	Difference: 276000 (2300%)

Texel Rate

The Radeon R9 280X is a lot (more or less 807%) more effective at anisotropic filtering than the GeForce GT 130. (explain)

Radeon R9 280X		108800 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 96800 (807%)

Pixel Rate

The Radeon R9 280X will be much (approximately 240%) more effective at FSAA than the GeForce GT 130, and also will be able to handle higher resolutions without losing too much performance. (explain)

Radeon R9 280X		27200 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 19200 (240%)

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 maximum 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 must be multiplied by 2 once 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 anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

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