Compare any two graphics cards:
GeForce 920M vs Radeon HD 5750 512MB
IntroThe GeForce 920M features a GPU core speed of 954 MHz, and the 2048 MB of DDR3 RAM is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare that to the Radeon HD 5750 512MB, which makes use of a 40 nm design. AMD has clocked the core speed at 700 MHz. The GDDR5 memory is set to run at a speed of 1150 MHz on this specific model. It features 720(144x5) SPUs along with 36 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the Radeon HD 5750 512MB should in theory be much superior to the GeForce 920M overall. (explain)
Texel RateThe GeForce 920M will be quite a bit (more or less 21%) better at texture filtering than the Radeon HD 5750 512MB. (explain)
Pixel RateThe Radeon HD 5750 512MB will be much (more or less 47%) faster with regards to FSAA than the GeForce 920M, and able to handle higher resolutions without slowing down too much. (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 (counted in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount 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 calculated by multiplying the number of ROPs by the the card's 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 is also dependant on many 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.
