Compare any two graphics cards:
GeForce GT 430 (OEM) vs GeForce GTX 275
IntroThe GeForce GT 430 (OEM) comes with a clock frequency of 700 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.Compare those specs to the GeForce GTX 275, which features a core clock frequency of 633 MHz and a GDDR3 memory frequency of 1134 MHz. It also uses a 448-bit bus, and makes use of a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 275 should theoretically be a lot faster than the GeForce GT 430 (OEM) overall. (explain)
Texel RateThe GeForce GTX 275 should be much (about 352%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 275 is a better choice, by a large margin. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 reach the maximum fill rate.
