Compare any two graphics cards:
GeForce GT 230 vs GeForce GT 430
IntroThe GeForce GT 230 features a GPU clock speed of 550 MHz, and the 1536 MB of DDR3 RAM runs at 800 MHz through a 192-bit bus. It also is made up of 32 SPUs, 16 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GT 430, which comes with GPU core speed of 700 MHz, and 512 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 230 should in theory be much better than the GeForce GT 430 in general. (explain)
Texel RateThe GeForce GT 430 will be much (approximately 27%) better at anisotropic filtering than the GeForce GT 230. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 230 is superior to the GeForce GT 430, by far. (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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
