GeForce GT 130 vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which features GPU core speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also is made up of 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 130		12000 MB/sec
	Difference: 180256 (1502%)

Texel Rate

The Geforce GTX 760 is a lot (more or less 684%) more effective at texture filtering than the GeForce GT 130. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 82080 (684%)

Pixel Rate

The Geforce GTX 760 is a lot (approximately 292%) better at anti-aliasing than the GeForce GT 130, and should be able to handle higher resolutions without losing too much performance. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 23360 (292%)

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 information (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses 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, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
