Compare any two graphics cards:
GeForce GTX 260 Core 216 vs GeForce GTX 295
IntroThe GeForce GTX 260 Core 216 has a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 memory runs at 999 MHz through a 448-bit bus. It also features 216 Stream Processors, 72 Texture Address Units, and 28 Raster Operation Units.Compare all of that to the GeForce GTX 295, which makes use of a 55 nm design. nVidia has set the core speed at 576 MHz. The GDDR3 RAM runs at a speed of 999 MHz on this specific model. It features 240 SPUs as well as 80 TAUs and 28 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 295 should theoretically be a lot superior to the GeForce GTX 260 Core 216 in general. (explain)
Texel RateThe GeForce GTX 295 will be quite a bit (approximately 122%) more effective at texture filtering than the GeForce GTX 260 Core 216. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 295 is a better choice, by far. (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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out 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 applied per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
