Compare any two graphics cards:
GeForce GTS 250 512MB vs GeForce GTX 465
IntroThe GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has set the core speed at 738 MHz. The GDDR3 memory works at a speed of 1100 MHz on this card. It features 128 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.Compare those specifications to the GeForce GTX 465, which has core clock speeds of 607 MHz on the GPU, and 802 MHz on the 1024 MB of GDDR5 RAM. It features 352 SPUs as well as 44 TAUs and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 465 should be much faster than the GeForce GTS 250 512MB overall. (explain)
Texel RateThe GeForce GTS 250 512MB will be a lot (approximately 77%) more effective at AF than the GeForce GTX 465. (explain)
Pixel RateThe GeForce GTX 465 is a lot (more or less 64%) better at AA than the GeForce GTS 250 512MB, and also will be able to handle higher resolutions better. (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 (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
