Compare any two graphics cards:
GeForce 940M vs Radeon R9 M385X
IntroThe GeForce 940M comes with a GPU core speed of 1072 MHz, and the 2048 MB of DDR3 RAM runs at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 ROPs.Compare those specs to the Radeon R9 M385X, which features a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1500 MHz. It also makes use of a 128-bit bus, and uses a 28 nm design. It is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically speaking, the Radeon R9 M385X should be 500% faster than the GeForce 940M overall, because of its greater data rate. (explain)
Texel RateThe Radeon R9 M385X should be much (approximately 139%) more effective at anisotropic filtering than the GeForce 940M. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon R9 M385X is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
