Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce GTX 465 should be 237% quicker than the Radeon HD 3470 512MB in general, due to its greater data rate. (explain)

GeForce GTX 465		102592 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 72192 (237%)

Texel Rate

The GeForce GTX 465 will be quite a bit (approximately 735%) better at texture filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 465		26708 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 23508 (735%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 465 is a better choice, and very much so. (explain)

GeForce GTX 465		19424 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 16224 (507%)

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 data (in units of megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few 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.
