Radeon HD 3690/3830 26496 MB/sec
Difference: 3904 (15%)

Texel Rate

The Radeon HD 3690/3830 is much (more or less 234%) faster with regards to texture filtering than the Radeon HD 3470 256MB. (explain)

Radeon HD 3690/3830 10688 Mtexels/sec
Radeon HD 3470 256MB 3200 Mtexels/sec
Difference: 7488 (234%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon HD 3690/3830 is superior to the Radeon HD 3470 256MB, and very much so. (explain)

Radeon HD 3690/3830 10688 Mpixels/sec
Radeon HD 3470 256MB 3200 Mpixels/sec
Difference: 7488 (234%)

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 information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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