Compare any two graphics cards:
GeForce 920M vs Radeon HD 5550
IntroThe GeForce 920M comes with 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 comprised of 384 Stream Processors, 32 Texture Address Units, and 8 ROPs.Compare that to the Radeon HD 5550, which has a GPU core clock speed of 550 MHz, and 512 MB of DDR2 memory set to run at 400 MHz through a 128-bit bus. It also features 320(64x5) Stream Processors, 16 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthAs far as performance goes, the GeForce 920M should theoretically be a little bit better than the Radeon HD 5550 overall. (explain)
Texel RateThe GeForce 920M will be a lot (approximately 247%) better at anisotropic filtering than the Radeon HD 5550. (explain)
Pixel RateThe GeForce 920M will be a lot (approximately 73%) faster with regards to AA than the Radeon HD 5550, and will be capable of handling higher resolutions without losing too much performance. (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 data (in units of megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory 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 anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
