GeForce GT 430 (OEM) vs GeForce GTX 470

Intro

Compare that to the GeForce GTX 470, which features a clock speed of 607 MHz and a GDDR5 memory speed of 837 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 TAUs, and 40 ROPs.

GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 22792 (204%)

Pixel Rate

The GeForce GTX 470 will be quite a bit (more or less 767%) more effective at AA than the GeForce GT 430 (OEM), and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GT 430 (OEM)		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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
