Compare any two graphics cards:
GeForce 920M vs GeForce GTX 295
IntroThe GeForce 920M features a core clock frequency of 954 MHz and a DDR3 memory speed of 900 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is comprised of 384 SPUs, 32 Texture Address Units, and 8 ROPs.Compare those specifications to the GeForce GTX 295, which uses a 55 nm design. nVidia has set the core frequency at 576 MHz. The GDDR3 RAM is set to run at a speed of 999 MHz on this model. It features 240 SPUs as well as 80 TAUs and 28 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce GTX 295 should theoretically perform quite a bit faster than the GeForce 920M overall. (explain)
Texel RateThe GeForce GTX 295 is much (more or less 202%) better at anisotropic filtering than the GeForce 920M. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 295 is a better choice, and very much so. (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 MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 maximum amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
