Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 275
IntroThe GeForce GTX 260 Core 216 comes with clock speeds of 576 MHz on the GPU, and 999 MHz on the 896 MB of GDDR3 RAM. It features 216 SPUs along with 72 Texture Address Units and 28 ROPs.Compare those specifications to the GeForce GTX 275, which comes with a core clock frequency of 633 MHz and a GDDR3 memory speed of 1134 MHz. It also features a 448-bit memory bus, and makes use of a 55 nm design. It features 240 SPUs, 80 TAUs, and 28 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 275 should in theory be a little bit faster than the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 275 will be much (about 22%) more effective at anisotropic filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateThe GeForce GTX 275 is a bit (more or less 10%) better at anti-aliasing than the GeForce GTX 260 Core 216, and also will be capable of handling higher screen 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: Bandwidth is the largest amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units 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 rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
