Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce GTS 250 1GB
IntroThe GeForce 8800 GT 512MB makes use of a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 112 SPUs along with 56 TAUs and 16 Rasterization Operator Units.Compare all that to the GeForce GTS 250 1GB, which has a core clock speed of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTS 250 1GB should in theory perform quite a bit faster than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce GTS 250 1GB is a lot (about 41%) more effective at AF than the GeForce 8800 GT 512MB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTS 250 1GB is superior to the GeForce 8800 GT 512MB, 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 max amount of information (counted in MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
