Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 7770		80 Watts
GeForce 9600 GSO 768MB		84 Watts
	Difference: 4 Watts (5%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7770 is 88% faster than the GeForce 9600 GSO 768MB overall, because of its higher data rate. (explain)

Radeon HD 7770		72000 MB/sec
GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon HD 7770 should be a lot (approximately 52%) faster with regards to texture filtering than the GeForce 9600 GSO 768MB. (explain)

Radeon HD 7770		40000 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 13600 (52%)

Pixel Rate

The Radeon HD 7770 should be quite a bit (more or less 142%) better at anti-aliasing than the GeForce 9600 GSO 768MB, and also should be able to handle higher screen resolutions more effectively. (explain)

Radeon HD 7770		16000 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9400 (142%)

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 data (measured in megabytes per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 amount of texture map elements (texels) that are applied per 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 graphics 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 number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
