Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 980
IntroThe GeForce GTX 295 comes with a GPU core clock speed of 576 MHz, and the 896 MB of GDDR3 RAM is set to run at 999 MHz through a 448-bit bus. It also features 240 Stream Processors, 80 Texture Address Units, and 28 Raster Operation Units.Compare all of that to the GeForce GTX 980, which makes use of a 28 nm design. nVidia has set the core frequency at 1126 MHz. The GDDR5 RAM works at a speed of 1750 MHz on this particular card. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 980 should be 0% quicker than the GeForce GTX 295 in general, due to its higher bandwidth. (explain)
Texel RateThe GeForce GTX 980 should be much (more or less 56%) more effective at anisotropic filtering than the GeForce GTX 295. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 980 is a better choice, by a large margin. (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 maximum amount of data (in units of MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
