Compare any two graphics cards:
GeForce 930M vs Radeon HD 4550 256MB
IntroThe GeForce 930M makes use of a 28 nm design. nVidia has clocked the core speed at 928 MHz. The DDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 4550 256MB, which features a core clock speed of 600 MHz and a DDR3 memory speed of 800 MHz. It also features a 64-bit memory bus, and makes use of a 55 nm design. It features 80(16x5) SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical BenchmarksMemory BandwidthThe GeForce 930M should in theory perform a bit faster than the Radeon HD 4550 256MB in general. (explain)
Texel RateThe GeForce 930M is much (approximately 364%) better at anisotropic filtering than the Radeon HD 4550 256MB. (explain)
Pixel RateThe GeForce 930M will be a lot (more or less 209%) faster with regards to anti-aliasing than the Radeon HD 4550 256MB, and also should be able to handle higher screen resolutions better. (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 maximum amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
