GeForce GT 430 (OEM) vs GeForce GTX 280

Intro

Compare those specs to the GeForce GTX 280, which has GPU clock speed of 602 MHz, and 1024 MB of GDDR3 RAM set to run at 1107 MHz through a 512-bit bus. It also is made up of 240 Stream Processors, 80 TAUs, and 32 ROPs.

GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 36960 (330%)

Pixel Rate

The GeForce GTX 280 should be quite a bit (approximately 588%) more effective at AA than the GeForce GT 430 (OEM), and capable of handling higher resolutions better. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 16464 (588%)

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 (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This is calculated by multiplying the total amount of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
