Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M265X will be 25% faster than the GeForce 9600 GT 1GB in general, due to its higher data rate. (explain)

Radeon R9 M265X		72000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M265X will be just a bit (more or less 11%) faster with regards to anisotropic filtering than the GeForce 9600 GT 1GB. (explain)

Radeon R9 M265X		23000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 2200 (11%)

Pixel Rate

The GeForce 9600 GT 1GB is a little bit (about 13%) better at AA than the Radeon R9 M265X, and also able to handle higher screen resolutions more effectively. (explain)

GeForce 9600 GT 1GB		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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 better this number, the better the 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 number of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 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.
