Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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 bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The GeForce 9600 GSO ASUS 512 will be quite a bit (about 38%) faster with regards to texture filtering 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 running with a high screen resolution is important to you, then the GeForce 9600 GSO ASUS 512 is a better choice, by far. (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: Memory bandwidth is the largest 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 card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
