Compare any two graphics cards:
GeForce 920M vs Radeon HD 4550 512MB
IntroThe GeForce 920M makes use of a 28 nm design. nVidia has set the core frequency at 954 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this particular model. It features 384 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.Compare those specs to the Radeon HD 4550 512MB, which has GPU clock speed of 600 MHz, and 512 MB of GDDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthTheoretically, the GeForce 920M should be just a bit faster than the Radeon HD 4550 512MB overall. (explain)
Texel RateThe GeForce 920M will be much (about 536%) faster with regards to anisotropic filtering than the Radeon HD 4550 512MB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce 920M is superior to the Radeon HD 4550 512MB, by far. (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 max amount of information (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the 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 maximum amount of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
