Compare any two graphics cards:
GeForce GTS 250 1GB vs GeForce GTX 480
IntroThe GeForce GTS 250 1GB uses a 65/55 nm design. nVidia has clocked the core frequency at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this particular card. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specs to the GeForce GTX 480, which comes with GPU clock speed of 700 MHz, and 1536 MB of GDDR5 RAM running at 924 MHz through a 384-bit bus. It also is comprised of 480 Stream Processors, 60 TAUs, and 48 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 480 is 152% faster than the GeForce GTS 250 1GB overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTS 250 1GB should be a small bit (about 12%) better at texture filtering than the GeForce GTX 480. (explain)
Pixel RateThe GeForce GTX 480 will be much (approximately 185%) faster with regards to AA than the GeForce GTS 250 1GB, and should be capable of handling higher screen resolutions more effectively. (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 (in units of megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
