Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce GTX 650 is 150% quicker than the Radeon R7 M265 overall, due to its higher data rate. (explain)

GeForce GTX 650		80000 MB/sec
Radeon R7 M265		32000 MB/sec
	Difference: 48000 (150%)

Texel Rate

The GeForce GTX 650 should be a lot (about 95%) more effective at AF than the Radeon R7 M265. (explain)

GeForce GTX 650		33856 Mtexels/sec
Radeon R7 M265		17400 Mtexels/sec
	Difference: 16456 (95%)

Pixel Rate

The GeForce GTX 650 should be quite a bit (more or less 192%) more effective at full screen anti-aliasing than the Radeon R7 M265, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 650		16928 Mpixels/sec
Radeon R7 M265		5800 Mpixels/sec
	Difference: 11128 (192%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
