GeForce GT 130 vs Radeon R9 280X

Intro

Compare all that to the Radeon R9 280X, which comes with a GPU core clock speed of 850 MHz, and 3072 MB of GDDR5 memory set to run at 1500 MHz through a 384-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

GeForce GT 130		12000 MB/sec
	Difference: 276000 (2300%)

Texel Rate

The Radeon R9 280X is much (about 807%) faster with regards to 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 a lot (more or less 240%) more effective at FSAA than the GeForce GT 130, and will be capable of handling higher screen resolutions better. (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 (counted in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
