Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce GTX 275, in theory, should be much faster than the Radeon R7 M260 overall. (explain)

GeForce GTX 275		127008 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 111008 (694%)

Texel Rate

The GeForce GTX 275 should be a lot (about 195%) more effective at anisotropic filtering than the Radeon R7 M260. (explain)

GeForce GTX 275		50640 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 33480 (195%)

Pixel Rate

The GeForce GTX 275 is much (more or less 210%) better at AA than the Radeon R7 M260, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce GTX 275		17724 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 12004 (210%)

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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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