GeForce 9600 GSO ASUS 512		84 Watts
Radeon HD 6750		86 Watts
	Difference: 2 Watts (2%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 will be 300% quicker than the GeForce 9600 GSO ASUS 512 overall, because of its higher bandwidth. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 9600 GSO ASUS 512		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The GeForce 9600 GSO ASUS 512 will be just a bit (approximately 1%) more effective at anisotropic filtering than the Radeon HD 6750. (explain)

GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 300 (1%)

Pixel Rate

The Radeon HD 6750 should be much (about 76%) faster with regards to AA than the GeForce 9600 GSO ASUS 512, and also capable of handling higher resolutions while still performing well. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
	Difference: 5000 (76%)

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 (in units of MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out 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 fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
