Radeon HD 3470 512MB		30400 MB/sec
	Difference: 12800 (42%)

Texel Rate

The GeForce GT 440 1.5GB should be quite a bit (approximately 346%) more effective at texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 11056 (346%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GT 440 1.5GB is superior to the Radeon HD 3470 512MB, by a large margin. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11056 (346%)

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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
