Compare any two graphics cards:
GeForce GTS 250 1GB vs GeForce GTS 450 1GB
IntroThe GeForce GTS 250 1GB has core speeds of 738 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR3 memory. It features 128 SPUs along with 64 Texture Address Units and 16 ROPs.Compare those specs to the GeForce GTS 450 1GB, which has GPU clock speed of 783 MHz, and 1024 MB of GDDR5 memory running at 902 MHz through a 128-bit bus. It also is comprised of 192 Stream Processors, 32 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTS 250 1GB should be 22% faster than the GeForce GTS 450 1GB in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTS 250 1GB is much (about 89%) faster with regards to texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTS 450 1GB is the winner, but it probably won't make a huge difference. (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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write 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 outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
