GeForce GT 430 (OEM) vs GeForce GTX 275

Intro

Compare all that to the GeForce GTX 275, which comes with a clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also uses a 448-bit memory bus, and makes use of a 55 nm design. It is made up of 240 SPUs, 80 TAUs, and 28 ROPs.

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

Pixel Rate

The GeForce GTX 275 will be quite a bit (approximately 533%) more effective at FSAA than the GeForce GT 430 (OEM), and will be able to handle higher screen resolutions better. (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: Bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
