Compare any two graphics cards:
GeForce 830M vs Radeon HD 4550 256MB
IntroThe GeForce 830M has core speeds of 1029 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 256 SPUs as well as 16 TAUs and 8 ROPs.Compare all that to the Radeon HD 4550 256MB, which features GPU core speed of 600 MHz, and 256 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is made up of 80(16x5) SPUs, 8 TAUs, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the GeForce 830M should theoretically be a small bit superior to the Radeon HD 4550 256MB in general. (explain)
Texel RateThe GeForce 830M will be quite a bit (more or less 243%) more effective at anisotropic filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce 830M is superior to the Radeon HD 4550 256MB, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 applied per second. This 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
