Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7750		55 Watts
GeForce 9600 GT 1GB		95 Watts
	Difference: 40 Watts (73%)

Memory Bandwidth

In theory, the Radeon HD 7750 should be much faster than the GeForce 9600 GT 1GB overall. (explain)

Radeon HD 7750		72000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon HD 7750 should be a lot (approximately 23%) more effective at anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 4800 (23%)

Pixel Rate

The Radeon HD 7750 will be quite a bit (approximately 23%) more effective at FSAA than the GeForce 9600 GT 1GB, and should be capable of handling higher resolutions without losing too much performance. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 2400 (23%)

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 (counted in MB per second) that can be moved over the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
