GeForce GT 130 vs GeForce GTX 580 3GB

Intro

Compare that to the GeForce GTX 580 3GB, which features GPU core speed of 772 MHz, and 3072 MB of GDDR5 memory running at 1002 MHz through a 384-bit bus. It also is made up of 512 Stream Processors, 64 Texture Address Units, and 48 Raster Operation Units.

GeForce GT 130		12000 MB/sec
	Difference: 180384 (1503%)

Texel Rate

The GeForce GTX 580 3GB should be a lot (approximately 312%) faster with regards to AF than the GeForce GT 130. (explain)

GeForce GTX 580 3GB		49408 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 37408 (312%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 580 3GB is a better choice, and very much so. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 29056 (363%)

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 largest amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If 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 higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
