Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 750 should be much faster than the Radeon HD 3470 512MB in general. (explain)

GeForce GTX 750		80000 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 49600 (163%)

Texel Rate

The GeForce GTX 750 should be much (more or less 920%) faster with regards to texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 750		32640 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 29440 (920%)

Pixel Rate

The GeForce GTX 750 is quite a bit (about 410%) faster with regards to anti-aliasing than the Radeon HD 3470 512MB, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 750		16320 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 13120 (410%)

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: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video 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 number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
