GeForce GT 130 vs Radeon R9 285

Intro

Compare all that to the Radeon R9 285, which makes use of a 28 nm design. AMD has set the core frequency at 918 MHz. The GDDR5 RAM runs at a frequency of 1375 MHz on this specific model. It features 1792 SPUs as well as 112 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 130		12000 Mtexels/sec
	Difference: 90816 (757%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon R9 285 is superior to the GeForce GT 130, and very much so. (explain)

Radeon R9 285		29376 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 21376 (267%)

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 maximum amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
