The GeForce 9600 GSO ASUS 512 will be a lot (more or less 428%) more effective at anisotropic filtering than the Radeon HD 6450 (OEM). (explain)

GeForce 9600 GSO ASUS 512		26400 Mtexels/sec
Radeon HD 6450 (OEM)		5000 Mtexels/sec
	Difference: 21400 (428%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9600 GSO ASUS 512 is a better choice, and very much so. (explain)

GeForce 9600 GSO ASUS 512		6600 Mpixels/sec
Radeon HD 6450 (OEM)		2500 Mpixels/sec
	Difference: 4100 (164%)

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 information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster 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 number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
