Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 650 Ti should in theory perform quite a bit faster than the Radeon HD 3470 512MB overall. (explain)

GeForce GTX 650 Ti		86400 MB/sec
Radeon HD 3470 512MB		30400 MB/sec
	Difference: 56000 (184%)

Texel Rate

The GeForce GTX 650 Ti will be quite a bit (approximately 1756%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)

GeForce GTX 650 Ti		59392 Mtexels/sec
Radeon HD 3470 512MB		3200 Mtexels/sec
	Difference: 56192 (1756%)

Pixel Rate

The GeForce GTX 650 Ti is a lot (approximately 364%) more effective at anti-aliasing than the Radeon HD 3470 512MB, and should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 650 Ti		14848 Mpixels/sec
Radeon HD 3470 512MB		3200 Mpixels/sec
	Difference: 11648 (364%)

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 (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling 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 the video card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
