GeForce GT 130 vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which features GPU core speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 Texture Address Units, and 40 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 130		75 Watts
GeForce GTX 570		219 Watts
	Difference: 144 Watts (192%)

Memory Bandwidth

In theory, the GeForce GTX 570 should perform a lot faster than the GeForce GT 130 overall. (explain)

GeForce GTX 570		152000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 140000 (1167%)

Texel Rate

The GeForce GTX 570 should be quite a bit (more or less 266%) more effective at 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

The GeForce GTX 570 should be much (approximately 266%) more effective at AA than the GeForce GT 130, and will be able to handle higher resolutions better. (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 largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
