GeForce GT 130 vs GeForce GT 440 3GB

Intro

Compare all that to the GeForce GT 440 3GB, which comes with GPU clock speed of 594 MHz, and 3072 MB of GDDR3 RAM set to run at 900 MHz through a 192-bit bus. It also is made up of 144 SPUs, 24 TAUs, and 24 ROPs.

GeForce GT 440 3GB		56 Watts
GeForce GT 130		75 Watts
	Difference: 19 Watts (34%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 440 3GB should be 260% faster than the GeForce GT 130 in general, because of its higher data rate. (explain)

GeForce GT 440 3GB		43200 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 31200 (260%)

Texel Rate

The GeForce GT 440 3GB should be a bit (approximately 19%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)

GeForce GT 440 3GB		14256 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 2256 (19%)

Pixel Rate

The GeForce GT 440 3GB will be much (approximately 78%) better at full screen anti-aliasing than the GeForce GT 130, and will be capable of handling higher resolutions more effectively. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 6256 (78%)

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 megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 maximum fill rate.
