GeForce GT 430 (OEM) vs GeForce GTS 450

Intro

Compare all that to the GeForce GTS 450, which features a GPU core clock speed of 783 MHz, and 512 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also is made up of 192 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 28928 (100%)

Texel Rate

The GeForce GTS 450 will be quite a bit (about 124%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTS 450		25056 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 13856 (124%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTS 450 is the winner, and very much so. (explain)

GeForce GTS 450		12528 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 9728 (347%)

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 largest amount of information (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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