Radeon HD 4770 51200 MB/sec
GeForce GT 430 (OEM) 28800 MB/sec
Difference: 22400 (78%)

Texel Rate

The Radeon HD 4770 will be quite a bit (about 114%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

Radeon HD 4770 24000 Mtexels/sec
GeForce GT 430 (OEM) 11200 Mtexels/sec
Difference: 12800 (114%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 4770 is a better choice, by a large margin. (explain)

Radeon HD 4770 12000 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 9200 (329%)

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 maximum amount of information (counted in megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher 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 most pixels the graphics card could possibly record to its local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
