GeForce GT 430 vs GeForce GTX 480

Intro

Compare those specifications to the GeForce GTX 480, which has core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce GTX 480		250 Watts
	Difference: 190 Watts (317%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 480 should in theory be quite a bit superior to the GeForce GT 430 overall. (explain)

GeForce GTX 480		177408 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 148608 (516%)

Texel Rate

The GeForce GTX 480 should be a lot (more or less 275%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

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

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is the winner, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce GT 430		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 largest amount of data (counted in megabytes per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, 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 processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

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