Radeon HD 4650 512MB 55 Watts
GeForce 9600 GSO ASUS 512 84 Watts
Difference: 29 Watts (53%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce 9600 GSO ASUS 512 should be much (approximately 38%) better at AF than the Radeon HD 4650 512MB. (explain)

GeForce 9600 GSO ASUS 512 26400 Mtexels/sec
Radeon HD 4650 512MB 19200 Mtexels/sec
Difference: 7200 (38%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 9600 GSO ASUS 512 is the winner, by a large margin. (explain)

GeForce 9600 GSO ASUS 512 6600 Mpixels/sec
Radeon HD 4650 512MB 4800 Mpixels/sec
Difference: 1800 (38%)

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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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