GeForce GT 430 (OEM) vs GeForce GTX 570

Intro

Compare all that to the GeForce GTX 570, which features a GPU core clock speed of 732 MHz, and 1280 MB of GDDR5 memory set to run at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 Texture Address Units, and 40 Raster Operation Units.

Texel Rate

The GeForce GTX 570 should be much (approximately 292%) more effective at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 32720 (292%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 26480 (946%)

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 maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 are applied in one second. This 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 rate also depends 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 max fill rate.
