Compare any two graphics cards:
GeForce GTS 250 512MB vs GeForce GTX 260
IntroThe GeForce GTS 250 512MB makes use of a 65/55 nm design. nVidia has set the core frequency at 738 MHz. The GDDR3 memory runs at a frequency of 1100 MHz on this model. It features 128 SPUs as well as 64 Texture Address Units and 16 Rasterization Operator Units.Compare those specifications to the GeForce GTX 260, which makes use of a 65 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM runs at a speed of 999 MHz on this card. It features 192 SPUs along with 64 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 260 should in theory be much better than the GeForce GTS 250 512MB in general. (explain)
Texel RateThe GeForce GTS 250 512MB will be much (approximately 28%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 260 is superior to the GeForce GTS 250 512MB, and very much so. (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 max amount of data (counted in MB per second) that can be transferred across 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 type 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 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the 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 the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
