Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon HD 4670 1GB		70 Watts
GeForce 9600 GSO 1.5GB		84 Watts
	Difference: 14 Watts (20%)

Memory Bandwidth

Theoretically speaking, the GeForce 9600 GSO 1.5GB is 9% quicker than the Radeon HD 4670 1GB in general, due to its greater bandwidth. (explain)

GeForce 9600 GSO 1.5GB		38400 MB/sec
Radeon HD 4670 1GB		35200 MB/sec
	Difference: 3200 (9%)

Texel Rate

The GeForce 9600 GSO 1.5GB is a small bit (about 10%) faster with regards to anisotropic filtering than the Radeon HD 4670 1GB. (explain)

GeForce 9600 GSO 1.5GB		26400 Mtexels/sec
Radeon HD 4670 1GB		24000 Mtexels/sec
	Difference: 2400 (10%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9600 GSO 1.5GB is superior to the Radeon HD 4670 1GB, but not by far. (explain)

GeForce 9600 GSO 1.5GB		6600 Mpixels/sec
Radeon HD 4670 1GB		6000 Mpixels/sec
	Difference: 600 (10%)

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 (counted in megabytes per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 number of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher 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 record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
