Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
Radeon RX 470 4GB		120 Watts
	Difference: 60 Watts (100%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 4GB will be 633% quicker than the GeForce GT 430 in general, due to its greater bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 182400 (633%)

Texel Rate

The Radeon RX 470 4GB should be much (more or less 958%) better at AF than the GeForce GT 430. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 107328 (958%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 470 4GB is a better choice, and very much so. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 26832 (958%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. 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.
