Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M265 is 11% quicker than the GeForce GT 430 in general, due to its higher data rate. (explain)

Radeon R7 M265		32000 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 3200 (11%)

Texel Rate

The Radeon R7 M265 is much (approximately 55%) better at AF than the GeForce GT 430. (explain)

Radeon R7 M265		17400 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 6200 (55%)

Pixel Rate

The Radeon R7 M265 is much (approximately 107%) faster with regards to AA than the GeForce GT 430, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R7 M265		5800 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 3000 (107%)

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 information (measured in megabytes per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the 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 figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
