Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 750		55 Watts
GeForce GTX 650		64 Watts
	Difference: 9 Watts (16%)

Memory Bandwidth

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

Texel Rate

The GeForce GTX 650 should be a small bit (approximately 4%) more effective at AF than the GeForce GTX 750. (explain)

GeForce GTX 650		33856 Mtexels/sec
GeForce GTX 750		32640 Mtexels/sec
	Difference: 1216 (4%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 650 is a better choice, though not by far. (explain)

GeForce GTX 650		16928 Mpixels/sec
GeForce GTX 750		16320 Mpixels/sec
	Difference: 608 (4%)

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 data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
