Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GTX 580 3GB
IntroThe GeForce 9800 GT 1GB features a core clock speed of 600 MHz and a GDDR3 memory speed of 900 MHz. It also features a 256-bit bus, and uses a 65/55 nm design. It features 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 580 3GB, which comes with a clock frequency of 772 MHz and a GDDR5 memory frequency of 1002 MHz. It also features a 384-bit bus, and uses a 40 nm design. It features 512 SPUs, 64 Texture Address Units, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 580 3GB should theoretically perform quite a bit faster than the GeForce 9800 GT 1GB in general. (explain)
Texel RateThe GeForce GTX 580 3GB should be quite a bit (more or less 47%) faster with regards to texture filtering than the GeForce 9800 GT 1GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 3GB is superior to the GeForce 9800 GT 1GB, 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's 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 quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
