GeForce GT 130 vs GeForce GTX 570

Intro

Compare all that to the GeForce GTX 570, which comes with GPU core speed of 732 MHz, and 1280 MB of GDDR5 RAM running at 950 MHz through a 320-bit bus. It also features 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

GeForce GT 130		12000 MB/sec
	Difference: 140000 (1167%)

Texel Rate

The GeForce GTX 570 will be much (about 266%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 31920 (266%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is superior to the GeForce GT 130, by a large margin. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 21280 (266%)

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 max amount of data (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on 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 potential to reach the max fill rate.
