GeForce GT 430 (OEM) vs GeForce GTX 480

Intro

Compare those specs to the GeForce GTX 480, which makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR5 memory is set to run at a frequency of 924 MHz on this specific card. It features 480 SPUs as well as 60 Texture Address Units and 48 ROPs.

GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 148608 (516%)

Texel Rate

The GeForce GTX 480 is quite a bit (approximately 275%) more effective at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 30800 (275%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 480 is the winner, by a large margin. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 30800 (1100%)

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 data (counted in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
