (73%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GTX is a better choice, but not by far. (explain)

GeForce 9800 GTX 10800 Mpixels/sec
Radeon HD 4850 2GB 10000 Mpixels/sec
Difference: 800 (8%)

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: Bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
