Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M270X should theoretically be much faster than the GeForce 9600 GT 1GB overall. (explain)

Radeon R9 M270X		72000 MB/sec
GeForce 9600 GT 1GB		57600 MB/sec
	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M270X should be a lot (approximately 39%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon R9 M270X		29000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 8200 (39%)

Pixel Rate

The Radeon R9 M270X will be just a bit (more or less 12%) better at anti-aliasing than the GeForce 9600 GT 1GB, and also capable of handling higher resolutions more effectively. (explain)

Radeon R9 M270X		11600 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 1200 (12%)

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 (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that can be processed per second. This number 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
