Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GT 450 (OEM) should perform quite a bit faster than the Radeon HD 3470 256MB in general. (explain)

GeForce GT 450 (OEM)		96000 MB/sec
Radeon HD 3470 256MB		30400 MB/sec
	Difference: 65600 (216%)

Texel Rate

The GeForce GT 450 (OEM) should be a lot (approximately 493%) more effective at anisotropic filtering than the Radeon HD 3470 256MB. (explain)

GeForce GT 450 (OEM)		18960 Mtexels/sec
Radeon HD 3470 256MB		3200 Mtexels/sec
	Difference: 15760 (493%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 450 (OEM) is the winner, by far. (explain)

GeForce GT 450 (OEM)		18960 Mpixels/sec
Radeon HD 3470 256MB		3200 Mpixels/sec
	Difference: 15760 (493%)

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 max amount of information (measured in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
