Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GT 430
IntroThe GeForce 9500 GT 512MB GDDR3 makes use of a 55 nm design. nVidia has set the core speed at 550 MHz. The GDDR3 RAM is set to run at a speed of 800 MHz on this card. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare that to the GeForce GT 430, which features clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GT 430 should in theory be a small bit superior to the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GT 430 is quite a bit (about 27%) more effective at anisotropic filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateThe GeForce 9500 GT 512MB GDDR3 is quite a bit (about 57%) faster with regards to FSAA than the GeForce GT 430, and also should be able to handle higher screen resolutions better. (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: Bandwidth is the max amount of information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
