Compare any two graphics cards:
GeForce 8800 GT 512MB vs GeForce GTS 250 1GB
IntroThe GeForce 8800 GT 512MB has a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit memory bus, and makes use of a 65 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 ROPs.Compare all that to the GeForce GTS 250 1GB, which comes with GPU clock speed of 738 MHz, and 1024 MB of GDDR3 memory set to run at 1100 MHz through a 256-bit bus. It also features 128 SPUs, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 250 1GB should theoretically be much better than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce GTS 250 1GB will be quite a bit (more or less 41%) better at AF than the GeForce 8800 GT 512MB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTS 250 1GB is a better choice, 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 maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
