Compare any two graphics cards:
GeForce GT 230 vs GeForce GTX 480
IntroThe GeForce GT 230 comes with core clock speeds of 550 MHz on the GPU, and 800 MHz on the 1536 MB of DDR3 RAM. It features 32 SPUs along with 16 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the GeForce GTX 480, which comes with a clock speed of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also makes use of a 384-bit memory bus, and makes use of a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 480 should theoretically be a lot superior to the GeForce GT 230 overall. (explain)
Texel RateThe GeForce GTX 480 is a lot (more or less 377%) better at texture filtering than the GeForce GT 230. (explain)
Pixel RateThe GeForce GTX 480 should be much (more or less 664%) better at anti-aliasing than the GeForce GT 230, and also should be able to handle higher screen resolutions more effectively. (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 data (in units of MB per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
