	Difference: 14400 (25%)

Texel Rate

The Radeon R9 M275X should be quite a bit (approximately 73%) faster with regards to texture filtering than the GeForce 9600 GT 1GB. (explain)

Radeon R9 M275X		36000 Mtexels/sec
GeForce 9600 GT 1GB		20800 Mtexels/sec
	Difference: 15200 (73%)

Pixel Rate

The Radeon R9 M275X will be a lot (about 38%) more effective at FSAA than the GeForce 9600 GT 1GB, and capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R9 M275X		14400 Mpixels/sec
GeForce 9600 GT 1GB		10400 Mpixels/sec
	Difference: 4000 (38%)

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 (measured in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. 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 number of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
