Radeon HD 3650 512MB 25600 MB/sec
Difference: 4800 (19%)

Texel Rate

The Radeon HD 3650 512MB is quite a bit (more or less 81%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)

Radeon HD 3650 512MB 5800 Mtexels/sec
Radeon HD 3470 512MB 3200 Mtexels/sec
Difference: 2600 (81%)

Pixel Rate

The Radeon HD 3470 512MB is a small bit (more or less 10%) faster with regards to anti-aliasing than the Radeon HD 3650 512MB, and also should be capable of handling higher screen resolutions more effectively. (explain)

Radeon HD 3470 512MB 3200 Mpixels/sec
Radeon HD 3650 512MB 2900 Mpixels/sec
Difference: 300 (10%)

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 (in units of megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
