GeForce GT 430 vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which has a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 256-bit bus, and makes use of a 40 nm design. It features 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce GT 430		60 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 110 Watts (183%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti should perform quite a bit faster than the GeForce GT 430 overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 99456 (345%)

Texel Rate

The GeForce GTX 560 Ti is a lot (more or less 370%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 41408 (370%)

Pixel Rate

The GeForce GTX 560 Ti is quite a bit (about 839%) faster with regards to full screen anti-aliasing than the GeForce GT 430, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 23504 (839%)

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 (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per 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 better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
