Compare any two graphics cards:
GeForce 9800 GT 512MB vs GeForce GTS 250 512MB
IntroThe GeForce 9800 GT 512MB uses a 65/55 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory runs at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 Texture Address Units and 16 Rasterization Operator Units.Compare that to the GeForce GTS 250 512MB, which uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this specific card. It features 128 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 512MB, in theory, should perform a lot faster than the GeForce 9800 GT 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB will be quite a bit (about 41%) better at texture filtering than the GeForce 9800 GT 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 250 512MB is the winner, 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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill 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 reach the maximum fill rate.
