GeForce GT 130 vs GeForce GTX 570

Intro

Compare those specs to the GeForce GTX 570, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 RAM running at 950 MHz through a 320-bit bus. It also is comprised of 480 Stream Processors, 60 TAUs, and 40 Raster Operation Units.

Texel Rate

The GeForce GTX 570 should be a lot (more or less 266%) better at AF than the GeForce GT 130. (explain)

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

Pixel Rate

The GeForce GTX 570 should be much (more or less 266%) more effective at FSAA than the GeForce GT 130, and will be capable of handling higher resolutions more effectively. (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: Bandwidth is the max amount of information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out 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 card's 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 processed in one 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 applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
