Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6570 (OEM) 1GB		50 Watts
GeForce GT 430 (OEM)		60 Watts
	Difference: 10 Watts (20%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon HD 6570 (OEM) 1GB is much (approximately 39%) faster with regards to AF than the GeForce GT 430 (OEM). (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 4400 (39%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon HD 6570 (OEM) 1GB is a better choice, and very much so. (explain)

Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 2400 (86%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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