Compare any two graphics cards:
GeForce 9800 GT 1GB vs GeForce GTS 250 512MB
IntroThe GeForce 9800 GT 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 memory works at a speed of 900 MHz on this specific model. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GTS 250 512MB, which has GPU core speed of 738 MHz, and 512 MB of GDDR3 RAM set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTS 250 512MB should perform a lot faster than the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce GTS 250 512MB should be a lot (about 41%) faster with regards to AF than the GeForce 9800 GT 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 250 512MB is superior to the GeForce 9800 GT 1GB, 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: Bandwidth is the largest amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 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 texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record 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 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
