Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5830 should perform quite a bit faster than the Radeon HD 3470 256MB in general. (explain)

Radeon HD 5830 128000 MB/sec
Radeon HD 3470 256MB 30400 MB/sec
Difference: 97600 (321%)

Texel Rate

The Radeon HD 5830 should be quite a bit (about 1300%) more effective at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

Radeon HD 5830 44800 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 41600 (1300%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 5830 is a better choice, by a large margin. (explain)

Radeon HD 5830 12800 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 9600 (300%)

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 data (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units 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 processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
