Compare any two graphics cards:
GeForce GT 130 vs GeForce GTX 470
IntroThe GeForce GT 130 features core clock speeds of 500 MHz on the GPU, and 250 MHz on the 768 MB of DDR2 RAM. It features 48 SPUs as well as 24 TAUs and 16 Rasterization Operator Units.Compare those specs to the GeForce GTX 470, which has a core clock frequency of 607 MHz and a GDDR5 memory frequency of 837 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is made up of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 470, in theory, should be a lot faster than the GeForce GT 130 overall. (explain)
Texel RateThe GeForce GTX 470 is quite a bit (about 183%) faster with regards to anisotropic filtering than the GeForce GT 130. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GT 130, 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 maximum amount of information (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher 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 video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
