Compare any two graphics cards:
GeForce GTS 250 512MB vs GeForce GTX 480
IntroThe GeForce GTS 250 512MB comes with a GPU core clock speed of 738 MHz, and the 512 MB of GDDR3 memory is set to run at 1100 MHz through a 256-bit bus. It also is comprised of 128 Stream Processors, 64 Texture Address Units, and 16 Raster Operation Units.Compare those specs to the GeForce GTX 480, which has GPU clock speed of 700 MHz, and 1536 MB of GDDR5 RAM set to run at 924 MHz through a 384-bit bus. It also is comprised of 480 SPUs, 60 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 480 should theoretically be much superior to the GeForce GTS 250 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB should be a bit (about 12%) more effective at texture filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 will be much (approximately 185%) faster with regards to full screen anti-aliasing than the GeForce GTS 250 512MB, and should be capable of handling higher resolutions without slowing down too much. (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 (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better 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 number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock speed of the card. 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
