GeForce 9600 GSO 768MB		38400 MB/sec
	Difference: 33600 (88%)

Texel Rate

The Radeon R9 M375X will be a lot (about 54%) better at anisotropic filtering than the GeForce 9600 GSO 768MB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
GeForce 9600 GSO 768MB		26400 Mtexels/sec
	Difference: 14200 (54%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M375X is a better choice, by a large margin. (explain)

Radeon R9 M375X		16240 Mpixels/sec
GeForce 9600 GSO 768MB		6600 Mpixels/sec
	Difference: 9640 (146%)

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 max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, 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 record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
