Radeon HD 3470 256MB		30400 MB/sec
	Difference: 12800 (42%)

Texel Rate

The GeForce GT 440 1.5GB will be quite a bit (more or less 346%) more effective at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 11056 (346%)

Pixel Rate

The GeForce GT 440 1.5GB should be much (approximately 346%) more effective at FSAA than the Radeon HD 3470 256MB, and will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
Radeon HD 3470 256MB		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 maximum amount of information (in units of megabytes per second) that can be transferred across 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 memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could 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 Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
