Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 6750		86 Watts
GeForce 8800 GTS (G92)		135 Watts
	Difference: 49 Watts (57%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 6750 will be 3% quicker than the GeForce 8800 GTS (G92) overall, because of its higher data rate. (explain)

Radeon HD 6750		64000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 1920 (3%)

Texel Rate

The GeForce 8800 GTS (G92) will be much (approximately 59%) more effective at texture filtering than the Radeon HD 6750. (explain)

GeForce 8800 GTS (G92)		41600 Mtexels/sec
Radeon HD 6750		26100 Mtexels/sec
	Difference: 15500 (59%)

Pixel Rate

The Radeon HD 6750 will be just a bit (approximately 12%) more effective at FSAA than the GeForce 8800 GTS (G92), and able to handle higher screen resolutions without slowing down too much. (explain)

Radeon HD 6750		11600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 1200 (12%)

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 (in units of MB per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
