GeForce GT 130		75 Watts
	Difference: 25 Watts (50%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6570 (OEM) 1GB should be 140% faster than the GeForce GT 130 overall, due to its greater data rate. (explain)

Radeon HD 6570 (OEM) 1GB		28800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 16800 (140%)

Texel Rate

The Radeon HD 6570 (OEM) 1GB will be quite a bit (more or less 30%) faster with regards to texture filtering than the GeForce GT 130. (explain)

Radeon HD 6570 (OEM) 1GB		15600 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 3600 (30%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 130 is a better choice, and very much so. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon HD 6570 (OEM) 1GB		5200 Mpixels/sec
	Difference: 2800 (54%)

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 largest amount of information (measured in megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
