GeForce GT 130 vs GeForce GTX 480

Intro

Compare those specifications to the GeForce GTX 480, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 memory works at a speed of 924 MHz on this particular model. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

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

Pixel Rate

The GeForce GTX 480 should be a lot (about 320%) faster with regards to full screen anti-aliasing than the GeForce GT 130, and should be able to handle higher resolutions better. (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 information (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
