Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce 9800 GTX
IntroThe GeForce 8800 GT 1GB has clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the GeForce 9800 GTX, which has a core clock frequency of 675 MHz and a GDDR3 memory frequency of 1100 MHz. It also makes use of a 256-bit memory bus, and makes use of a 65 nm design. It features 128 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce 9800 GTX should perform a lot faster than the GeForce 8800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GTX is a lot (more or less 29%) better at AF than the GeForce 8800 GT 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX is superior to the GeForce 8800 GT 1GB, though only just barely. (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 maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster 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 amount of texture map elements (texels) that are applied 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 better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
