GeForce GT 130 vs Geforce GTX 670

Intro

Compare those specifications to the Geforce GTX 670, which features a clock speed of 915 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 256-bit bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 32 Raster Operation Units.

GeForce GT 130		75 Watts
Geforce GTX 670		170 Watts
	Difference: 95 Watts (127%)

Memory Bandwidth

The Geforce GTX 670, in theory, should perform a lot faster than the GeForce GT 130 overall. (explain)

Geforce GTX 670		192000 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 180000 (1500%)

Texel Rate

The Geforce GTX 670 is quite a bit (about 754%) more effective at AF than the GeForce GT 130. (explain)

Geforce GTX 670		102480 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 90480 (754%)

Pixel Rate

The Geforce GTX 670 is quite a bit (approximately 266%) better at full screen anti-aliasing than the GeForce GT 130, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Geforce GTX 670		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 maximum amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 most pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
