Compare any two graphics cards:
GeForce 920M vs GeForce GTX 460 1GB
IntroThe GeForce 920M features clock speeds of 954 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs along with 32 TAUs and 8 ROPs.Compare those specs to the GeForce GTX 460 1GB, which features clock speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 RAM. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce GTX 460 1GB should be quite a bit faster than the GeForce 920M in general. (explain)
Texel RateThe GeForce GTX 460 1GB is much (more or less 24%) more effective at texture filtering than the GeForce 920M. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 460 1GB 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card 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 processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
