GeForce GT 130 vs GeForce GTX 480

Intro

Compare all that to the GeForce GTX 480, which comes with core clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 RAM. It features 480 SPUs along with 60 TAUs and 48 ROPs.

GeForce GT 130		75 Watts
GeForce GTX 480		250 Watts
	Difference: 175 Watts (233%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 should perform a lot faster than the GeForce GT 130 in general. (explain)

GeForce GTX 480		177408 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 165408 (1378%)

Texel Rate

The GeForce GTX 480 should be much (approximately 250%) better at AF than the GeForce GT 130. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce GT 130		12000 Mtexels/sec
	Difference: 30000 (250%)

Pixel Rate

The GeForce GTX 480 will be quite a bit (about 320%) more effective at anti-aliasing than the GeForce GT 130, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GT 130		8000 Mpixels/sec
	Difference: 25600 (320%)

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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 are applied in one second. This figure is worked out by multiplying the total texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
