Compare any two graphics cards:
GeForce GTX 295 vs GeForce GTX 980M
IntroThe GeForce GTX 295 uses a 55 nm design. nVidia has clocked the core frequency at 576 MHz. The GDDR3 memory runs at a speed of 999 MHz on this specific model. It features 240 SPUs as well as 80 TAUs and 28 ROPs.Compare that to the GeForce GTX 980M, which comes with a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 295 should theoretically be a lot better than the GeForce GTX 980M overall. (explain)
Texel RateThe GeForce GTX 980M should be a little bit (approximately 8%) better at AF than the GeForce GTX 295. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 980M is the winner, 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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 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 this number, the better the 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 record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
