GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M365X will be a bit (approximately 19%) more effective at texture filtering than the GeForce 9600 GSO 512MB. (explain)

Radeon R9 M365X		37000 Mtexels/sec
GeForce 9600 GSO 512MB		31200 Mtexels/sec
	Difference: 5800 (19%)

Pixel Rate

The Radeon R9 M365X is much (more or less 42%) more effective at AA than the GeForce 9600 GSO 512MB, and also capable of handling higher resolutions more effectively. (explain)

Radeon R9 M365X		14800 Mpixels/sec
GeForce 9600 GSO 512MB		10400 Mpixels/sec
	Difference: 4400 (42%)

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 data (counted in MB per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
