Compare any two graphics cards:
GeForce GT 320 vs GeForce GT 430
IntroThe GeForce GT 320 features core speeds of 540 MHz on the GPU, and 790 MHz on the 1024 MB of GDDR3 RAM. It features 72 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the GeForce GT 430, which features core speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs along with 16 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 430, in theory, should perform a bit faster than the GeForce GT 320 overall. (explain)
Texel RateThe GeForce GT 320 should be a bit (approximately 16%) better at texture filtering than the GeForce GT 430. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GT 320 is superior to the GeForce GT 430, and very much so. (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 largest amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
