GeForce GT 430 (OEM) vs GeForce GTX 275

Intro

Compare all of that to the GeForce GTX 275, which has GPU clock speed of 633 MHz, and 896 MB of GDDR3 memory set to run at 1134 MHz through a 448-bit bus. It also is comprised of 240 SPUs, 80 TAUs, and 28 ROPs.

Texel Rate

The GeForce GTX 275 should be a lot (approximately 352%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 39440 (352%)

Pixel Rate

The GeForce GTX 275 will be much (approximately 533%) more effective at AA than the GeForce GT 430 (OEM), and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 14924 (533%)

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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
