GeForce GT 130 vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which makes use of a 28 nm design. nVidia has set the core frequency at 980 MHz. The GDDR5 memory works at a speed of 1502 MHz on this specific model. It features 1152 SPUs as well as 96 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 130		75 Watts
Geforce GTX 760		170 Watts
	Difference: 95 Watts (127%)

Memory Bandwidth

In theory, the Geforce GTX 760 is 1502% faster than the GeForce GT 130 overall, due to its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 180256 (1502%)

Texel Rate

The Geforce GTX 760 should be quite a bit (more or less 684%) faster with regards to AF 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 quite a bit (about 292%) better at full screen anti-aliasing than the GeForce GT 130, and also 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 data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of 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.
