Compare any two graphics cards:
GeForce 940M vs Radeon HD 5830
IntroThe GeForce 940M makes use of a 28 nm design. nVidia has clocked the core frequency at 1072 MHz. The DDR3 memory works at a frequency of 1000 MHz on this specific card. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.Compare those specifications to the Radeon HD 5830, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this card. It features 1120(224x5) SPUs as well as 56 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 5830 should be much faster than the GeForce 940M overall. (explain)
Texel RateThe Radeon HD 5830 is quite a bit (more or less 74%) more effective at anisotropic filtering than the GeForce 940M. (explain)
Pixel RateThe Radeon HD 5830 should be a lot (about 49%) better at FSAA than the GeForce 940M, and will be able to handle higher resolutions better. (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 largest amount of data (counted in megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
