The GeForce 9600 GT 512MB should be just a bit (approximately 11%) more effective at texture filtering than the Radeon R5 M255. (explain)

GeForce 9600 GT 512MB		20800 Mtexels/sec
Radeon R5 M255		18800 Mtexels/sec
	Difference: 2000 (11%)

Pixel Rate

The GeForce 9600 GT 512MB will be a lot (about 38%) better at FSAA than the Radeon R5 M255, and will be capable of handling higher screen resolutions while still performing well. (explain)

GeForce 9600 GT 512MB		10400 Mpixels/sec
Radeon R5 M255		7520 Mpixels/sec
	Difference: 2880 (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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
