Compare any two graphics cards:
GeForce 920M vs Radeon HD 5450
IntroThe GeForce 920M features a GPU core clock speed of 954 MHz, and the 2048 MB of DDR3 memory is set to run at 900 MHz through a 64-bit bus. It also is made up of 384 Stream Processors, 32 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 5450, which comes with GPU core speed of 650 MHz, and 512 MB of DDR3 memory set to run at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) Stream Processors, 8 TAUs, and 4 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthIn theory, the GeForce 920M should perform a bit faster than the Radeon HD 5450 overall. (explain)
Texel RateThe GeForce 920M is much (about 487%) faster with regards to AF than the Radeon HD 5450. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 920M 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
