Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 870M
IntroThe GeForce GTX 295 comes with a clock speed of 576 MHz and a GDDR3 memory speed of 999 MHz. It also uses a 448-bit bus, and uses a 55 nm design. It features 240 SPUs, 80 Texture Address Units, and 28 Raster Operation Units.Compare all that to the GeForce GTX 870M, which features a core clock speed of 941 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 192-bit memory bus, and uses a 28 nm design. It is comprised of 1344 SPUs, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 295 should theoretically be a lot superior to the GeForce GTX 870M in general. (explain)
Texel RateThe GeForce GTX 870M should be a small bit (about 14%) faster with regards to AF than the GeForce GTX 295. (explain)
Pixel RateThe GeForce GTX 295 will be much (more or less 43%) better at anti-aliasing than the GeForce GTX 870M, and able to handle higher resolutions more effectively. (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: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the 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 amount of pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the card's clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
