GeForce GT 430 vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which makes use of a 40 nm design. nVidia has set the core frequency at 732 MHz. The GDDR5 RAM works at a frequency of 950 MHz on this specific card. It features 480 SPUs as well as 60 TAUs and 40 Rasterization Operator Units.

Texel Rate

The GeForce GTX 570 will be much (more or less 292%) more effective at texture filtering than the GeForce GT 430. (explain)

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

Pixel Rate

The GeForce GTX 570 is a lot (more or less 946%) better at full screen anti-aliasing than the GeForce GT 430, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce GT 430		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 max amount of data (in units of MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines 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 rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
