Compare any two graphics cards:
GeForce 930M vs Radeon HD 3850 512MB
IntroThe GeForce 930M uses a 28 nm design. nVidia has clocked the core speed at 928 MHz. The DDR3 RAM works at a frequency of 900 MHz on this specific model. It features 384 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 3850 512MB, which uses a 55 nm design. AMD has clocked the core speed at 668 MHz. The GDDR3 RAM runs at a frequency of 828 MHz on this card. It features 320(64x5) SPUs as well as 16 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the Radeon HD 3850 512MB is 268% quicker than the GeForce 930M in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce 930M is much (about 108%) more effective at anisotropic filtering than the Radeon HD 3850 512MB. (explain)
Pixel RateThe Radeon HD 3850 512MB will be a lot (approximately 44%) faster with regards to FSAA than the GeForce 930M, and also able to handle higher screen resolutions more effectively. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip 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 number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
