GeForce GT 430 (OEM) vs GeForce GTX 280

Intro

Compare all that to the GeForce GTX 280, which features a core clock frequency of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also uses a 512-bit memory bus, and makes use of a 65 nm design. It is made up of 240 SPUs, 80 TAUs, and 32 ROPs.

GeForce GT 430 (OEM)		60 Watts
GeForce GTX 280		236 Watts
	Difference: 176 Watts (293%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 should be 392% faster than the GeForce GT 430 (OEM) overall, because of its higher bandwidth. (explain)

GeForce GTX 280		141696 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 112896 (392%)

Texel Rate

The GeForce GTX 280 will be much (more or less 330%) better at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 36960 (330%)

Pixel Rate

The GeForce GTX 280 is quite a bit (more or less 588%) better at FSAA than the GeForce GT 430 (OEM), and also able to handle higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 are applied in one second. This is worked out by multiplying the total number of texture units of the card by the core 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
