GeForce GT 430 1GB vs GeForce GTX 470

Intro

Compare that to the GeForce GTX 470, which comes with a core clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit memory bus, and makes use of a 40 nm design. It features 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 105120 (365%)

Texel Rate

The GeForce GTX 470 is a lot (about 204%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 470		33992 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 22792 (204%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 470 is the winner, and very much so. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 21480 (767%)

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 (measured in MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
