Compare any two graphics cards:
GeForce GTX 980M vs Radeon HD 4550 512MB
IntroThe GeForce GTX 980M makes use of a 28 nm design. nVidia has clocked the core frequency at 1038 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this particular model. It features 1536 SPUs as well as 96 TAUs and 64 ROPs.Compare those specs to the Radeon HD 4550 512MB, which comes with a core clock speed of 600 MHz and a GDDR3 memory frequency of 800 MHz. It also uses a 64-bit memory bus, and makes use of a 55 nm design. It is made up of 80(16x5) SPUs, 8 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 980M should in theory be a lot faster than the Radeon HD 4550 512MB in general. (explain)
Texel RateThe GeForce GTX 980M is quite a bit (about 1976%) better at AF than the Radeon HD 4550 512MB. (explain)
Pixel RateThe GeForce GTX 980M should be much (approximately 2668%) better at anti-aliasing than the Radeon HD 4550 512MB, and also capable of handling higher resolutions more effectively. (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 data (counted in megabytes per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the card's bus 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 4 instead. The better the 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 can be processed per second. This is worked out by multiplying the total amount of texture units by the core 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 that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
