Compare any two graphics cards:
GeForce GTX 260 vs GeForce GTX 275
IntroThe GeForce GTX 260 has core clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 memory. It features 192 SPUs as well as 64 Texture Address Units and 28 Rasterization Operator Units.Compare that to the GeForce GTX 275, which makes use of a 55 nm design. nVidia has set the core speed at 633 MHz. The GDDR3 RAM works at a speed of 1134 MHz on this specific model. It features 240 SPUs along with 80 TAUs and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 275 should theoretically be a bit superior to the GeForce GTX 260 in general. (explain)
Texel RateThe GeForce GTX 275 should be quite a bit (approximately 37%) more effective at anisotropic filtering than the GeForce GTX 260. (explain)
Pixel RateThe GeForce GTX 275 is a little bit (approximately 10%) faster with regards to FSAA than the GeForce GTX 260, and capable of handling higher screen resolutions without losing too much performance. (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 largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 can be applied in one second. This is worked out by multiplying the total amount of texture units of the card 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 applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
