GeForce GT 430 1GB vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which has a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM set to run at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 99328 (345%)

Texel Rate

The GeForce GTX 560 is a lot (more or less 305%) better at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 34160 (305%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is superior to the GeForce GT 430 1GB, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 23120 (826%)

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 data (in units of MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better 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 maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
