Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R9 M265X should perform quite a bit faster than the GeForce 9600 GSO 512MB overall. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9600 GSO 512MB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The GeForce 9600 GSO 512MB will be a lot (more or less 36%) faster with regards to texture filtering than the Radeon R9 M265X. (explain)

GeForce 9600 GSO 512MB		31200 Mtexels/sec
Radeon R9 M265X		23000 Mtexels/sec
	Difference: 8200 (36%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9600 GSO 512MB is a better choice, but not by far. (explain)

GeForce 9600 GSO 512MB		10400 Mpixels/sec
Radeon R9 M265X		9200 Mpixels/sec
	Difference: 1200 (13%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
